1 Quick overview

For a quick tutorial see @{"Tutorial/Tutorial.readme" ALINK "Tutorial/Tutorial.readme/Main"}.

TSMorph is a set of morphing programs. It consists of two programs:

TSMorph         Edit the Morph parameters
TSMorph-render  Generate the morphed images

TSMorph is used to create a parameter file which is used by TSMorph-render to produce the morphed images. TSMorph-render works with 24 bit internally. Run times can be about 3 seconds per frame for a 150x150 image on a 28Mhz 68040 - See Benchmarks.

TSMorph-render can be used to morph one image to another in a set number of frames with a number of control points, just distort one image with control points. It can also be used to morph or warp a series of images (e.g. to morph between two animations). When TSMorph is run without parameters it will display an ASL file requester for a file created by TSMorph, it will then create the images, displaying a Progress Requester on the default (or named) public screen allowing the process to be interrupted and/or stopped.

ARexx scripts are run before and after each image is processed, and also before each image is loaded. These allow the changing of movement and colour to be controlled along with the ability to only generate some frames, and also pre and post image processing (e.g. to change to a non-24-bit format and build an animation).

TSMorph is used to generate the parameter file. When run it displays an Information Window on a public screen. This allows the input of the file names to morph between, the number of frames, the start frame, the output file names, and the type of morph (single or dual images) to be changed.

It also allows the editing of control points on the images. The images (most image formats can be loaded - See OPENMODE) are displayed on a public screen in resizeable, scrollable windows.

When the images are displayed control points can be edited in various modes. These modes allow the addition, deletion, linking and unlinking of the control points.

Context sensitive help is displayed using amigaguide (if available). The Help key can be pressed in the gadgets, over the gadgets, on menus or anytime a window is active.

2 Installation instructions

If you wish to use Installer then TSMorph can be installed using the supplied script. If not then the following is a description of what the script does.

• 1) Make a new drawer for the executables - default Work:TSMorph,
• 2) Copy TSMorph, TSMorph-render, TSMorph.doc, TSMorph.guide, TSMorph-prefs and the Rexx drawer and its contents and all their icons to the drawer created in 1) above (if you have a 68020/030 with 68881/2 then copy the FPU version TSMorph-render.881 and rename it as TSMorph-render instead of copying TSMorph-render, or if you have a 68040 then copy the 040 version TSMorph-render.040 and rename it as TSMorph-render instead of copying TSMorph-render)
• 3) If required copy the Brush and Cursor drawers and contents.
• 4) Make new drawers ENVARC:TSMorph and ENV:TSMorph,
• 5) Copy the default Icons to the directories created above.
• 6) Amend your s:user-startup to assign TSMorph: to the drawer created in step 1).
• 7) Manually perform the assign in step 6).
• 8) If you are running system version 3.0 (or greater) change the default tool for TSMorph.guide to MultiView.
• 9) If required copy the Tutorial directory to TSMorph:.
• 10) If required copy the HTML directory to TSMorph:, also copy the View_HTML icon and use an editor to make the file contain:

    CD HTML
    Path:Mosaic file://localhost/TSMorph:html/TSMorph.html

        Where Path:Mosaic is the location of your version of Mosaic.

3 Software and Hardware required

The following libraries (with minimum version) are required to run TSMorph:

intuition.library        37
iffparse.library         37
graphics.library         37
layers.library           37
gadtools.library         37
asl.library              37

diskfont.library         36
icon.library             37
rexxsyslib.library       0

The following will also be used if present:

amigaguide.library       34
dctv.library             3
opal.library             0  Note: OpalVision board is not required

TSMorph-render requires a large amount of chip memory (or opal.library). If you have 1Mb then 512x512 images can be morphed (though you may have to run workbench on a 2 colour 640x200 screen). 640x512 is probably impossible without 2Mb of chip memory.

The amount of chip memory required by TSMorph can be reduced to 1/5 by setting the ZOOM parameter to OFF.

4 Tool types and Shell parameters

Both TSMorph and TSMorph-render can be run from the Shell or the Workbench. Most parameters can be edited using the Settings menu.

Note: TSMorph and TSMorph-render both require a stack size of more than 4096. 8192 should be OK. If the stack is not set large enough then the programs will probably just crash.

Parameters can be supplied, normally either on the Shell command line, as Icon Tool Types on the Project, TSMorph or TSMorph-render Icon, or in a settings file.

The format of settings files is a text file with lines in the format:

Settingstype=settingsvalue

Blank lines or lines starting with a ; (semi-colon) are treated as comments. Any settings supplied on the Shell command line or as an Icon Tool Type override values specified in this file. Parameters on the Project Icon override parameters on the Tool Icon.

Note: All the Project Icon tool types are used if the project is run with a default tool or by double clicking a tool, some are not used if the project is selected using a file requester, if the Tool was run from the Shell then file requester selected project tool types are ignored. Also some settings can not be changed on open projects,

The Settings file name used is first file found from:

1) The name supplied in the SETTINGS= parameter on the project.
2) The name supplied in the SETTINGS= parameter on the tool.
3) TSMorph.prefs
   in the project directory for the workbench,
   the current directory from the Shell.
4) TSMorph.prefs
   in the directory TSMorph was loaded from.
5) ENV:TSMorph/TSMorph.prefs

Unless KEEPSETTINGS is set to NO current settings are saved in ENV:TSMorph/TSMorph.prefs when TSMorph is quit. Settings can be saved and loaded from the Settings menu.

Parameters to TSMorph

The following parameters can be supplied, normally either on the Shell command line, as Icon Tool Types on the Project or TSMorph Icon, or in a settings file:

CHANGEPALETTE=YES/NO/OFF

Sets the default value of the Change Palette? settings menu item - defaults to YES.

This item toggles if each images palette should be used to display the image when the window is active. Each image window can have its own palette. This option operates with the OPENMODE parameter.

Since the ability to change screens colour palettes is not supported by CBM this menu option can be disabled by setting this parameter to OFF.

CREATEICONS=YES/NO

Sets the default value of the Create Icons? settings menu item - defaults to YES.

This item toggles if Icons are to be saved with parameter files. If it is selected then an Icon will be saved. The icon will come from ENV:TSMorph/def_points if this exists, secondly from ENV:SYS/def_points, otherwise the default project Icon is used.

This parameter is not changed by Requester loaded projects.

CREATEICONSP=YES/NO

Sets the default value of the Create Prefs Icons? settings menu item - defaults to YES.

This item toggles if Icons are to be saved with Settings files. If it is selected then an Icon will be saved. The icon will come from ENV:TSMorph/def_prefs if this exists, secondly from ENV:SYS/def_prefs, otherwise the default project Icon is used.

CUSTOMDEPTH=4

This gives the depth of the custom screen to open if CUSTOMMODE is specified.

It can be changed using the menu item (if reqtools.library is available), a requester is displayed allowing the input of the screen mode, but any change is ignored until TSMorph is reloaded.

The default value is 4.

CUSTOMMODE=screen_mode

This gives the mode of the custom screen to open.

The mode is as show in the Screen Mode requester - case is ignored (e.g. "PAL:Low Res"). This parameter is not changed by Requester loaded projects.

The name of the screen must be given by the PUBSCREEN parameter. The depth is given by the CUSTOMDEPTH parameter. The screen will mostly clone the Workbench, but other colours will be set up as a grey scale.

It can be changed using the menu item (if reqtools.library is available), a requester is displayed allowing the input of the screen mode, but any change is ignored until TSMorph is reloaded.

The default value is nothing which means do not open a custom screen.

EGS=YES/NO

This controls the use of EGS when displaying the edit windows. See requirements for library requirements. If set to yes then the edit windows and relevent error requesters are displayed on the default EGS screen.

ZOOM is always set to OFF when using EGS. OPENMODE may also be ignored in some circumstances.

This parameter is not available as a menu option, is not saved in settings files and can not be specified on a project Icon.

Default values is NO.

FILES=filename

This is only relevant to the Shell, only one name can be supplied - default is to open a new unnamed project.

HELP=YES/NO

Sets the default value of the Continuous Help? settings menu item - defaults to NO.

This option has more effect when running release 3.0 or later. When set to YES help is continuously displayed using amigaguide (if available).

KEEPSETTINGS=YES/NO

Sets the default value of the Keep Settings? settings menu item - defaults to YES.

By default current settings are saved in ENV:TSMorph/TSMorph.prefs when TSMorph is quit. This parameter and menu item enable this behaviour to be turned off.

OPENMODE=ALWAYS/IFILBM/IFCOLOURS/REMAP/OPAL

This parameter and menu item specify how images should be loaded for displaying by TSMorph.

• ALWAYS - Only try and load normal ILBM images. Fail if not. The CHANGEPALETTE parameter has an affect on the image display.
• IFILBM - First try to load as an ILBM image, load and remap the image if the image is not an ILBM or has 24 planes.
• IFCOLOURS - As IFILBM but remap if the number of planes in the image exceed the number of the screen.
• REMAP - Loads most ILBM (including 24 bit, EHB, HAM6, HAM8 and DCTV (with dctv.library [REMAP needs to be specified to correctly display DCTV images]), JPEG, TARGA, PPM and GIF. For JPEG if CHANGEPALETTE=YES or NO and the screen (see PUBSCREEN) has more than 2 bit planes then the image is remapped to a dynamic type palette. Otherwise the image is remapped to the screen palette. If this fails then opal.library will be used (if present). This may be required for some JPEGs.
• OPAL - Always use opal.library to load the image. This is probably only useful to load images in Opal FAST IFF format. The images are remapped to the current palette.

When loading and remapping complex images a requester is displayed with a title of Loading Image, a text gadget giving progress messages, a Pass gadget, and a third progress gadget. There is no way of interrupting the load process.

For slow machines it is suggested that you convert the images to ILBMs and specify ALWAYS.

PREVIEW=scriptname

This specifies the name of an ARexx script to run to preview the rendered image.

The default script is @{"Rexx/Preview" ALINK "Rexx/Preview.TSM/Main"}.

The version supplied renders the image as a 16 colour grey scale with a resolution of about 128/64 and displays it.

It can be changed using the menu item (if reqtools.library is available), a requester is displayed allowing the input of the value.

PUBSCREEN=pubscreenname

This gives the name of the Public Screen on which to open all TSMorph windows - default is the default public screen.

This parameter is not changed by Requester loaded projects.

It can be changed using the menu item (if reqtools.library is available), a requester is displayed allowing the input of the screen name, but any change is ignored until TSMorph is reloaded.

If CUSTOMMODE is supplied as well then a public screen of this name is opened.

REQTOOLS=YES/NO/ALL

This controls the use of reqtools.library. If set to NO then reqtools will not be used (except in very unusual circumstances). It will still however be opened and closed. If set to YES then reqtools will be used for various requesters. If set to ALL then it will be used for the File Requesters as well.

This parameter is not available as a menu option, is not saved in settings files and can not be specified on a project Icon.

Default values is YES.

SETTINGS=filename

This can only be supplied on the Shell command line, or an Icon Tool Type. It specifies the name of a file for more parameters. See section parameters.

This parameter is not changed by Requester loaded projects.

ZOOM=YES/NO/OFF

Sets the default value of the Zoom? settings menu item. If set to YES then images will be initially displayed 2x normal size, if set to NO then images will be initially displayed normal size, setting to OFF disables the Zoom? option, this reduces chip memory usage to 1/5 - defaults to NO.

Parameters to TSMorph-render

The following parameters can be supplied, normally either on the Shell command line, as Icon Tool Types on the Project or TSMorph-render Icon, or in a settings file:

ANTIALIAS=NO/YES

This parameter and menu item select if the output files should be Anti-Aliased. Setting to YES can improve the quality of the images but will slow down the rendering process.

This parameter is ignored if INTEGER is set to YES.

Default value is NO.

CREATEICONSR=NO/YES

This parameter and menu item selects if Icons are to be saved with image files. If it is YES then an Icon will be saved. The icon depends on the save format.

ENV:TSMorph/def_bw16  - 16 colour grey scale images
ENV:TSMorph/def_bw256 - 256 colour grey scale images
ENV:TSMorph/def_ham6  - HAM 6 images
ENV:TSMorph/def_ham8  - HAM 8 images
ENV:TSMorph/def_dctv3 - DCTV 3 plane images using dctv.library
ENV:TSMorph/def_dctv4 - DCTV 4 plane images using dctv.library
ENV:TSMorph/def_iff   - 24 bit ILBM saved using opal.library
ENV:TSMorph/def_ilbm  - 24 bit ILBM saved without opal.library
ENV:TSMorph/def_jpg   - JPEG files saved using opal.library
ENV:TSMorph/def_ppm   - PPM files

If the file does not exist then ENV:SYS/def_ilbm (etc.) is tried, if this does not exist then the default project Icon is used.

Default value is NO.

DEPTH=number

This parameter indicates how deep the Morphing algorithm should search to find the points to use for morphing. The maximum value is 20 (higher values are accepted but will be taken as 20).

Default value is 2.

It can be changed using the menu item (if reqtools.library is available), a requester is displayed allowing the input of the value.

DX=number

This parameter can be used to speed up the rendering process. The default value is 0.

If set to a number then only some Horizontal pixels will be generated. e.g. if set to 3 then only every 4th pixel will be generated. The others will be copied from the previous pixel. This can be overridden by using ARexx. Also see DY.

It can be changed using the menu item (if reqtools.library is available), a requester is displayed allowing the input of the value.

DY=number

This parameter can be used to speed up the rendering process. The default value is 0.

If set to a number then only some Vertical pixels will be generated. e.g. if set to 1 then only every other line will be generated. The others will be copied from the previous line. This can be overridden by using ARexx. Also see DX.

It can be changed using the menu item (if reqtools.library is available), a requester is displayed allowing the input of the value.

EGS=YES/NO

By default TSMorph-render does not show its output when rendering. If this parameter is set to YES then output will be displayed in an EGS window on the default EGS screen a line at a time. See requirements for library requirements.

This parameter is not available as a menu option, is not saved in settings files and can not be specified on a project Icon.

Default values is NO.

FILES=filename

This is only relevant to the Shell, only one name can be supplied - default is to show an ASL file requester for the file to run.

INTEGER=NO/YES

This parameter and menu item select if the render process should use integer or floating point arithmetic. The process will be faster if integer arithmetic is used (especially on machines without an FPU). However the output quality will not be so good.

If this parameter is set to YES then the ANTIALIAS parameter is ignored.

Default value is NO.

LOADSCRIPT=Scriptname/OFF

This specifies the name of an ARexx script to run before each image 24 bit image is loaded. This can be used to e.g. hold the images on disc in JPEG format to save space and convert each image back to 24 bit ILBM when required. Note however that TSMorph-render now has the ability to load a large variety of image formats (All ILBM including HAM6, HAM8, EHB, and DCTV with dctv.library, JPEG, TARGA, PPM, and GIF).

The default script is @{"Rexx/Loadscript" ALINK "Rexx/Loadscript.TSM/Main"}.

The version supplied does nothing.

Set to OFF to run no script.

It can be changed using the menu item (if reqtools.library is available), a requester is displayed allowing the input of the value.

MODE=0-31

This parameter and menu item indicate how the Morphing algorithm should search to find the points to use for morphing.

The values are additive:

   1 : Leaves un-triangled point stationary
   2 : Searches all the closest points
   4 : Uses a squaring algorithm to find close points
   8 : Uses a Delaunay algorithm to find triangles
   16: Precalculate close points

Default value is 0.

POSTSCRIPT=Scriptname/OFF

This specifies the name of an ARexx script to run after each image is rendered. This can be used to build an animation or change the image format from 24 bit.

The default script is @{"Rexx/Postscript" ALINK "Rexx/Postscript.TSM/Main"}.

The version supplied does nothing.

Set to OFF to run no script.

It can be changed using the menu item (if reqtools.library is available), a requester is displayed allowing the input of the value.

PRESCRIPT=Scriptname/OFF

This specifies the name of an ARexx script to run before each image is rendered. This can be used to produce only some of the frames and control the movement and colour of the images.

The default script is @{"Rexx/Prescript" ALINK "Rexx/Prescript.TSM/Main"}.

The version supplied does nothing.

Set to OFF to run no script.

It can be changed using the menu item (if reqtools.library is available), a requester is displayed allowing the input of the value.

PUBSCREENR=pubscreenname

This gives the name of the Public Screen on which to open TSMorph-render windows - default is the default public screen.

It can be changed using the menu item (if reqtools.library is available), a requester is displayed allowing the input of the screen name.

QUALITY=number

This specifies the quality of output files. This option only applies if opal.library is available and SAVEFORMAT is JPEG or JPEGT. Possible values are 0 to 100.

Default value is 75.

It can be changed using the menu item (if reqtools.library is available), a requester is displayed allowing the input of the value.

REQTOOLS=YES/NO/ALL

This controls the use of reqtools.library. If set to NO then reqtools will not be used (except in very unusual circumstances). It will still however be opened and closed. If set to YES then reqtools will be used for various requesters. If set to ALL then it will be used for the File Requesters as well.

This parameter is not available as a menu option, is not saved in settings files and can not be specified on a project Icon.

Default values is YES.

SAVEFORMAT=ILBM24/OPAL24/OPAL24T/OPAL24F/OPAL24FT/JPEG/JPEGT/PPM/BW16/BW256/HAM6/HAM8/DCTV3/DCTV4

This parameter and menu item specify the format TSMorph-render should use to save the output images. OPAL and JPEG formats are only available if opal.library is available. DCTV3 and DCTV4 formats are only available if dctv.library is available.

ILBM24   - IFF 24 bit ILBM with no CAMG chunk
OPAL24   - IFF 24 bit ILBM saved using opal.library
OPAL24T  - as OPAL24 with a Thumbnail
OPAL24F  - as OPAL24 in Fast Format
OPAL24TF - as OPAL24F with a Thumbnail
JPEG     - JPEG format using opal.library
JPEGT    - as JPEG with a Thumbnail
PPM      - PPM format
BW16     - ILBM 16 colour grey scale
BW256    - ILBM 256 colour grey scale
HAM6     - ILBM 6 plane HAM
HAM8     - ILBM 8 plane HAM
DCTV3    - ILBM 3 plane DCTV using dctv.library
DCTV4    - ILBM 4 plane DCTV using dctv.library

The quality of JPEG images can be set using the QUALITY parameter.

PPM format is basically uncompressed 24 bit. The files are therefore very large and it is suggested that a compressing file handler (such as XFH or EPU) is used. This format is provided mainly to allow the easy production of MPEG movies.

The save format also controls which Icon is saved with the image.

SETTINGS=filename

This can only be supplied on the Shell command line, or an Icon Tool Type.

This specifies the name of a file to contain settings. See section parameters.

TOOLPRI=number

This can only be supplied as a Tool Icon tool type. It sets the priority of the rendering process.

Setting to -1 is a good idea if you wish to run the program in the background. The default value is 0. Setting to positive values is generally not a good idea.

5 The Information Window

This window is always displayed when TSMorph is running. It displays information about the current project. The window title is TSMorph, the screen title will be displayed as the project name if the project has a name. It is used to set up all the information required by TSMorph-render.

ARexx scripts are run before and after each image is rendered, and before each 24 bit image is loaded. The script names can be supplied as parameters (LOADSCRIPT, PRESCRIPT and POSTSCRIPT) to TSMorph-render.

An ARexx script can also be run by TSMorph to preview render an image. The script name is supplied in the PREVIEW parameter.

The suffix to each ARexx script should be .TSM.

ARexx script run before loading 24 bit image

This script is run before each 24 bit ILBM image is loaded.

It is passed the following parameters:

Frame       : The current frame number, starting at Start.
TotalFrames : The total number of frames being rendered.
Single      : Set to 1 if a Warp, 0 for a Morph, 2 for Anim Morph, 3 for Anim Warp.
Image       : Set to 0 for 1st image, 1 for second.
FileName    : Name of file just rendered.

This script can be used to change the format of the input file (by running it through a conversion program).

One example is included: @HTML <P> @HTMLOFF

ARexx script run before rendering

This script is run before each image is rendered.

It is also called for the first image (for warps and morphs) and for the last image (for morphs). By default the first and last frames are not rendered. Produce will need to be set to 1 to output these frames. This allows the first and last frames to be converted to the same format as the other output images.

It is passed one parameter - Base - the address of a structure which contains the following:

Frame       = 0  : The current frame number, starting at 1 (0 for 1st frame) - read only.
TotalFrames = 1  : The total number of frames being rendered - read only.
Single      = 2  : Set to 1 if a Warp, 0 = Morph, 2 = Anim Morph, 3 = Anim Warp - read only.
Movement    = 3  : 0 to 1024 - the proportion of movement from first to second image.
Red1        = 4  : 0 to 1024 - the proportion of Image 1 Red to use.
Green1      = 5  : As Red1 for Green.
Blue1       = 6  : As Red1 for Blue.
Red2        = 7  : 0 to 1024 - the proportion of Image 2 Red to use.
Green2      = 8  : As Red2 for Green.
Blue2       = 9  : As Red2 for Blue.
Produce     = 10 : Set to 0 to not render this frame, 1 otherwise.
RPlus       = 11 : 0 to 255 to add to Red in rendered image.
GPlus       = 12 : As RPlus for Green.
BPlus       = 13 : As RPlus for Blue.
RMinus      = 14 : 0 to 255 to subtract from Red in rendered image.
GMinus      = 15 : As RMinus for Green.
BMinus      = 16 : As RMinus for Blue.
DX          = 17 : 0 to ? - X amount to skip - See section parameters.
DY          = 18 : 0 to ? - Y amount to skip - See section parameters.
Start       = 19 : Starting frame number.

The values of these parameters may be set and read using the GetValue and StoreValue functions:

/* To read the value of e.g. Movement use:
   integer_variable = GetValue(Base,Movement)
*/

/* To set the value of e.g. Produce to 0 use:
   call StoreValue(Base,Produce,0)
*/

GetValue:Procedure
   Parse arg XBase, XAdd
   return C2D(IMPORT(D2C(STRIP(XBase) + (STRIP(Xadd) * 4),4),4))

StoreValue:Procedure
   Parse arg XBase, XAdd, XVal
   call EXPORT(D2C(STRIP(XBase) + (STRIP(Xadd) * 4),4),D2C(XVal,4),4)
   return

The default values passed to the script for modification are:

Movement            : (1024 * Frame)/(TotalFrames + 1) Morphs
                      (1024 * Frame)/TotalFrames       Warps

Red1,Green1,Blue1   : Movement                         Morphs
                      1024                             Warps

Red2,Green2,Blue2   : (1024 - Movement)                Morphs
                      0                 Irrelevant for Warps

Produce             : 1                                Rendered frames
                      0                 Frames 0 and TotalFrames+1
RPlus,GPlus,BPlus   : 0
RMinus,GMinus,BMinus: 0
DX,DY               : Initially set by DX and DY parameters

Changing these values allows acceleration of movement, colour fades etc. and the generation of only some images (to check a long animation).

13 Morphing algorithms

The morphing algorithm is defined using the parameters MODE and DEPTH to TSMorph-render.

The basic algorithm is to find 3 points which make a triangle around the point and morph this triangle between the start and end images.

The DEPTH parameter controls how many points will be checked to form a triangle. 0 means just the closest 3 points are examined, 1 the closest 4, 2 the closest 5 etc.

The MODE parameter controls both which triangle is chosen and what to do if no surrounding triangle is found.

If MODE=0 2 4 ... 30 (i.e. bit 1 not set [do not add 1]) then if no triangle surrounding the point is found examining the closest points then the 3 closest points are used to decide how to morph. Otherwise the point is assumed to be stationery.

If MODE=2 3 6 7 ... 30 31 (i.e. bit 2 set [add 2]) then all the closest points (the exact number controlled by DEPTH) are examined to determine the smallest triangle. Otherwise the first surrounding triangle found is used.

If MODE=4 5 6 7 12 ... (i.e. bit 3 set [add 4]) then a square algorithm is used to find the closest points. Otherwise all points are examined. Although using these MODEs could theoretically make the program run faster, it seems to generally run slower.

If MODE=8 9 10 ... (i.e. bit 4 set [add 8]) then a Delauany triangle algorithm is used to find triangles. For these modes the DEPTH parameter should normally be set to 0. Also floating point calculations are still done even if INTEGER is set to YES.

If MODE=16 17 ... (i.e. bit 8 set [add 16]) then the closest triangles are only calculated once at the start (based on the average of start and end). This should only be used if the points do not move a lot between the start and end images. It can speed things up a lot for a lot of frames. It does not make sense to use this for Animated Warps/Morphs. This uses a lot of memory:

    (DEPTH + 4) * Image_Width * Image_Height * 4

    e.g. 640x512 image, DEPTH=2 uses 7.5 MB (contiguous) memory

Therefore MODEs 0 and 1 should be faster than modes 2 or 3. The DEPTH parameter can also have a major effect on the rendering speed.

See Benchmarks.

Benchmarks

These benchmarks are based on a Morph provided by "Al Bet Sam That I’m Not Eloquent, Nancy Colours Eggs" <91016@tayloru.edu> of two 150x150 images with 41 control points.

Times are in seconds to generate the first frame on a 28MHz 68040 running in 32bit fast ram.

14 File naming

File names can include the frame number.

The format of the frame number in the file name is specified using the following formats:

%ld     : Number left justified e.g.  '1','2',..,'10',..,'123',..
%3ld    : Number right justified e.g. '  1','  2',..,' 10',..,'123',..
%03ld   : Number right justified e.g. '001','002',..,'010',..,'123',..

Where the number can be changed e.g.

pic.%04ld   for Imagine 2.0 produced files
pic%03ld    for Vista produced files
name%ld     for files to run through mpeg
