Brief Note On Viewtek 1.05
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Viewtek 1.05 was distributed with the ImageFX 1.5 release. Think of it
as sort of a precursor to this version. It was not a complete Viewtek
release. Please distribute this version instead of 1.05.
Introduction
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Viewtek is an picture and animation viewer utility designed for Workbench
2.0 and up. It started out as a pretty simple project, but naturally it's
developed into a large shambling behemoth of a program (well, sort of).
Quickstart
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
From Workbench: Double-click the VT program icon, and select one or
more files from the resulting file requester to view images or animations.
From CLI: Type VT followed by one or more image files or directories.
Use the left mouse button to proceed to the next image when viewing a
batch of images.
Viewing Commands
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ESCAPE Abort viewing immediately.
BACKSPACE Abort viewing current directory (when using 'ALL').
LMB/RMB Go to next picture (unless using the 'NOCLICK' option).
SPACE Will hold on the current picture, when using DELAY.
S Will save the currently displayed picture as an
ILBM (you will be asked for an output filename).
This only works on pictures; not animations (yeah,
I know it would be nice to save frames from anims,
but gimme a break here... I've only got 2 hands. :)
ANY KEY Go to next picture.
CTRL+Arrows Move image/anim around on the display (overscan position).
Up Arrow (Anim Only) Return to beginning of the animation.
Right Arrow (Anim Only) Pause/single step animation.
Down Arrow (Anim Only) Resume playing animation after paused.
C (Anim Only) Toggle "continuous" mode.
F1 (Anim Only) Play animation as fast as possible.
F2 (Anim Only) Play animation at 60fps.
F3 (Anim Only) Play animation at 30fps.
F4 (Anim Only) Play animation at 24fps.
F5 (Anim Only) Play animation at 15fps.
F6 (Anim Only) Play animation at 12fps.
F7 (Anim Only) Play animation at 10fps.
F8 (Anim Only) Play animation at 5fps.
F9 (Anim Only) Play animation at 1fps.
F10 (Anim Only) Play animation at rate specified in ANIM file.
Useage From CLI
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Viewtek generally works better from CLI (assuming you can type), since you
have more options immediately available to you.
The basic syntax is:
VT [options] <one or more files or directories>
Typing VT ? will give you a brief, jumbled display of all available
options like so:
Files/M,AL=All/S,BU=BufSize/K/N,CF=Config/K,CL=Clip/S,CO=Cont/S,
DE=Delay/K/N,DF=Default/S,DI=Disk/S,DT=DataTypes/S,FO=Forever/S,
FP=FPS/K/N,HD=Hide/S,HI=Hires/S,IC=Iconify/S,IL=ILBM/S,IN=Info/S,
LA=Lace/S,LM=LowMem/S,LO=Lores/S,LP=Loop/K/N,MA=MaxFrames/K/N,
NB=NoBusy/S,NC=NoClick/S,ND=NoDisk/S,NL=NoLace/S,NS=NoScroll/S,
NT=NTSC/S,PA=Paused/S,PL=PAL/S,PO=Pointer/S,QU=Quiet/S,RE=Repeat/K/N,
S7=Super72/S,SA=Save/K,SC=ScreenMode/K,SP=Speed/K/N,SU=SuperHires/S,
UN=UnderScan/S,UT=Unit/K/N:
See "Option Keywords" below for details about all available options.
Useage From Workbench
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Viewtek may be run from Workbench in several ways.
1) Double-clicking on the Viewtek icon will bring up a requester asking
for one or more files to view.
2) You may use extended selection to highlight several picture or
animation icons and, while holding shift, double-click on the Viewtek program
icon. The files selected will be shown.
3) You may set Viewtek as the default tool for any picture or animation
icon.
See "Option Keywords" below for tool types that you may use in either
the Viewtek icon or any picture project icon.
Option Keywords
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
These options are available on the CLI command line, via. Workbench
tool types, or in the configuration file. Note that the abbreviations
only work on the CLI command line; you must spell the options out from
Workbench or in the configuration file.
File Handling Options
~~~~~~~~~~~~~~~~~~~~~
Files/M (CLI only)
One or more files, directories, or patterns. If you give VT a
directory, all files in that directory will be shown (in no
special order). Standard AmigaDOS wildcards are supported.
Basically, anything that is not a recognizable option is assumed
to be a file spec.
AL=All/S
Tells VT to recursively enter subdirectories.
CL=Clip/S
Read image from clipboard.
DE=Delay/K/N
Number of seconds to show each picture or animation before
automatically proceeding to the next one. The timer doesn't
start until *after* the picture or animation has been loaded.
DT=DataTypes/S
Force VT to use Datatypes to identify and display files (normally
datatypes is the last thing checked before giving up on a file).
This lets you, for example, use a datatypes GIF converter instead
of the one built into VT.
DefaultDir/K (Workbench or Configuration File only) (2.0)
Specify the directory where Viewtek will open its initial
file requester.
FO=Forever/S
Repeat showing the list of files given on the command line
forever and ever amen (and/or until cancelled).
IL=ILBM/S
Force VT to assume all files are ILBM pictures. In case you only
want to show the first frame of an animation and not the whole
thing.
NC=NoClick/S (2.0)
Disable the standard method of using the mouse buttons to
skip to the next picture. With this option enable, you will
have to use the keyboard.
RE=Repeat/K/N
Repeat showing the list of files given on the command line
the number of times specified (or until cancelled manually).
SA=Save/K
Save the resulting image that VT renders to a displayable
ILBM file. Makes VT into a (*very*) simple file conversion
utility. (NOTE: I have no plans to turn VT into a killer
awesome amazing wonderful convert-anything-to-everything-
else file converter.)
UT=Unit/K/N
Specify clipboard unit when showing contents of clipboar
