View V3.2 - ANIM/ILBM Viewer
View is a program that allows you to view all ANIM opcode 5 or
6 animations and all ILBM IFF format pictures. This viewer
program is freely re-distributable. This means that you may
distribute it to anyone, or anywhere that you so desire providing
that this unaltered file, and the original unmodified program are
distributed together.
------------------------------------------------------------
View 3.0 supports IFF ANIM OpCode 5 animations. This is the
standard ANIM format that has been adopted by the Amiga
community.
OpCode-6 Animation is my own creation. The format is exactly
the same as OpCode 5 but is QUAD buffered instead of DOUBLE
buffered. This allows the player to show 2 screens at one
time for the X-Specs Glasses. Each picture MUST be viewed for
1/60th of a second, therefore to see a 3D-Picture the viewer can
only play ANIMs at 30 frames per second. (2 pictures = 1 frame).

-------------------------------------------------------------
Updated from versions 2.0/2.1:
1. RGB file support has been removed. It proved to be too bulky
and widely unused. And I personally never used it.
2. The code has been significantly reduced. Mostly because of the
removal of RGB support.
3. A bug was fixed that made some IFF pictures display incorrectly.
4. Another bug with HIRES OVERSCAN animations has been fixed.
5. The method for positioning the display has changed AGAIN.
It was found the DCTV pictures had problems with the last method
that I used.
6. A new interface has been applied. This means a new file
requester, (with all the features of the old one plus a few more).
As well as the fact that the file information is now readable on
the screen. The key sequences are displayed view a help screen.
***********
Updated from versions 3.0 to 3.2:
1. AGAIN the method for positioning the display has been changed,
to accomodate DCTV pictures. This 'should' be the final needed change.
2. The menus have been removed when in the 'HELP' or 'ABOUT' screens.
The menus are not affected anywhere else.
3. Support for brushes has been added. A brush is any IFF picture
that is SMALLER than the default resolution for its display mode.
4. Support for ANIM brushes was added. Since ANIM brushes have an
interleave of one, double buffering required copying the buffer every
animation frame. This gets rid of flicker but may reduce the speed at
which the brush plays. I tried the brushes I have, however, and could
not detect any speed decrease. Thus I decided to double buffer the ANIM
brush for flickerless playback.
5. I Added an options menu. This menu currently holds only one item.
"Pause on entry", when turned on (CHECKED) it will cause the animation
to begin in paused mode. To start the animation playing, press the <SPACE>
key.
6. View 3.0 did not support non-looping animations correctly. The
routines that were uses in versions 2.x had a bug. I changed the program
so that these animations would work, but non-looping animations would not
play without a small -hiccup- upon reaching the end of the animation. This
version of the program now properly handles non-looping animations. It
does this by detecting the non-looping animation and adding the loop frames
magically transforming it into a looping animation.
-------------------------------------------------------------
The programs execution should be fairly easy to understand. To
view a single animation or picture either run view from CLI
passing it the filename, or click onto the PROJECT icon of the
file.
Example: if desired ANIM is named "foo.anim"
<CLI> 1> view foo.anim
<WORKBENCH> double click the "foo.anim" icon. The icon
MUST be a project type icon, with its DEFAULT
TOOL set to point to the View
program.
To view multiple animations or pictures simply run the view
program with no arguments. A file requester will appear and you
may select a file. After viewing the picture or animation the
file requester will reappear.
When you have seen enough click on the CANCEL gadget in the file
selector.
Example:
<CLI> 1> view
<WORKBENCH> double click the "VIEW" icon.
Another method for viewing multiple files is :
<CLI> 1> view <file1> [file2] [file3] [...]
<WORKBENCH> single click or drag select multiple project icons
and double click on the last one with the <SHIFT>
key pressed.
-------------------------------------------------------------
Version 3.0 now has menus. This allows for a help menu so that you
have to remember the keys listed below.
VIEWING CONTROLS:
<ESC> stops viewing for an animation or picture.
<LEFT> mouse buttone also stops viewing.
<ARROWS> move the view offsets of the picture or
animation.
<FUNCTION KEYS> change the playback speed of the animation.
<RETURN> Default speed. This will use the timing
information in the
ANIM file for its speed. This option is DEFAULT
on.
<SPACE> Freezes the animation at the current frame.
<a> Advances forward one frame. (must first freeze it of
course).
