- View V2.0 - 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. You can also view
- RGB Raw (Sculpt), or Pro RGB files. 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 2.0 supports IFF ANIM OpCode 5 animations. This is the
- standard ANIM format that has been adopted by the Amiga
- community. Old animations from VideoScape, & HASH Enterprises
- may NOT be OpCode 5. Some ANIM and ILBMs have non-standard
- methods of filling the Bitmap Header structure. Meaning that the
- values are not what View or other viewers expect. This is very
- unfortunate and impossible to detect. Therefore View will ignore
- the questionable values and insert the values that are set in the
- users preferences. This way ALL pictures and animations will be
- centered onto your display (that is if your preferences places
- your WorkBench screen into the center of your monitor's display).
- This also is useful for those of you that have Flicker-Fixers
- connected.
-
- OpCode-6 Animation is my own creation and has not been
- recognized as a standard IFF ANIM format by Commodore. 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).
- Once I hear from Commodore the OpCode may or may not change
- depending on whether OpCode 6 has been taken already, so don't
- write any code that may depend on it. There is a problem
- inherent in this QUAD buffering technique! The problem is in the
- fact that standard Amigas only have 512K of CHIP ram, and some is
- taken for the workbench screen. But since you probably haven't
- got an animation that is Op-Code 6 (since I haven't released any
- yet, and 3D Professional isn't out yet to make your own) these
- problems are not yours. I will attempt to do some memory magic
- to require only 2 of the four bitmaps to be in chip ram at one
- time. But I have a feeling that this will cause the animations
- to slow down, due to data swapping that may or may not need to be
- done.
-
- 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.
-
-
- VIEWING CONTROLS:
-
- <ESC> stops viewing for an animation or picture.
-
- <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).
-
-
-
-
- To view RGB pictures simply select the file to view. If it is
- a Raw-RGB file it must use the standard ".red", ".grn", ".blu"
- extensions. You will be prompted for an input resolution and an
- output format. If the RGB file is in Pro-RGB format the input
- resolution can not be modified. Once the output format has been
- selected you can click on the "SHOW", "SAVE", or "CANCEL" buttons.
- If you select "SAVE" the picture will be shown and when you press
- the <ESC> key you will be prompted for a filename to save with.
- If you are not sure whether you wish to save the picture or not
- select the "SHOW" button. After viewing the picture pressing the
- "S" key will save the picture.
