Short: A Modular Image Processing Package Author: Janne.Jalkanen@iki.fi Uploader: Janne.Jalkanen@iki.fi Version: 5.20 Type: gfx/conv PPT is a powerful, free image processing package, that boasts with the following properties: - Handles both 24 bit truecolor and 8 bit grayscale images with optional alpha channel. - Modular design, ie. you can easily add new loaders and filters to the program. - Internal multi-tasking: You can process/load/save many images at the same time! No need to wait for another project to be ready! - Unlimited (except by available memory) buffers! - Unlimited (except by available disk space) undo! - User configurable virtual memory (no MMU required) - AREXX port - Font sensitive and scalable GUI using Jan van den Baard's and Ian J. Einman's BGUI package (release 41 needed) - Quick preview window for fast updates. - Requires OS 2.0 (V37). Yes, this is a feature :) and uses some OS 3.0 (V39) features. Takes use of AGA chips if installed. CyberGFX is also supported! - Loads following image types: o IFF ILBM (1-8 bitplanes, HAM6/8, EHB, ILBM 24 bit) o JPEG/JFIF (both grayscale and 24 bit. Also progressive!) o PPM/PGM types P2, P3, P5 and P6. o PNG (all standard types) o Compuserve GIF (both 87 and 89a formats) o Targa Truevision (8,15,16,24 and 32 bit formats) o YUVN o TIFF o Anything you have a Datatype for... - Saves following image types: o JPEG/JFIF (both grayscale and 24 bit. Also progressive!) o IFF ILBM (24 bit, 1-8 bitplanes) o PPM/PGM types P5 and P6 o PNG (grayscale and 24 bit) o Compuserve GIF (both 87 and 89a formats) o Targa Truevision (24 bit) o C-code - Can do several effects (over 30 effects): o AutoCrop & Crop o Flip, Shift, Roll o Colorspace manipulations o Convolute (User-definable masks up to 7x7 size supported! Many example masks included. Saving and loading custom masks.) o Remove Isolated Pixels o Histogram Equalization (local & global) o Brightness, contrast & gamma correction o Threshold o Scale & Resize o Image compositing o Noise (many variations) o Color manipulation (ColorMix, ColorChange, Extract) o and many others...

Changes from the C-3 release include: ---snip--- Version 4.61 (Sunday, 25-Oct-98 22:46:56) ----------------------------------------- - Added Contrib-directory to the distribution and made PPT seek modules from there - Info now shows also which CPUs the current effect/iomod supports Version 4.62 (Sunday, 08-Nov-98 00:53:30) ----------------------------------------- - Major changes in localization - now it should even be possible... =) - Bug fix: AREXX IOMODULEINFO did not handle save formats correctly - AREXX IOMODULEINFO now returns a new stem item: PREFERREDPOSTFIX - File requesters now remember their positions (if you use Preferences/Save) - Bug fix: REXX error messages did not arrive correctly, if loading failed. Version 4.63 (Friday, 04-Dec-98 23:18:18) ----------------------------------------- - GIF.iomod 1.6: Fixed bug with certain image types not loading, but failing with error "EOF detected". Reported by Detlef Wojtaszkiewicz.

Version 5.0 (Wednesday, 09-Dec-98 22:23:08) ------------------------------------------- - THE API HAS CHANGED! You must remove any modules you had, since they do not work anymore with V5. For the technically minded people: PPTBase moved from a5 to a3, since it was causing problems with GCC. It was a stupid idea to begin with, I admit. Should've done my research better...

Version 5.7 (Sunday, 20-Dec-98 19:21:36) ---------------------------------------- - Rewrote almost all toolbar handling (it is now almost a proper BGUI class) - Added new PPT icons courtesy of A.

Version 5.15 (Sunday, 14-Feb-99 19:42:01) ----------------------------------------- - Bug fix: no longer opens and closes display if there is no need when you change prefs. - Added support for preview dithering.

Version 5.17 (Saturday, 20-Feb-99 12:21:16) ------------------------------------------- - For some strange reason, I kept linking with v40.14 of amiga.lib, causing memory pools to malfunction under OSV37.
