Short: A Modular Image Processing Package Author: Janne.Jalkanen@iki.fi Uploader: Janne Jalkanen iki fi Type: gfx/conv Version: 6.18 Architecture: m68k-amigaos [ Note from the Aminet administrator: this release is from February 2000, ] [ uploaded to Aminet to replace the even older version we still had online ] 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 Targa Truevision (8,15,16,24 and 32 bit formats) o YUVN o TIFF o Psion PIC format o Windows & OS/2 BMP 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 Targa Truevision (24 bit) o Psion PIC format o C-code o Windows & OS/2 BMP - 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... This release of PPT is called "Descartes" to honor the great French mathematician and philosopher. Changes from the C-6 release include: ---snip--- Version 5.21 (Thursday, 25-Feb-99 20:22:07) ------------------------------------------- - ColorChange 1.9: Fixed a buffer overflow, causing Mungwall hits occasionally. Really BGUIs fault. Version 5.22 (Saturday, 27-Feb-99 22:07:55) ------------------------------------------- - Added a new iomodule: Psion PIC. Version 5.23 (Saturday, 13-Mar-99 17:35:24) ------------------------------------------- - Preview windows now look at font height when deciding where to open. - Allowed patterns in all file requesters. Both reported by J-P LeBel. Version 5.24 (Saturday, 13-Mar-99 18:03:27) ------------------------------------------- - Bug fix: If a file had a wrong suffix, it would not be recognized correctly. (Reported by J-P LeBel) Version 5.25 (Sunday, 14-Mar-99 21:04:02) ----------------------------------------- - Some cosmetical changes - ASL file requesters now remember their position (a bug in BGUI, but could be worked around) - Speeded up select box handling (still not as fast as I'd like, most of the time is consumed in updating the select window gadgets - It's no longer possible to edit a palette if the image has not yet been rendered (a workaround to a bug in BGUI). - Save As now checks if the file already exists and warns you before it deletes it. (Suggested by Uwe Pannecke). Version 5.26 (Wednesday, 17-Mar-99 23:56:35) -------------------------------------------- - Updated the speed of the select box once more by cutting down the selection area refresh rate. Tell me if this is a problem. - Scale.effect v1.8: Now contains quick doubling and halving gadgets. Also fixed a few minor bugs. Suggested by several people. Version 5.27 (Sunday, 28-Mar-99 23:53:59) ----------------------------------------- - PsionPIC 1.1: Saving added. Version 5.28 (Wednesday, 31-Mar-99 13:30:44) -------------------------------------------- - Preferences are now saved on exit, unless you use "Quit, lose changes." - Added start-up tips. - Render screens now have a title for screen commodities, etc. Version 5.29 (Sunday, 30-May-99 18:18:52) ----------------------------------------- - Reworked the entire selection system to accommodate new selection modes.
