Short: application layer for pixel graphics Author: Timm S. Müller Type: dev/misc Version: 20.0 Requires: os3.x (v39) or MorphOS 1.x or AmigaOS4, render.library overview ----------------------------- - guigfx.library is an application layer for pixel graphics. - guigfx.library breaks the chains of all those nasty planar, chunky, 8/16/24bit, OS3.0, OS3.1, OCS, ECS, AGA, CybergraphX and Picasso96 considerations. - with guigfx.library you no longer have to take care about your application running on a OCS machine or on a high-end graphics-card system. - guigfx.library lets you freely choose truecolor graphics for your applications. - with guigfx.library your graphics will always look as fine as possible, on any screen, no matter if driven on 24 bit 1024x768 CybergraphX/Picasso96, on HAM8, or 1 bit productivity interlaced. - guigfx.library does quick color-reduction, rendering, remapping and dithering for you. only you don't know when, on which machine, under what circumstances. - guigfx.library treats scaling as a standard operation. it is available at any time, without extra consideration, without extra memory consumption, even without a true loss of performance. - guigfx.library handles screen pen allocation in an extremely effective way. - guigfx.library hides bugs, incompatibilities and insufficiencies of graphics.library, cybergraphics.library and Picasso96 from you. it is an attempt to render incompatibilities between different versions of CybergraphX and Picasso96 obsolete. - guigfx.library features picture.datatype import. standard and v43 (including Picasso96) picture datatypes are automatically recognized and used as available. - guigfx.library does not call SetFunction() and is hereby guaranteed to never do so in future versions. - guigfx.library puts all that stuff into a black-box, freeing your mind for the creative part. features ----------------------------- - full truecolor, OCS, ECS, AGA, HAM support - screen-pen management - color-reduction - dithering - picture.class datatype import - scaling - image processing methods (crop, scale, render, tint, alpha-channel, texture-mapping, ...) - fully documented - supplied with C includes for SAS/C, StormC and MaxonC - freeware requirements ----------------------------- - render.library v30 - os3.x (v39) optional: - higher OS, higher CPU, FPU - CyberGraphX or Picasso 96 - MorphOS - AmigaOS4 recent changes ----------------------------- v20.0.2 [16-Mar-05] - fixed wrong modulo value in two WritePixelArray() calls; fixed only in the OS4 version as the wrong value is harmless under MorphOS and OS3.x (reported by Stephan Rupprecht) v20.0 [03-Mar-05] - added AmigaOS4 binary and includes; compiled by Andreas Falkenhahn v20.0 - added picture attributes PICATTR_NumPaletteEntries and PICATTR_Palette to GetPictureAttrs(). This way you can query a picture's palette. PICATTR_NumPaletteEntries will currently always return 256 if a picture is palette-based, and zero otherwise. PICATTR_Palette expects a buffer of 256 ULONG entries in (by default) the format PALFMT_RGB8. Requested by Andreas Falkenhahn. v19.2 - when a picture was read from a hicolor/truecolor rastport using ReadPicture(), a palette was incorporated to the picture. ClonePicture() created a copy of that palette but did not actually place it in the resulting picture. when the library was closed, the leak was indicated with a ILLEGAL exception. fixed. v19.1 - fixed a LOOONG standing bug when adding pictures to a pensharemap, when the picture was less than 7 lines high. ouch!
