Graphics32 1.8.3

Graphics32 is a library designed for fast 32-bit graphics handling on Delphi and Kylix.
Optimized for 32-bit pixel formats, it provides fast operations with pixels and graphic primitives,
and in most cases Graphics32 outperforms the standard TCanvas classes.
It is almost a hundred times faster in per-pixel access and about 2–5 times faster in drawing lines.


Features
Some of Graphics32 features include:

• Fast per-pixel access up to 100 times faster compared to standard TBitmap;
• High-performance Bitmap alpha blending (including per-pixel alpha blending);
• Pixel, line and polygon antialiasing with sub-pixel accuracy (combined with alpha blending);
• Arbitrary polygon transformations and custom fillings;
• Bitmap resampling with high quality reconstruction filters (e.g. Lanczos, Cubic, Mitchell);
• A unique state-of-the-art rasterization system;
• Affine transformations of bitmaps: rotations, scaling, etc with sub-pixel accuracy;
• Arbitrary projective transformations of bitmaps;
• Arbitrary remapping transformations of bitmaps (e.g. for Warping, Morphing);
• Flexible supersampling implementation for maximum sampling quality;
• Flicker-free image displaying components with optimized double buffering via advanced MicroTiles based repaint optimizer;
• Multiple customizible easy-to-use overlay layers;
• Locking of bitmaps for safe multithreading;
• A property editor for RGB and alpha channel loading;
• Design-time loading of image formats supported by standard TPicture;
• Works on Borland Delphi, C++ Builder and Kylix.

Notes:
Team Graphics32 is happy to announce the release of Graphics32 version 1.8.3. This version is a bugfix release of the 1.8.2 revision.


Changes: 1.8.3
Additions
---------
* Added new ASM/(E)MMX optimized ApplyBitmask routine for logical (bitwise) Xor/Or/And operations using a bitmask.
* Added new TColor32Component basetypes for specifying a component or component sets (related updates to TColor32Entry).
* Added new CopyComponents routine for copying selected ARGB components btwn bitmaps.

Optimizations
-------------
* Optimized TBitmap32.ResetAlpha, Invert and InvertRGB.
* Optimizations in pamTransparentEdge related routines.
* TPatternSampler now supports nonrectangular sampling patterns.

Bugfixes
--------
* Bugfix in MMX version of BlockAverage that caused access violations on resampling.
* Fixes for the following bugs reported on the SourceForge tracker: 1560912, 1556318
* Fixed misbehvior when setting TCustomImage32.BufferOversize property. Changes now directly force resizing of the buffer.
* Fixed Kylix compilation issue introduced with new multithreading support.
* Several minor cleanups and fixes.
