Graphics32

Optimized for 32-bit pixel formats, it provides fast operations with pixels and graphic primitives.

Graphics32 considerably outperforms the standard TBitmap/TCanvas methods.

It is almost a hundred times faster in per-pixel access and about 2–5 times faster in drawing lines.

Features:

• 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.

What is new in this release:

• 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.
