Description

The GR32_Transforms unit provides a comprehensive framework for spatial coordinate transformations, bitmap resampling transformations, vector path warp operations, and geometric projections in Graphics32.

It includes:

• Base class hierarchy (TTransformation, TNestedTransformation, T3x3Transformation).
• Linear 2D affine operations (TAffineTransformation) for rotation, scaling, translation, and skewing.
• Projective quadrilateral mapping (TProjectiveTransformation and TProjectiveTransformationEx).
• Non-linear spatial warps and distortions (twirl, bloat, disturbance, fish-eye, polar, radial distortion, vector remap, path warp, and sphere projection).
• Low-level $3\times 3$ floating-point and fixed-point matrix algebra routines.
