Description

The GR32_Resamplers unit implements high-performance image resampling, spatial filtering, neighborhood sampling, and block transfer operations in Graphics32.

It includes:

• Resamplers: Fast nearest-neighbor (TNearestResampler), bilinear (TLinearResampler), draft downscaling (TDraftResampler), and high-quality arbitrary kernel resampling (TKernelResampler).
• Spatial Reconstruction Kernels: A comprehensive collection of filter kernels including Box (TBoxKernel), Triangle/Linear (TLinearKernel), Cosine (TCosineKernel), B-Spline (TSplineKernel), Mitchell-Netravali (TMitchellKernel), Keys Cubic (TCubicKernel), Hermite (THermiteKernel), Sinsh (TSinshKernel), Gaussian (TGaussianKernel), and Windowed-Sinc kernels (TAlbrechtKernel, TLanczosKernel, TBlackmanKernel, THannKernel, THammingKernel).
• Nested Samplers & Coordinate Transformers: Sampler chaining via TNestedSampler, coordinate transformation via TTransformer, uniform TSuperSampler, and recursive adaptive TAdaptiveSuperSampler.
• Neighborhood & Morphological Samplers: Discrete convolution (TConvolver), bilateral/selective convolution (TSelectiveConvolver), morphological dilation (TDilater), erosion (TEroder), expansion (TExpander), and contraction (TContracter).
• Block Transfer Functions: High-performance unscaled (BlockTransfer, BlockTransferX, BlendTransfer) and scaled (StretchTransfer) bitmap transfer routines.
