Gamma-aware, dithered colorspace conversion and resizing

[PhrostByte]

Hello all, I've made a new filter that performs gamma-corrected colorspace conversion and Spline36 resizing in a single function.

Download version 8 for 32-bit:

Usage:

ResampleHQ(clip
           [, int width]
           [, int height]
           [, string dstcolorspace]
           [, string srcmatrix]
           [, string dstmatrix]
           [, bool dither]
           [, float src_left]
           [, float src_top]
           [, float src_width]
           [, float src_height]
           [, string kernel]
           [, float karg1]
           [, float karg2]
           [, float kblur_x]
           [, float kblur_y]
           [, string chroma_kernel]
           [, float chroma_karg1]
           [, float chroma_karg2])

Too many settings to list here, see documentation above for what they all do.

Note: Dithering YV12 and YUY2 output is not currently supported and will come at a later version. Interlaced formats are also not supported.

Here's an example from Avisynth's gamma-ignorant Spline36Resize:



And now here's the gamma-aware ResampleHQ version:



Note how the ResampleHQ image is much brighter overall, and shows faint light in completely new places around Canada, Alaska, western United States, and along coastlines.

This image was cherry-picked to show how off Avisynth's resizers can be with sharp contrast. Most video will show far less improvement.
