ImagingUtil

Description

static class Tinman.Terrain.Imaging.ImagingUtil

Helper class for working with image files.

Public / Constants

Gamma​From​Srgb

public constant GammaFromSrgb → (-2.2:float64)

Special gamma correction value for the sRGB color space (see IImageInfo.Gamma).

Color space decompression for sRGB can be approximated with the exponent 2.2. The full formula is implemented in ColorF.FromSrgbF.

Gamma​To​Srgb

public constant GammaToSrgb → (-0.45455:float64)

Special gamma correction value for the sRGB color space (see IImageInfo.Gamma).

This is the same value that is found in the gAMA chunk of sRGB compressed PNG files.

Public / Methods

Bad​Format
