Module rsvg::surface_utils::srgb

Utility functions for dealing with sRGB colors.

The constant values in this module are taken from http://www.color.org/chardata/rgb/srgb.xalter

Constants

• LINEARIZE 🔒
• UNLINEARIZE 🔒

Functions

• linearize
  Converts an sRGB color value to a linear sRGB color value (undoes the gamma correction).
• linearize_surface
  Converts an sRGB surface to a linear sRGB surface (undoes the gamma correction).
• map_unpremultiplied_components 🔒
  Applies the function to each pixel component after unpremultiplying.
• map_unpremultiplied_components_loop
  Processing loop of map_unpremultiplied_components. Extracted (and public) for benchmarking.
• unlinearize
  Converts a linear sRGB color value to a normal sRGB color value (applies the gamma correction).
• unlinearize_surface
  Converts a linear sRGB surface to a normal sRGB surface (applies the gamma correction).
