Module vizia::vg::color_filters

Functions

• blend
• blend_with_color_space
  Blends between the constant color (src) and input color (dst) based on the BlendMode. If the color space is None, the constant color is assumed to be defined in sRGB.
• compose
• hsla_matrix
  See hsla_matrix_of_color_matrix()
• hsla_matrix_of_color_matrix
• lerp
• lighting
  Create a color filter that multiplies the RGB channels by one color, and then adds a second color, pinning the result for each component to [0..255]. The alpha components of the mul and add arguments are ignored.
• linear_to_srgb_gamma
• matrix
• matrix_row_major
• srgb_to_linear_gamma
• table
  Create a table color filter, copying the table into the filter, and applying it to all 4 components. a' = table[a]; r' = table[r]; g' = table[g]; b' = table[b]; Components are operated on in unpremultiplied space. If the incoming colors are premultiplied, they are temporarily unpremultiplied, then the table is applied, and then the result is re-multiplied.
• table_argb
  Create a table color filter, with a different table for each component [A, R, G, B]. If a given table is None, then it is treated as identity, with the component left unchanged. If a table is not None, then its contents are copied into the filter.
• table_from_color_table
  Create a table color filter that holds a ref to the shared color table.
