Abstract
There are provided systems and methods for tinting an image by monochromatic tinting using saturation maps for use by an application providing a user interface supporting customizable tinted images. By using saturation map and a monochromatic value map derived from the image and configuring the saturation map to specify areas for tinting, a tint color can be applied to the image by a series of quickly processed arithmetic calculations. This provides a lightweight and high quality method for tinting images within an application without wasting unnecessary network bandwidth or processor resources. Furthermore, the method can be adapted to apply multiple tint colors for multiple tints or use an alpha channel to restore color information lost due to the monochromatic value map. The resulting tinted image can also be used as a texture for a three-dimensional rendering engine.
