METHOD AND SYSTEM FOR IMPLEMENTING FLEXIBLE COLOR SCHEMES IN A RASTER IMAGE
First Claim
1. A method for coloring a greyscale raster image defined by a plurality of predefined greyscale values, said method being implemented on at least one computing device having non-transitory computer-readable storage medium with an executable program stored thereon, said method comprising the steps of:
- executing the program stored on the computer-readable storage medium, wherein the program instructs the at least one computing device to;
receive a color selection intended for a portion of the raster image;
retrieve from a predefined database multiple groups of predefined color parameter values, each group of predefined color parameter values defining a color parameter associated with the selected color;
for each pixel within said portion of said raster image, determine a pixel channel value for each of a plurality of color channels that collectively define a color of said pixel, said determination being based on said predefined greyscale value for said pixel, and said predefined color parameter values for at least two of said predefined color parameters associated with said selected color.

Abstract
A method for coloring a greyscale raster image defined by a plurality of predefined greyscale values, having the following steps: (i) receiving a color selection intended for a portion of the raster image; (ii) retrieving from a predefined database multiple groups of predefined color parameter values, each group of predefined color parameter values defining a color parameter associated with the selected color, and each group of predefined color parameter values including a predefined greyscale value; and (iii) for each pixel within said portion of said raster image, determining a pixel channel value for each of a plurality of color channels that collectively define an appearance of said pixel, said determination being based on said predefined greyscale value for said pixel, and said predefined color parameter values for at least two of said predefined color parameters associated with said selected color.

-
executing the program stored on the computer-readable storage medium, wherein the program instructs the at least one computing device to; receive from a user a color selection intended for a portion of the raster image; retrieve from a predefined database multiple groups of predefined CMYK values, each group of predefined CMYK values defining a color parameter associated with the selected color; calculate a group of CMYK values for a pixel within said portion of the raster image by interpolation based on said greyscale value for said pixel and said predefined CMYK values for at least two of said predefined color parameters associated with said selected color. - View Dependent Claims (10, 11, 12)
