The RGB color model is an additive color model based on the human eye perception of colors. It uses transmitted light to display color and consists of three components: red (R), green (G) and blue (B). These components are the amounts of red, green, and blue light measured in values ranging from 0 to 255, and they are combined in varying intensities to produce all other colors in the RGB color model. When the value of each component is 255, the color white displays; when the value of each component is 0, the result is pure black. If the processed image is a 16-bit-per-channel one, the range of the RGB values is extended to 0-65535. During the merge or split operation ImageWarp simply combines pixel values into RGB triplets or splits the triplets into separate images without applying any recalculation. The processing algorithms are applied to each individual component independently.
