Abstract: Examples of memory-efficient techniques for dynamically generating images having customizable image portions are disclosed herein. In particular embodiments, a collection of contributing images with different image information in the contributing image's channel layers is used to generate a composite result image. By combining the subimage data from each channel of the contributing image in accordance with a composite image function, a resultant composite image can be generated that has the desired customized properties selected by the user. To create the customized properties, one or more of the color channel subimages can have their values scaled (e.g., using matrix multiplication) according to the customization preferences of the user such that, when combined with the other contributing images, the desired customized result is presented to the user.
