Let say i have single channel image (2d matrix) with some width and height and with limited range integer values, lets say 0..14.
I want to display this image/matrix on screen, but each value should be colored with custom predefined color (i.e color map/pallete).
What is the best/efficient way to do it in Kotlin/Java?
Do i manually need to do the conversion from single channel to rgb bitmap? or maybe there is already a control that display the matrix as is with option to specify custom pallete? Is there any native that do it?
