I have a bitmap that I load from a file and put into an integer array. To do this I draw the bitmap onto a canvas and then uses the canvas' pixels property to get the pixels into the array. The problem is it won't work if the canvas isn't a part of a VCL. When I made a variable of type TCanvas, and tried to draw the bitmap onto it I got a error message saying something like "Canvas does not allow drawing!". Everything worked fine when I drew onto the canvas of a TImage. What am I doing wrong? Is there a better way to do this without using the canvas?
