Description

Copies a region of pixels from the display window to another area of the display window and copies a region of pixels from an image used as the srcImg parameter into the display window. If the source and destination regions aren't the same size, it will automatically resize the source pixels to fit the specified target region. No alpha information is used in the process, however if the source image has an alpha channel set, it will be copied as well.

This function ignores imageMode().
