Detailed Description

A paint device contains the actual pixel data and offers methods to read and write pixels.

A paint device has an integer x,y position (i.e., are not positioned on the image with sub-pixel accuracy). A KisPaintDevice doesn't have any fixed size, the size change dynamicaly when pixels are accessed by an iterator.

virtual

Copy the bytes in data into the rect specified by x, y, w, h.

If the data is too small or uninitialized, Chalk will happily read parts of memory you never wanted to be read.

If the data is written to areas of the paint device not previously initialized, the paint device will grow.
