<p>This function takes a slice of bytes and writes the pixel data of the image into it.
|
|
The rectangle is specified by the x and y coordinates of the top left corner, the width
|
|
and height of the rectangle, and the row pitch of the buffer. The row pitch is the number
|
|
of bytes between the start of one row and the start of the next row. The row pitch must be
|

at least as large as the width of the rectangle in bytes.</p>
