) |
| | |
Update a sub-rectangle of the image from an array of pixels.
Warning: for performances reasons, this function doesn't perform any check; thus you're responsible of ensuring that rectangle does not exceed the image size, and that pixels contains enough elements.
- Parameters:
-
| rectangle | : Sub-rectangle of the image to update |
| pixels | : Array of pixels to write to the image |
