set_region

Description:

public Bool set_region (int src_x, int src_y, int dst_x, int dst_y, uint dst_width, uint dst_height, int width, int height, PixelFormat format, uint rowstride, uint8 data)

Sets the pixels in a rectangular subregion of this from an in-memory buffer containing pixel data.

<note>The region set can't be larger than the source data</note>

Parameters:

this	a Texture.
src_x	upper left coordinate to use from source data.
src_y	upper left coordinate to use from source data.
dst_x	upper left destination horizontal coordinate.
dst_y	upper left destination vertical coordinate.
dst_width	width of destination region to write. (Must be less than or equal to `width`)
dst_height	height of destination region to write. (Must be less than or equal to `height`)
width	width of source data buffer.
height	height of source data buffer.
format	the PixelFormat used in the source buffer.
rowstride	rowstride of source buffer (computed from width if none specified)
data	the actual pixel data.

Returns:

true if the subregion upload was successful, and false otherwise
