A pixel buffer is an array of pixel data that can be applied in bulk, or 'blit'ed, to the frame buffer. Pixel buffers may be of a different color mode and will be converted to match the destination frame buffer before application. This version can resize the source data before blitting. The option GFXF_RESIZE_METHOD selects the resize technique.
LIB_EXPORT GFX_Result GFX_DrawStretchBlit( GFX_PixelBuffer* buffer, int32_t src_x, int32_t src_y, int32_t src_width, int32_t src_height, int32_t dest_x, int32_t dest_y, int32_t dest_width, int32_t dest_height );

Description |
|
buffer |
the pointer to the source pixel buffer |
|
src_x |
the x component of the rectangle of the buffer to blit, usually 0 |
|
src_y |
the y component of the rectangle of the buffer to blit, usually 0 |
|
src_width |
width of the rectangle of the buffer to blit, usually the entire with of the source buffer |
|
src_height |
height of the rectangle of the buffer to blit, usually the entire height of the source buffer |
|
dest_x |
the x position to blit the source rectangle in the destination buffer the y position to blit the source rectangle in the destination buffer |
|
dest_width |
the desired resize width |
|
dest_height |
the desired resize height |
GFX_Result - Returns GFX_TRUE if the blit was drawn successfully. Otherwise returns GFX_FALSE.
