Method
VipsImageget_tile_size
Declaration [src]
void
vips_get_tile_size (
VipsImage* im,
int* tile_width,
int* tile_height,
int* n_lines
)
Description [src]
Pick a tile size and a buffer height for this image and the current
value of vips_concurrency_get(). The buffer height
will always be a multiple of tile_height.
The buffer height is the height of each buffer we fill in sink disc. Since we have two buffers, the largest range of input locality is twice the output buffer size, plus whatever margin we add for things like convolution.
