#include <vips/vips.h>int
im_grid( IMAGE *in, IMAGE *out,
int tile_height, int across, int down )
Description
im_grid(3) slices image in into a set of tiles, each the same width as in and of height tile_height and rearranges the tiles into a grid with across tiles across and down tiles down.It is useful for loading volumetric images (for example, CT or PET scans) where more than 2 dimensions need to be displayed.
The current implementation is optimised for the case where image in is thin and tall and across and down are large.
