Method
VipsImagegrid
Declaration [src]
int
vips_grid (
VipsImage* in,
VipsImage** out,
int tile_height,
int across,
int down,
...
)
Description [src]
Chop a tall thin image up into a set of tiles, lay the tiles out in a grid.
The input image should be a very tall, thin image containing a list of
smaller images. Volumetric or time-sequence images are often laid out like
this. This image is chopped into a series of tiles, each tile_height
pixels high and the width of in. The tiles are then rearranged into a grid
across tiles across and down tiles down in row-major order.
Supplying tile_height, across and down is not strictly necessary, we
only really need two of these. Requiring three is a double-check that the
image has the expected geometry.
