NAME

im_invalidate - flush caches related to an image  

SYNOPSIS

#include <vips/vips.h>

void im_invalidate( IMAGE *im )

 

DESCRIPTION

im_invalidate(3) marks all caches related to the image as invalid and requring recalculation. It needs to be called if an image changes after being made: for example, after a paint action, or perhaps after a new frame has arrived from a video source.

Any invalidate callbacks registered on any of the affected images are triggered.
