im_smudge(3) im_smudge(3)
NAME
im_smudge, im_smear - filter and smudge in place
SYNOPSIS
#include <vips/vips.h>
int
im_smudge( im, ix, iy, r )
IMAGE *im;
int ix, iy;
Rect *r;
int
im_smear( im, ix, iy, r )
IMAGE *im;
int ix, iy;
Rect *r;
DESCRIPTION
im_smudge() performs a low-pass filter of the pels inside rect r. Rect
r is clipped against the edges of the image. im_smear() is not very
useful.
Both these functions are `in place,' that is, they write directly to
the output image! Be very careful, you can destroy data.
RETURN VALUE
All functions return 0 on success and -1 on error.
