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.


SEE ALSO

       im_insertplace(3), im_readpoint(3).
