int im_mask2vips( DOUBLEMASK *in, IMAGE *out )


im_vips2mask(3) returns a DOUBLEMASK of name out_name containing the data from IMAGE in. Images must have either one band, a width of 1, or a height of 1. Returns NULL on error, and a new mask on success. The scale field is set to 1.0 and the offset to 0.0.

im_mask2vips(3) writes the doubles held in mask in to the IMAGE out. It creates a one-band image of the same size as in. It returns 0 on success and -1 on error. The scale and offset fields are ignored.
