NAME
im_initdesc - initialises an image descriptor to specific values
SYNOPSIS
#include <vips/vips.h>
void im_initdesc( IMAGE *image,
int xsize, int ysize,
int bands, int bandbits, int bandfmt,
int coding, int type,
float xres, float yres,
float xo, float yo )
DESCRIPTION
im_initdesc(3) initialises the image descriptor according to the
entered values. More specifically the Xsize, Ysize, Bands, BandFmt,
Coding, Type, Xres, Yres, Xoffset and Yoffset members of the descriptor
are initialised by the correspondingly entered arguments. The members
fd, baseaddr, data and filename are not handled by this function. The
order of the args is the same as in vips/vips.h.
The bandbits parameter is deprecated and ignored by this function: you
can always pass zero.
Example: make a 512 by 512 one-band memory buffer.
if( !(im = im_open( "temp", "t" )) )
/* Error ...
im_initdesc( im,
512, 512,
1, 0, FMTUCHAR,
NOCODING, B_W,
1.0, 1.0,
0, 0 );
if( im_setupout( im ) )
/* Error ...
ALSO
im_open(3), im_setupout(3).
