| |
| void im_initdesc( IMAGE *image, |

| int coding, int type, |
| float xres, float yres, |
| float xo, float yo ) |
| .SH DESCRIPTION |
| .B 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 |

| Example: make a 512 by 512 one-band memory buffer. |
