|
|

|

|
|
|
|

|
|
int xsize, int ysize,
|
|

|
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

|
.B bandbits
|
|
parameter is deprecated and ignored by this function: you can always pass zero.
|
|
|
|
Example: make a 512 by 512 one-band memory buffer.
