icetImageNull(3) IceT Reference icetImageNull(3)
NAME
icetImageNull -- retrieve a placeholder for an empty image.
Synopsis
#include <IceT.h>
IceTImage icetImageNull( void );
Description
Images are created internally by the IceT library. Sometimes it is convenient to have a placeholder for a .igimage!null``null'' image, an
image that does not and cannot hold data. Null images require no allocated memory to function.
If your code has the potential of using an IceTImage image object that might not otherwise be initialized, use icetImageNull to set it to a
null object. This will ensure that IceT image functions that operate on it will behave deterministically.
A null image simply looks like an image with no pixels and has no color buffers. icetImageGetWidth, icetImageGetHeight, and icetImageGet-
NumPixels all return 0 for a null image. icetSetColorFormatand icetSetDepthFormatreturn ICET_IMAGE_COLOR_NONE and ICET_IMAGE_DEPTH_NONE,
respectively.
You can identify a null image with the icetImageIsNull function.
Return Value
A null image object.
Errors
None.
Warnings
None.
Bugs
None known.
