icetImageGetNumPixels(3) IceT Reference icetImageGetNumPixels(3) NAME
icetImageGetWidth,icetImageGetHeight,icetImageGetNumPixels-- get dimensions of an image Synopsis #include <IceT.h> IceTSizeType icetImageGetWidth ( const IceTImage image ); IceTSizeType icetImageGetHeight ( const IceTImage image ); IceTSizeType icetImageGetNumPixels ( const IceTImage image ); Description icetImageGetWidth,icetImageGetHeight,and icetImageGetNumPixelsallow you to query the size of an image with respect to the number of pixels. These functions define the buffer size returned by icetImageGetColor and icetImageGetDepth. Return Value icetImageGetWidthreturns the number of pixels along the horizontal axis of the image and icetImageGetHeightreturns the number of pixels along the vertical axis of the image. icetImageGetNumPixelsis a convenience function that returns the total number of pixels in image (the width times the height). Errors None. Warnings None. Bugs None known.

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.
