mlib_ImageTestFlags - test flags
cc [ flag... ] file... –lmlib [ library... ] #include <mlib.h> int mlib_ImageTestFlags(const mlib_image *img, mlib_s32 flags);
The mlib_ImageTestFlags() function tests the flags for a combination of the following predefined characteristics. Note that the result of zero means the conditions are satisfied.
MLIB_IMAGE_ALIGNED64 /* data address is 64-byte aligned */ MLIB_IMAGE_ALIGNED8 /* data address is 8-byte aligned */ MLIB_IMAGE_ALIGNED4 /* data address is 4-byte aligned */ MLIB_IMAGE_ALIGNED2 /* data address is 2-byte aligned */ MLIB_IMAGE_WIDTH8X /* width is multiple of 8 */ MLIB_IMAGE_WIDTH4X /* width is multiple of 4 */ MLIB_IMAGE_WIDTH2X /* width is multiple of 2 */ MLIB_IMAGE_HEIGHT8X /* height is multiple of 8 */ MLIB_IMAGE_HEIGHT4X /* height is multiple of 4 */ MLIB_IMAGE_HEIGHT2X /* height is multiple of 2 */ MLIB_IMAGE_STRIDE8X /* stride is multiple of 8 */ MLIB_IMAGE_ONEVECTOR /* stride is equal to width in bytes */ MLIB_IMAGE_USERALLOCATED /* data space has been allocated by user */ MLIB_IMAGE_ATTRIBUTESET /* image attribute flags have been set */
The function takes the following arguments:
Pointer to a mediaLib image structure.
Combination of a set of characteristics to be tested. It is formed by logically Oring one or more individual predefined characteristics.
The function returns an integer value containing results of test. Condition = 0 if satisfied; otherwise, Condition != 0.
