mlib_imageresetstruct

mlib_ImageResetStruct(3MLIB)											      mlib_ImageResetStruct(3MLIB)

NAME

       mlib_ImageResetStruct - reset image data structure

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status  mlib_ImageResetStruct(mlib_image  *image, mlib_type type, mlib_s32 channels, mlib_s32 width, mlib_s32 height, mlib_s32 stride,
       const void *datbuf);

       The mlib_ImageResetStruct() function resets a mediaLib image data structure using parameters supplied by the user.

       The mlib_ImageResetStruct() function returns MLIB_FAILURE if the supplied parameters do not pass the following sanity checks:

	 o  image should not be NULL

	 o  type should be MLIB_BIT, MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, MLIB_INT, MLIB_FLOAT, or MLIB_DOUBLE

	 o  channels should be between 1 and 4

	 o  width should be greater than 0

	 o  height should be greater than 0

	 o  stride should be no less than width * channels * (size of type in bytes)

       Whenever MLIB_FAILURE is returned, the original image data structure is not changed.

       When datbuf is NULL, the original data buffer is reused.  If mlib_ImageIsUserAllocated(image)==0, such as the case the image data structure
       was  created  by mlib_ImageCreate(), and the data buffer size required by the parameters supplied is larger than the original, MLIB_FAILURE
       is returned.

       When datbuf is not NULL, if mlib_ImageIsUserAllocated(image)==0, the original data buffer is freed, otherwise the original data	buffer	is
       not freed.  If datbuf points to the original data buffer, it is not freed.

       The function takes the following arguments:

       image	       Pointer to the image data structure.

       type	       Image data type.  It can be MLIB_BIT, MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, MLIB_INT, MLIB_FLOAT, or MLIB_DOUBLE.

       channels        Number of channels in the image.

       width	       Width of image in pixels.

       height	       Height of image in pixels.

       stride	       Stride of each row of the data space in bytes.

       datbuf	       Pointer to the image data buffer.

       MLIB_SUCCESS  is returned if the image data structure is reset successfully. MLIB_FAILURE is returned when the image data structure can not
       be reset according to the parameters supplied.
