mlib_ImageCreate(3MLIB) mediaLib Library Functions mlib_ImageCreate(3MLIB) NAME
mlib_ImageCreate - image creation SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_image *mlib_ImageCreate(mlib_type type, mlib_s32 channels, mlib_s32 width, mlib_s32 height); DESCRIPTION
The mlib_ImageCreate() function creates a mediaLib image data structure and allocates memory space for image data. The data type of the image can be MLIB_BIT, MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, MLIB_INT, MLIB_FLOAT, or MLIB_DOUBLE. To obtain the best performance, it is recommended that you use this function to create a mediaLib image whenever possible, as this guaran- tees alignment. PARAMETERS
The function takes the following arguments: type Image data type. channels Number of channels in the image. width Width of image in pixels. height Height of image in pixels. RETURN VALUES
The function returns a pointer to the mlib_image data structure. ATTRIBUTES

mlib_ImageSetStruct - set image data structure SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageSetStruct(mlib_image *image, mlib_type type, mlib_s32 channels, mlib_s32 width, mlib_s32 height, mlib_s32 stride, const void *datbuf); The mlib_ImageSetStruct() function sets a mediaLib image data structure using parameters supplied by the user. The mlib_ImageSetStruct() 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) o datbuf should not be NULL Whenever MLIB_FAILURE is returned, the original image data structure is not changed. If the data buffer in the image data structure is not NULL, it is the user's responsibility to free it if necessary. 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 set successfully. MLIB_FAILURE is returned when the image data structure can not be set according to the parameters supplied.
