mlib_ImageCreateSubimage - subimage creation SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_image *mlib_ImageCreateSubimage(mlib_image *img, mlib_s32 x, mlib_s32 y, mlib_s32 w, mlib_s32 h); DESCRIPTION
The mlib_ImageCreateSubimage() function creates a mediaLib image data structure for a subimage based on a source image. Note that the mem- ory space of the source image data is used for the subimage data. The data type of the image can be MLIB_BIT, MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, MLIB_INT, MLIB_FLOAT, or MLIB_DOUBLE. PARAMETERS
The function takes the following arguments: img Pointer to source image. x X coordinate of subimage origin in the source. y Y coordinate of subimage origin in the source. w Width of the subimage in pixels. h Height of the subimage in pixels. RETURN VALUES
The function returns a pointer to the mlib_image data structure. ATTRIBUTES

mlib_ImageSetStruct(3MLIB) mediaLib Library Functions mlib_ImageSetStruct(3MLIB) NAME
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); DESCRIPTION
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. PARAMETERS
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. RETURN VALUES
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. ATTRIBUTES
