It performs color conversion together with 2X zooming. The luminance component is stored in Y, the chrominance components are stored in U and V, respectively. The size of the chrominance image depends on the chroma format used by the sequence. In this sequence, the chrominance components are subsampled 2-to-1 in both the horizon- tal and vertical directions in respect to the luminance component.PARAMETERSThe function takes the following arguments: abgr Pointer to the destination packed ABGR image. abgr must be 8-byte aligned. y Pointer to the source Y component. y must be 8-byte aligned. u Pointer to the source U component. u must be 4-byte aligned. v Pointer to the source V component. v must be 4-byte aligned. width Width of the image. width must be a multiple of 8. height Height of the image. height must be a multiple of 2. abgr_stride Stride, in bytes, between adjacent rows in the ABGR image. abgr_stride must be a multiple of 8. y_stride Stride, in bytes, between adjacent rows in the Y component image. y_stride must be a multiple of 8. uv_stride Stride, in bytes, between adjacent rows in the U and V component images. uv_stride must be a multiple of 8.RETURN VALUESThe function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.ATTRIBUTESSee attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Committed | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe | +-----------------------------+-----------------------------+SEE ALSOmlib_VideoColorYUV2ABGR420_W(3MLIB), mlib_VideoColorYUV2ABGR420_WX2(3MLIB), mlib_VideoColorYUV2ABGR420_WX3(3MLIB), mlib_VideoCol- orYUV2ABGR420_X3(3MLIB), attributes(5) SunOS 5.11 2 Mar 2007 mlib_VideoColorYUV2ABGR420_X2(3MLIB)
