ConvertBufferRowsToDPX0()

CODEC_ERROR ConvertBufferRowsToDPX0	(	PIXEL *	input_buffer,
		size_t	input_pitch,
		PIXEL *	output_buffer,
		size_t	output_pitch,
		DIMENSION	width,
		DIMENSION	height
	)

Convert the intermediate decoded image into the output image in DPX pixel format.

This routine converts the decoded result of a sample that was YUV 4:2:2 encoded into the DPX pixel format of 10-bit RGB packed into a 32-bit word with two zero bits for padding.

Here is the caller graph for this function:

DPX_SetByteSwapFlag()

CODEC_ERROR DPX_SetByteSwapFlag

)

Prepare to write a DPX file.

This routine should be called before using any routines that pack images into the pixel format used for DPX files so that the byte swapping flag is set.

Pack10()

uint32_t Pack10	(	uint32_t	R,
		uint32_t	G,
		uint32_t	B
	)

Pack the color components into a 32-bit word.

The common pixel format used for DPX files packs the three color primaries as 10 bits per component in a 32-bit word with two unused zero bits.

The input values have 16 bits of precision since that is the bit depth used by decoder as its internal pixel format. The packed word is byte swapped.

Here is the caller graph for this function:

PackBayerRowsToDPX0()

CODEC_ERROR PackBayerRowsToDPX0	(	PIXEL *	input_buffer,
		size_t	input_pitch,
		PIXEL *	output_buffer,
		size_t	output_pitch,
		DIMENSION	width,
		DIMENSION	height
	)

Pack the intermediate decoded image into the output image in DPX pixel format.

The only DPX pixel format supported is the most common pixel format of 10-bit RGB packed into a 32-bit word with two zero bits for padding.

Here is the caller graph for this function:

PackBufferRowsToDPX0()

CODEC_ERROR PackBufferRowsToDPX0	(	PIXEL *	input_buffer,
		size_t	input_pitch,
		PIXEL *	output_buffer,
		size_t	output_pitch,
		DIMENSION	width,
		DIMENSION	height
	)

Pack the intermediate decoded image into the output image in DPX pixel format.

The only DPX pixel format supported is the most common pixel format of 10-bit RGB packed into a 32-bit word with two zero bits for padding.
