		const AVPixFmtDescriptor *	desc,
		int	x,
		int	y,
		int	c,
		int	w,
		int	read_pal_component
	)

Read a line from an image, and write the values of the pixel format component c to dst.

Parameters

data	the array containing the pointers to the planes of the image
linesize	the array containing the linesizes of the image
desc	the pixel format descriptor for the image
x	the horizontal coordinate of the first pixel to read
y	the vertical coordinate of the first pixel to read
w	the width of the line to read, that is the number of values to write to dst
read_pal_component	if not zero and the format is a paletted format writes the values corresponding to the palette component c in data[1] to dst, rather than the palette indexes in data[0]. The behavior is undefined if the format is not paletted.

int av_get_pix_fmt_loss	(	enum AVPixelFormat	dst_pix_fmt,
		enum AVPixelFormat	src_pix_fmt,
		int	has_alpha
	)

Compute what kind of losses will occur when converting from one specific pixel format to another.

When converting from one pixel format to another, information loss may occur. For example, when converting from RGB24 to GRAY, the color information will be lost. Similarly, other losses occur when converting from some formats to other formats. These losses can involve loss of chroma, but also loss of resolution, loss of color depth, loss due to the color space conversion, loss of the alpha bits or loss due to color quantization. av_get_fix_fmt_loss() informs you about the various types of losses which will occur when converting from one pixel format to another.

Parameters

[in]	dst_pix_fmt	destination pixel format
[in]	src_pix_fmt	source pixel format
[in]	has_alpha	Whether the source pixel format alpha channel is used.

Returns: Combination of flags informing you what kind of losses will occur (maximum loss for an invalid dst_pix_fmt).
