Function av_image_fill_color

pub unsafe extern "C" fn av_image_fill_color(
    dst_data: *const *mut u8,
    dst_linesize: *const isize,
    pix_fmt: i32,
    color: *const u32,
    width: i32,
    height: i32,
    flags: i32,
) -> i32

Overwrite the image data with a color. This is suitable for filling a sub-rectangle of an image, meaning the padding between the right most pixel and the left most pixel on the next line will not be overwritten. For some formats, the image size might be rounded up due to inherent alignment.

If the pixel format has alpha, it is also replaced. Color component values are interpreted as native integers (or intfloats) regardless of actual pixel format endianness.

This can return an error if the pixel format is not supported. Normally, all non-hwaccel pixel formats should be supported.

Passing NULL for dst_data is allowed. Then the function returns whether the operation would have succeeded. (It can return an error if the pix_fmt is not supported.)

@param dst_data data pointers to destination image @param dst_linesize linesizes for the destination image @param pix_fmt the pixel format of the image @param color the color components to be used for the fill @param width the width of the image in pixels @param height the height of the image in pixels @param flags currently unused @return 0 if the image data was filled, a negative AVERROR code otherwise
