Constant libjxl_sys::JXL_DEC_DC_IMAGE

pub const JXL_DEC_DC_IMAGE: JxlDecoderStatus = 2048;

Informative event by JxlDecoderProcessInput: DC image, 8x8 sub-sampled frame, decoded. It is not guaranteed that the decoder will always return DC separately, but when it does it will do so before outputting the full frame. JxlDecoderSetDCOutBuffer must be used after getting the basic image information to be able to get the DC pixels, if not this return status only indicates we’re past this point in the codestream. This event occurs max once per frame and always later than JXL_DEC_FRAME_HEADER and other header events and earlier than full resolution pixel data.
