https://gitlab.com/freepascal.org/fpc/source/-/blob/main/packages/pasjpeg/src/jdcolor.pas#L293 Bug: This line (293) is wrong:\ `outptr := JSAMPLE_PTR(@output_buf^[0]);`\ Now we have (outptr^ = rowpointer),\ but we want (outptr = rowpointer). Solution: Remove the @-operator, so we get:\ `outptr := JSAMPLE_PTR(output_buf^[0]);`
