IFF HAM6 Bug [XnView 1.94]
Posted: Mon Nov 24, 2008 2:45 pm
Hi, I 'm new there and I found a small bug:
In HAM6 mode there are some pictures that are displayed correctly on real Amiga 500, but in XnView sometime there are bad colours on left side of picture. This is probably caused by wrong interpretation of Amiga IFF HAM6 specifications becase each new line should start with Palette index 0 by default. I think, XnView takes the value of the last pixel from previous line. So if the line starts with a modification and the RGB value differs much from the pixels on opposite side, it results in lines of bad colours.
