As explained privately it is not tecnically possible. First of all becouse while RLE8 compression can be used in every 256-color images, RLE5 and LZ5 compression are instead limited. They can be used only if image use a 5-bit palette (max 32 colors).

So... the automate approach let the program to use the best compression possible, seeing witch one can be actually be used.
Moreover... I am not able to make a RLE5 compression routine.... and I think it is useless becouse LZ5 is much more efficient.

Finally... source code structure is abstract so it would be very hard to add this feature.

However thank for your suggestion. Nobun.
