Sure it's possible but I'm not sure if it's worth wasting time and energy on this. Why not use GIF?

Otherwise is it possible to add at the function getattribute() => get palette of brush ?

Actually is not possible to get palette picture 8bit with Hollywood. Is very important for my project

Actually, there is a little undocumented function called GetPen(). This can be used to get a palette entry but it will only work with IFF ILBM images. It is needed by Malibu, that's why it is there. And since it only works with IFF ILBM it is undocumented. You have to pass the desired palette index to GetPen(), e.g.

Code: Select all

rgb = GetPen(0)   ; return color of palette entry 0

That's not possible because Hollywood doesn't store images as chunky pixels. But if you carefully read the to do section you'll see that palette support has been on the agenda for quite some time now :)
