PNG to Sprite transperancy problems

With people wanting me to create a theme version of my Concept Art , I started to learn how to create a theme but when I import images that has transparent backgrounds into RPCemu with Spr2Png but I get this black border around the sprites which is visable when the theme is applied.
How do I get a transparent background with sprites. when Im converting would be easier but doing it after conversion via paint would also work.
Thanks in advance.

Hi Matthew,

Just want to wish you success with your new theme and to let you know that I for one am really looking forward to seeing it. Ill fire up my RISC PC later today and see if I can help you with PNG to Sprite conversion, but im sure someone with more knowledge on the subject will be along shortly with an answer.

All the best,
Lee

Have a read of this thread. It might help

For my own pleasure I work on a DreamLinux inspired Iconset. The most Icons I need are ready. I use !Paint to reset the transparent areas.

Raik, are you planning on releasing your iconset?

I have changed any things so it works with the Pandora Angstrom.
Now I fiddle around if have a little bit time.
If anybody have a interest, maybe.

I’d be interested. There’s no decent alternative iconsets available for RISC OS AFAIK. They all look dated.

Thats what I’ve been doing for a couple of hours Lee, Converted files to sprite, add mask, selecting “none” in colour and filling over the blackness around the icons. This iconset/theme is now complete. It’s not the one based of my upcoming concept but its something else… I’ll post more details on it later.

Can’t wait to see it Martin :-)
