Re: [Fxruby-users] Converting Image Formats

Lyle,

I don't think that will work, img is still a FXBMPImage. What you really =
want=20
to do is call (the ruby alternatives)

fxloadBMP(parameters);

and=20

fxsaveJPG(parameters);

You don't need the image class if you're not going to show it on screen.=20
