Good question (and the answer is yes). Load the BMP image from a file 
using code like this:

     img = FXBMPImage.new(getApp(), nil,
         IMAGE_KEEP|IMAGE_SHMI|IMAGE_SHMP)
     FXFileStream.open("image.bmp", FXStreamLoad) do |stream|
         img.loadPixels(stream)
     end

and then save it as a JPEG using code like this:

     FXFileStream.open("image.jpg", FXStreamSave) do |stream|
         img.savePixels(stream)
     end

Hope this helps,
