No. Images are converted to bitmaps, and included in the PDF format in 
the document.  It is rather easy to specify a transparent color in PDF 
images, but Ipe doesn't know about this yet.

Ipe always includes the original image in the PDF output.  Only for 
display on the screen is the image down-sampled (for reasons of speed).
