i simply embedd larger jpg images using the "external-image", but all my images scale wrong. It neiter works with the awt-viewer, nor in pdf.
What does "scale wrong" mean? It seems FOP puts images 1:1 into the PDF unless constraints force it to scale it down, which means they are rendered with 1/72 inch per pixel. This means a 100x100 pixel image is roughly 35.3mm x 35.3mm. Is this what you expect?
