I'd like to post one more patch. In this patch, --only-visible is
working for photo-mode.
Here is a (1.5MB!) 300 dpi render prepared with the following snippet
of my ever-expanding pcb Makefile:
http://live.midwesttelecine.com/pcb-render.png
DPI=300
OVERSAMPLE=2
PCB=/home/markrages/src/pcb/src/pcb
PCBOPTS= -x png --photo-mode --dpi $(shell echo $$((
$(OVERSAMPLE)*$(DPI) ))) --use-alpha --only-visible
$(BOARD_NAME)-front.png: $(BOARD_NAME).pcb
$(PCB) $(PCBOPTS) $(BOARD_NAME).pcb
$(BOARD_NAME)-back.png: $(BOARD_NAME).pcb
$(PCB) $(PCBOPTS) --outfile $(BOARD_NAME)-back.png --photo-flip-x
--photo-flip-y $(BOARD_NAME).pcb
$(BOARD_NAME)-render.png: $(BOARD_NAME)-front.png $(BOARD_NAME)-back.png
montage $(BOARD_NAME)-front.png $(BOARD_NAME)-back.png -tile x1
-shadow -geometry "+50+50" -resize $(shell echo $$(( 100 /
$(OVERSAMPLE))))% -background lightblue $(BOARD_NAME)-render.png
