gEDA-user: Suggestion for DJ

2007-09-26 Thread John Coppens
Hi...

I just played around with background images in PCB, which works fine. It
took some work, because of documentation problems.

DJ: I'd suggest adding a comment on you 'background image' page,
telling that it is possible to change the board size _after_ starting pcb
--bg-image xxx The image will then adapt to the new board size. 

Else, maybe some confusion might appear, as the ps/pdf docs with PCB say
it's possible to define the size on startup, but those commands are not
accepted (--size doesn't work). The help page that appears running pcb,
doesn't seem to provide an alternative to pre-define the board size.

In fact, it might even be simpler _not_ to scale/crop the original image,
but just measure two known points (corners) and then change pcb's size
setting to make the image scale right.

Cheers,
John

The idea was that you'd crop the image to be exactly just the board.
Then you set the new pcb's size to what you know the board is, and
everything lines up.  Otherwise, getting the size/math right is
trickier.

I'll add the other note.
