Newbie - check formatting

[DaveH]

New to GnuCash and really liking it. I am trying to format my checks for
printing. Downloaded the last couple of months of these message archives and
have not seen these questions addressed so asking them here...

I am reading these docs:
https://www.gnucash.org/docs/v2.6/C/gnucash-guide/check_format_info.html

Running Windows 7


I want to use an image of my signature to pre-sign my checks. I see the
PICTURE check item type - is there a specific file format needed?

Can I use more than one PICTURE image (sig file and logo)

What is the unit of measurement used for the coordinates (depends on
printer? Points (as in 72/inch) or other)

Is there a way to draw a line outside of using a one-bit tall image of the
right length.

Finally, is there a download site for pre-designed nnnn.chk files?


Many thanks - really happy with GnuCash so far. A lot snappier performance
than QB and just does what I am looking for - no creeping featuritis...
