Pardon me if I am just being obtuse, but I could find no easy way to add an
image or artwork to a layout. I've tried pstoedit but that utility (in
addition to being broken if you are in a directory path that has a space in it)
only works for text.
Because I am under the gun, I had to gin up something to get a project out the
door. So I came up with a quick and dirty solution.
Step 1: Generate an ASCII PBM file - I use GIMP. A monochrome (black and
white) image will be represented by a file full of "0" and "1". Call it
something like "art.pbm".
Step 2: Run the ASCII PBM file "art.pbm" through the following awk script and
put the output into a file, call it "art.out".
Step 3: Create a module library with a single component, call it something like
"Logo". The library will be called "Logo.mod".
Step 4: Edit the module library "Logo.mod", look for the $EndMODULE line, and
copy the contents of "art.out" immediately before it. Save the file.
Step 5: Edit the module library and move things around, add the module name,
etc.
Step 6: In PCBnew, add the module from the library and place it where you want.
I hope this makes sense and helps someone other than me. And I hope that I
have not reinvented the wheel. I'm sorry that I use awk as a script language
of choice, I suppose I could clean it up as a Perl script if there is any
interest.
