raoulduke_esq posted an AWK script a while back which works with ASCII
PBMs. I run this using cygwin and I've found it works well enough. I
don't have time to search for it in the group posts, so here it is:
# This script will take an ASCII PBM B&W file and convert it to a series
# of "DS" (Draw Segment) statements in PCBNEW syntax. The deltaX and deltaY
# is defined in "step" which is in uints of 1/10 mil. The layer is
currently
# set to 21, the component layer silkscreen. Swap bg & fg based on whether
# black or white is the foreground.
#
# State 0 : look for magic number - must be P1 (can be P4 for raw file)
# State 1 : look for height & width
# State 2 : process data
# State 3 : done with data - skip the rest
#
BEGIN { state = 0; step = 40; layer = 21; fg = "1"; bg = "0"; }
{if (NR == 1) {
state = 1;
if ($1 != "P1") {
printf("Must supply an ASCII PBM image file\n");
exit 1
}
next;
}
}
/^#/ { next } # Comment line, skip it
{if (state == 1) {
width = $1;
height = $2;
buff = "";
state = 2;
Y = - ((step * height) / 2);
initX = - ((step * width) / 2);
next;
}
}
{if (state == 2) {
buff = buff $1;
if (length( buff ) >= width) {
scanline = substr( buff, 1, width );
buff = substr( buff, width + 1 );
Y += step;
X = initX;
while ( Z1 = index( scanline, fg )) {
scanline = substr( scanline, Z1 );
Z2 = index( scanline, bg );
if (Z2 == 0)
Z2 = length( scanline ) + 1;
scanline = substr( scanline, Z2 );
Z1 = step * Z1 + X;
Z2 = step * Z2 + Z1 - 2 * step;
X = Z2;
printf( "DS %d %d %d %d %d %d\n", Z1, Y, Z2, Y, step,
layer );
}
height--;
if (height == 0)
state = 3;
}
}
}
{if (state == 3) { nextfile; }}
Instructions:
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":
awk -f ConvertPBM.awk pic.pbm > 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.
Regards,
Robert.
