How I Made an e-signature on ubuntu with Xsane
1. Make an enlarged signature on paper, about y=2 in x=4 in or maybe a bit less
2. Use Xsane to scan into ubuntu at 200 dpi -- keeps the files size down.
3. Crop scan area so you scan only the signature an a tinsy bit more around it.
4. Save as a jpeg with no compression.
5. On Windows using ImageMagick's convert utility in a console:
convert -resize 400x400 signature.jpeg sig.eps (this should work the same on Linux)
Note: My sig.eps filesize was about 164 K. My previous ones were 5 K, but didn't work
quite right. This increase in signature file size seems to expand a prescription
PDF file size from 7 K to only around 14 K or so on my machines, and is fast.
You can putz around with the 400x400 setting to get the size on your signature
to suite you. You can also scan a higher dpi for a more black, dense signature,
but file size qrows quickly -- this makes inserting the signature into a
template slower, and the final file size larger. I tried one at 600 dpi. Looked
nice, but final signature file size was 1353 K with a noticeable slowdown in creating
a prescription.
6. Import into synapse following instructions on the wiki article Create an EPS Signature.
