How does Scanahand calculate side bearings?
Posted: Mon Jun 10, 2013 2:10 pm
I am wondering how Scanahand calculates side bearings.
I am trying to produce a font using Scanahand 4.
For this particular font, no scanning is involved.
I am producing the artwork using Microsoft Paint using png files of the Basic and Extended Characters template.
From time to time I am adding a few glyphs to the artwork and then I am producing a new version of the font.
Thus far I have added 26 lowercase letters, some capitals and a few accented letters.
I have also added a vertical line from descender to ascender in the cell for the vertical bar character so as to fix the overall height of the characters.
Here is some transcript from my notes.

Try a capital E by adapting a copy of H.
Try an F by adapting a copy of E.
Try an L by adapting a copy of E.
Try a T by adapting a copy of E.
Try an I by adapting a copy of T.
Try making the font MyTest_013.ttf using Scanahand 4.0 (build 151).
Regular
Auto
Smooth

I studied the font in FontCreator 7.0.
I note that in the MyTest_013.ttf font, when studied in FontCreator 7.0, that some of the capitals have negative values of one or both of the side bearings. This seems strange.
Is this what is to be expected?
I am wondering whether this is an effect of not having a complete of capitals artwork.
So I am wondering how Scanahand calculates side bearings please.
