Project description
Kern determiner
Work out how far apart things should be (very quickly)
kerndeterminer
is a Rust-based library for determining a kern
value between two glyphs of a font source file.
(Don't use it for Latin kerning; it won't work. But it works fine for many other scripts)
Given a font, two glyphs, and a target distance (and a few other parameters),
kerndeterminer
will return the kern value which places the contours of the
two glyphs the given distance apart at their closest point. The graphic
below explains the main parameters and the effect of kerndeterminer
:
How to use
First, create a KernDeterminer
object. This loads the font, since you'll
probably be making quite a few calls to determine_kern
and won't want to
load the font each time:
from kerndeterminer import KernDeterminer
kerner = KernDeterminer("MyFont.glyphs")
The font source can be any source loadable by the Rust version of Babelfont (currently Glyphs version 3 files, UFO, and Designspace files).
Next, call the determine_kern
method on that object:
kern = kerner.determine_kern(
"JIMi10", # Left glyph
"REu1", # Right glyph
"Regular", # Master name
120, # Target distance
200, # Height
0.8, # Max tuck
)
This will return the optimal kerning value for that pair at the given parameters. Note:
- The
height
parameter is used to translate the left glyph vertically befor kerning. This is used in Arabic fonts with cursive attachment. - The
max_tuck
parameter is a ratio of the left glyph's width which forms an upper limit on the kerning value. For example, ifmax_tuck
is 0.5, the leftmost point on the right glyph can only be placed so that it is 50% of the way underneath the left glyph:
