# Checking outlines after extrapolation
|
||
|
||
It was necessary to extrapolate a `Light` master to allow Fira Code to build via FontMake. As a result, some outline errors may have made their way into the glyphs in this new Master, because extrapolation is a useful but imperfect tool.
|
||
|
||
For the most part, I will abstain from fixing every little outline issue, because by and large, things here are well-drawn, and haven't been extrapolated in too extreme a manner.
|
||
|
||
## General Process
|
||
|
||
I will use the Glyphs App extension Red Arrows to find potential problems, then check them over and fix what seems to be clearly wrong.
|
||
|
||
If it is not super obvious how to fix a potential issue, I will generally:
|
||
- Check what the Bold master does
|
||
- Check what Fira Mono (the ancestor of Fira Code) does in its Regular master
|
||
- Copy the existing layer to the background, and make that copied layer visible to provide a basic guide for my changes. For example:
|
||
|
||
|
||
|
||
I am not trying to change the design, but rather, to fix unintended vector issues that make the design less useful.
|
||
|
||
### /U-cy
|
||
|
||
The main stem of this glyph has a "kink" that seems unintentional.
|
||
|
||
|
||
|
||
|
||
### Zhedescender-cy
|
||
|
||
This has a component that isn't needed, and this juts out in the Bold master, causing an outline blip.
|
||
|
||
|
||
|
||
|
||
|
||
|
||
|
||
If we look at Fira Sans, it's clear what this shape is supposed to do:
|
||
|
||
|
||
|
||
The component was transformed to (10%, 10%) – way too small. I've adjust that to (85%, 100%) in the Bold and (100%,100%) in the light. Now it's like this:
|
||
|
||
|
||
|
||
|
||
|
||
## Kastroke-cy
|
||
|
||
This crossbar is overly-thick, compared to others – I'll thin it out a bit:
|
||
|
||
|
||
|
||
|
||
## Kahook-cy
|
||
|
||
Before:
|
||
|
||
|
||
|
||
Now:
|
||
|
||
|
||
|
||
|
||
## Lha-cy
|
||
|
||
Mismatch in upper-left:
|
||
|
||
|
||
I removed the overlap in that stroke:
|
||
|
||
|
||
|
||
## be-cy
|
||
|
||
The ascender has an issue:
|
||
|
||
|
||
|
||
|
||
|
||
## ve-cy
|
||
|
||
Inflected curve:
|
||
|
||
|
||
|
||
|
||
|
||
## ze-cy
|
||
|
||
(Almost certainly) unintended curve upwards:
|
||
|
||
|
||
|
||
|
||
|
||
## ii-cy
|
||
|
||
Unintended upwards-handles.
|
||
|
||
|
||
|
||
The bold looks better:
|
||
|
||
|
||
|
||
So:
|
||
|
||
|
||
|
||
### komije-cy
|
||
|
||
Ouch:
|
||
|
||
|
||
|
||
Better:
|
||
|
||
|
||
|
||
|
||
### Chi
|
||
|
||
These feet aren't suppose to be angled so sharply:
|
||
|
||
|
||
In Fira Mono, you can see that the angle simply becomes less steep:
|
||
|
||
|
||
|
||
|
||
So:
|
||
|
||
|
||
|
||
### kaiSymbol
|
||
|
||
Not-quite-vertical strokes:
|
||
|
||
|
||
|
||
Straightened in Bold & Reg:
|
||
|
||
|
||
|
||
### betaSymbol
|
||
|
||
These lines are't supposed to intersect:
|
||
|
||
|
||
|
||
|
||
|
||
### Nine
|
||
|
||
|
||
|
||
|
||
|
||
(similar problem in /nine.tosf)
|
||
|
||
|
||
### asciitilde_greater.liga
|
||
|
||
Broken connection on right side:
|
||
|
||
|
||
|
||
|
||
|
||
### asciitilde_asciitilde_greater.liga
|
||
|
||
Broken connection on right side:
|
||
|
||
|
||
|
||
I've just scooted the curvy thing towards the arrow by a bit.
|
||
|
||
|
||
|
||
### uniE0A0
|
||
|
||
Broken connection:
|
||
|
||
|
||
|
||
Fixed:
|
||
|
||
|
||
|
||
### r.001
|
||
|
||
|
||
|
||
|
||
|
||
### ae
|
||
|
||
This curve isn't quite continuous:
|
||
|
||
|
||
|
||
I've made it a little more graceful:
|
||
|
||
|
||
|
||
|
||
|
||
### "Incorrect smooth connections" in several glyphs:
|
||
|
||
Like these slight kinks:
|
||
|
||
|
||
|
||
Should be this:
|
||
|
||
|
||
|
||
============================================================
|
||
|
||
## (Small) issues I'm leaving
|
||
|
||
Often, crossbars have unnecessary points. These aren't really needed for the shapes and add a very small amount of data, but they're harmless, so I won't remove them right now.
|
||
|
||
|
||
|
||
|
||
---
|
||
|
||
There are many instances of overlapping shapes that, while technically fine, might not render absolutely perfectly. I'll leave these, however, as they will probably bother no one.
|
||
|
||
|
||
|
||
---
|
||
|
||
Small inflections, or semi-vertical handles that clearly should be that way:
|
||
|
||
|
||
|
||
---
|
||
|
||
Some curvy shapes have slight issues around smooth connections. I'm looking at intermediate weights to make sure there aren't huge kinks (which is a concern in angled curve points), but otherwise mostly leaving these.
