FontForge: Scale lowercase glyphs vertically
|
|
─────────────────────────────────────────────

|
|
matching the Transform dialog with all options checked:
|
|
|
|
- Transform All Layers
|
|
- Transform Guide Layer Too
|
|
- Transform Width Too
|
|
- Transform kerning classes too
|
|
- Transform simple positioning features & kern pairs
|
|
- Round To Int
|
|
|
|
Run inside FontForge (or via build.py which sets `f` before running this).
