This is a plugin for the Glyphs font editor by Georg Seifert. It calculates all active instances for the given glyph and draws them behind your paths. By default, it draws all active instances on top of each other using a transparent fuchsia/lavender color:
After installation, it will add the menu item View > Show Interpolations (de: Interpolationen zeigen, fr: Montrer Interpolations, es: Mostrar Interpolaciones, zh: 💗插值). You can set a keyboard shortcut in System Preferences.
Please install the plugin via the built-in Plugin Manager, available via Window > Plugin Manager. If this is not possible for some reason or another, follow these steps:
- Download the complete ZIP file and unpack it, or clone the repository.
- Double click the
.glyphsReporterfile. Confirm the dialog that appears in Glyphs. - Restart Glyphs
- Open a glyph in Edit View.
- Use View > Show Interpolations to toggle the preview of the instances.
To center the interpolations under the frontmost layer, Ctrl- or right-click anywhere in the canvas to invoke the context menu, and choose Center Interpolations (de: Interpolationen zentrieren, fr: Centrer interpolations, es: Centrar interpolaciones, zh: 以中心对齐).
Alternatively, you can also align at a certain node. To do that, select a node, bring up the context menu, and choose Align Interpolations at Selected Node (de: Interpolationen an ausgewähltem Punkt ausrichten, es: Alinear las interpolaciones a nodo seleccionado, fr: Aligner les interpolations au point selectionné, zh: 以所选点为基点对齐). The node in question will then be marked with a star. To cancel point alignment, select the starred node, and choose Do not Align Interpolations at Selected Node (de: Interpolationen nicht an ausgewähltem Punkt ausrichten, es: No alinear las interpolaciones a nodo seleccionado, fr: Ne pas aligner les interpolations au point selectionné, zh: 不以所选点为基点对齐) from the context menu.
To only view specific interpolations, add this custom parameter to the instance(s) you want to preview in File > Font Info > Exports:
Property: ShowStyles
Value: -
Value: .1;.8;.2
Value: 1;0.5;0;0.1
The Value defines the color of the instance. You can either leave the value blank to use the default color. Or, you can set semicolon-separated RGB values between 0 and 1. If you supply a fourth value, it will be interpreted as alpha (opacity: 1.0 = opaque, 0.0 = invisible).
If you want to change the color globally, add the parameter in File > Font Info > Font > Custom Parameters.
Legacy note: In Glyphs 2, the parameter is called ShowInterpolation.
If you want the plug-in to also display inactive instances, run this in Macro Window:
Glyphs.defaults["com.mekkablue.ShowInterpolation.showDisabledInstances"]=True
The plugin needs Glyphs 2.4 or higher, running on OS X 10.9.5 or later.
