hasChanged()

Return a bool indicating if a font contains changes.

hasInterface()

newGlyph(name, clear=None)

Make a new glyph with name in the layer. :

>>> glyph = layer.newGlyph("A")

The newly created BaseGlyph will be returned.

If the glyph exists in the layer and clear is set to False, the existing glyph will be returned, otherwise the default behavior is to clear the exisiting glyph.

openInterface()

Open the interface for the object

removeOverlap(round=1)

Remove overlap for all glyphs in the font. Optionally a round value can be provided.

renameGlyph(oldName, newName, renameComponents=True, renameGroups=True, renameKerning=True, renameGlyphOrder=True)

Rename a glyph. optionally you can rename this glyph in components, groups, kerning and glyphOrder.

font = CurrentFont()
font.renameGlyph(oldName, newName, renameComponents=True, renameGroups=True, renameKerning=True, renameGlyphOrder=True)

save(path=None, showProgress=False, formatVersion=None, removeUnreferencedImages=None)

Save the font to path.

>>> font.save()
>>> font.save("/path/to/my/font-2.ufo")

If path is None, use the font’s original location. The file type must be inferred from the file extension of the given path. If no file extension is given, the environment may fall back to the format of its choice. showProgress indicates if a progress indicator should be displayed during the operation. Environments may or may not implement this behavior. formatVersion indicates the format version that should be used for writing the given file type. For example, if 2 is given for formatVersion and the file type being written if UFO, the file is to be written in UFO 2 format. This value is not limited to UFO format versions. If no format version is given, the original format version of the file should be preserved. If there is no original format version it is implied that the format version is the latest version for the file type as supported by the environment.

.. note:

Environments may define their own rules governing when a file should be saved into its original location and when it should not. For example, a font opened from a compiled OpenType font may not be written back into the original OpenType font.

naked()

appendGuideline(position=None, angle=None, name=None, color=None, guideline=None)

Append a new guideline to the font.

>>> guideline = font.appendGuideline((50, 0), 90)
>>> guideline = font.appendGuideline((0, 540), 0, name="overshoot",
>>> color=(0, 0, 0, 0.2))

position must be a coordinate indicating the position of the guideline. angle indicates the angle of the guideline. name indicates the name for the guideline. This must be a string or None. color indicates the color for the guideline. This must be a color or None. This will return the newly created BaseGuidline object.

guideline may be a BaseGuideline object from which attribute values will be copied. If position, angle, name or color are specified as arguments, those values will be used instead of the values in the given guideline object.

autoUnicodes()

Use heuristics to set Unicode values in all glyphs.

>>> font.autoUnicodes()

Environments will define their own heuristics for automatically determining values.

This applies only to the default layer.

clearGuidelines()

Clear all guidelines.

>>> font.clearGuidelines()

close(save=False)

Close the font.

>>> font.close()

save is a boolean indicating if the font should be saved prior to closing. If save is True, the BaseFont.save method will be called. The default is False.

copyData(source)

Copy data from source into this font. Refer to BaseFont.copy for a list of values that will be copied.

duplicateLayer(layerName, newLayerName)

Duplicate the layer with layerName, assign newLayerName to the new layer and insert the new layer into the font. :

>>> layer = font.duplicateLayer("layer 1", "layer 2")

generate(format, path=None, **environmentOptions)

Generate the font to another format.

>>> font.generate("otfcff")
>>> font.generate("otfcff", "/path/to/my/font.otf")

format defines the file format to output. Standard format identifiers can be found in BaseFont.generateFormatToExtension:

Environments are not required to support all of these and environments may define their own format types. path defines the location where the new file should be created. If a file already exists at that location, it will be overwritten by the new file. If path defines a directory, the file will be output as the current file name, with the appropriate suffix for the format, into the given directory. If no path is given, the file will be output into the same directory as the source font with the file named with the current file name, with the appropriate suffix for the format.

Environments may allow unique keyword arguments in this method. For example, if a tool allows decomposing components during a generate routine it may allow this:

>>> font.generate("otfcff", "/p/f.otf", decompose=True)

getCharacterMapping()

Get a reversed map of component references in the font. { ‘A’ : [‘Aacute’, ‘Aring’] ‘acute’ : [‘Aacute’] ‘ring’ : [‘Aring’] etc. }

getLayer(name)

Get the BaseLayer with name.

>>> layer = font.getLayer("My Layer 2")

getReverseComponentMapping()

Create a dictionary of unicode -> [glyphname, …] mappings. All glyphs are loaded. Note that one glyph can have multiple unicode values, and a unicode value can have multiple glyphs pointing to it.

insertLayer(layer, name=None)

Insert layer into the font. :

>>> layer = font.insertLayer(otherLayer, name="layer 2")

This will not insert the layer directly. Rather, a new layer will be created and the data from layer will be copied to to the new layer. name indicates the name that should be assigned to the layer after insertion. If name is not given, the layer’s original name must be used. If the layer does not have a name, an error must be raised. The data that will be inserted from layer is the same data as documented in BaseLayer.copy.

interpolate(factor, minFont, maxFont, round=True, suppressError=True)

Interpolate all possible data in the font.

>>> font.interpolate(0.5, otherFont1, otherFont2)
>>> font.interpolate((0.5, 2.0), otherFont1, otherFont2, round=False)

The interpolation occurs on a 0 to 1.0 range where minFont is located at 0 and maxFont is located at 1.0. factor is the interpolation value. It may be less than 0 and greater than 1.0. It may be a integer/float or a tuple of two integer/float. If it is a tuple, the first number indicates the x factor and the second number indicates the y factor. round indicates if the result should be rounded to integers. suppressError indicates if incompatible data should be ignored or if an error should be raised when such incompatibilities are found.

isCompatible(other)

Evaluate interpolation compatibility with other.

>>> compatible, report = self.isCompatible(otherFont)
>>> compatible
False
>>> report
[Fatal] Glyph: "test1" + "test2"
[Fatal] Glyph: "test1" contains 1 contours | "test2" contains 2 contours

This will return a bool indicating if the font is compatible for interpolation with other and a string of compatibility notes.

newLayer(name, color=None)

Make a new layer with name and color. name must be a string and color must be a color or None.

>>> layer = font.newLayer("My Layer 3")

The will return the newly created BaseLayer.

removeGuideline(guideline)

Remove guideline from the font.

>>> font.removeGuideline(guideline)
>>> font.removeGuideline(2)

guideline can be a guideline object or an integer representing the guideline index.

removeLayer(name)

Remove the layer with name from the font.

>>> font.removeLayer("My Layer 3")

round()

Round all approriate data to integers.

>>> font.round()

This is the equivalent of calling the round method on:

  • info
  • kerning
  • the default layer
  • font-level guidelines

This applies only to the default layer.

swapLayerNames(layerName, otherLayerName)

Assign layerName to the layer currently named otherLayerName and assign the name otherLayerName to the layer currently named layerName.

>>> font.swapLayerNames("before drawing revisions", "after drawing revisions")

__contains__(name)

Test if the layer contains a glyph with name. :

>>> "A" in layer
True

insertGlyph(glyph, name=None)

Insert glyph into the layer. :

>>> glyph = layer.insertGlyph(otherGlyph, name="A")

This method is deprecated. BaseFont.__setitem__ instead.

keys()

>>> layer.keys()
["B", "C", "A"]

The order of the glyphs is undefined.

removeGlyph(name)

>>> layer.removeGlyph("A")

This method is deprecated. BaseFont.__delitem__ instead.
