Composite Glyphs - Glyph Member Properties
When you have opened a composite glyph in the Glyph Edit window, you can modify the properties of each composite glyph member. Either double-click a Glyph Member or right-click it and then select Glyph Member Properties.
In the Composite Glyph Properties window you can modify the position, scale, rotation, transformation and special flags of the selected member. Use the Previous and Next buttons to walk through the members.
The Flags consist of a set of fields:
Use this glyphs metrics
If set, this forces the advance width and left side bearing (and right side bearing) for the composite to be equal to those from this original glyph. This works for hinted and unhinted characters. Only one member can have this option selected. Without this flag, the actual left side bearing and right side bearing of the composite glyph will be used.
Round xy to grid
Round the x and y offsets.
This bit is reserved/ obsolete. Do not set it.
Used by Apple in GX fonts.
Scaled component offset
Composite designed to have the component offset scaled (designed for Apple rasterizer).
Unscaled component offset
Composite designed not to have the component offset scaled (designed for the Microsoft TrueType rasterizer).
Note that the behavior of the Use this glyphs metrics operation is undefined for rotated composite components.
