All glyphs are # handled as if they fill that combined bounding box. # (- ScaleGroupsVert: Removed with this commit) # # The ScaleGlyph method: You set 'ScaleGlyph' to the unicode of the reference glyph. # Note that there can be only one per patch-set. # Additionally you set 'GlyphsToScale' that contains all the glyphs that shall be # handled (scaled) like the reference glyph. # It is a List of: ((glyph code) or (tuple of two glyph codes that form a closed range)) # 'GlyphsToScale': [ # 0x0100, 0x0300, 0x0400, # The single glyphs 0x0100, 0x0300, and 0x0400 # (0x0200, 0x0210), # All glyphs 0x0200 to 0x0210 including both 0x0200 and 0x0210 # ]} # If you want to not only scale but also shift as the refenerce glyph you give the # data as 'GlyphsToScale+'.
