Other glyphs are # scaled by the same factor as this glyph. This is useful if you have one # 'biggest' glyph and all others should stay relatively in size. # Shifting in addition to scaling can be selected too (see below). # - ScaleGroups: # Here you specify a group of glyphs that should be handled together # with the same scaling and shifting. The basis for it is a 'combined # bounding box' of all glyphs in that group. All glyphs are handled as # if they fill that combined bounding box. # # 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+'. Note that only one set is used and the plus version is preferred. # # For the ScaleGroup method you define any number groups of glyphs and each group is # handled separately. The combined bounding box of all glyphs in the group is determined # and based on that the scale and shift for all the glyphs in the group. # You define the groups as value of 'ScaleGroups'. # It is a List of: ((lists of glyph codes) or (ranges of glyph codes)) # 'ScaleGroups': [ # [0x0100, 0x0300, 0x0400], # One group consists of glyphs 0x0100, 0x0300, and 0x0400 # range(0x0200, 0x0210 + 1), # Another group contains glyphs 0x0200 to 0x0210 incl. # # Note the subtle differences: tuple vs. range; closed vs open range; etc # See prepareScaleRules() for some more details. # For historic reasons ScaleGroups is sometimes called 'new method' and ScaleGlyph 'old'. # The codepoints mentioned here are symbol-font-codepoints.
