#Kozuka gothic fonts driver#

Kozuka Gothic provides a clear image common to Kozuka Mincho, but also gives the visual strength needed for a Gothic typeface. This allows the font vendor to do special handling of the mark combination when doing further processing without requiring larger contextual rules.The Kozuka Gothic typeface family, composed of six different weights to cover various uses ranging from body text composition to headlines, have now been completed as OpenType fonts. In Arabic it might be preferred to combine the shadda with fatha (0x0651, 0x064E) into a ligature before processing shapes. These two glyphs can then be correctly placed using GPOS. To avoid multiple glyph variants to fit all base glyphs, the character is decomposed into two glyphs.a dot above and a dot below. In Syriac, the character 0x0732 is a combining mark that has a dot above AND a dot below the base character.

The feature should be processed as the first feature processed, and should be processed only when it is called. This feature permits such composition/decompostion. Additionally, it may be preferable to compose two characters into a single glyph for better glyph processing. Proportional- or half-width Latin and half-width katakana characters are rotated 90 degrees clockwise for vertical writing.įunction: To minimize the number of glyph alternates, it is sometimes desired to decompose a character into two glyphs. In order for kerning to produce identical results as well, developers must ensure that the Vertical Kerning (vkrn) feature record kern values between the rotated glyphs that are the same as kern values between their corresponding upright glyphs in the Kerning (kern) feature. The vendor may however set it to head.unitsPerEm, to prevent overlap during font proofing tests, for example.) Thus, proportional-width glyphs with rotated forms in the vrt2 feature will appear identically spaced in both vertical and horizontal writing. (The horizontal advance of the rotated glyph may be set to any value, since the glyph is intended only for vertical writing use. A rotated glyph must be designed such that its top side bearing and vertical advance as recorded in the Vertical Metrics ('vmtx') table are identical to the left side bearing and horizontal advance, respectively, of the corresponding upright glyph as recorded in the Horizontal Metrics ('hmtx') table. The predecessor feature, vert, is ignored.

ATM/NT 4.1 and the Windows 2000 OTF driver impose the following requirements for an OpenType font with CFF outlines to be used for vertical writing: the vrt2 feature must be present in the GSUB table, it must comprises a single lookup of LookupType 1 and LookupFlag 0, and the lookup must have a single subtable.

Note that these are a superset of the glyphs covered in the vert table.
