Microsoft word 2017 for mac adjust kerning

If a font doesn't support the kern table, the method returns zeroes for the glyph advance adjustments. GetKerningPairAdjustments allows you to input an array of glyph indices and DirectWrite returns an array of glyph advance adjustments. The IDWriteFontFace1 also has a method that allows you to get access to the kerning pair adjustments for glyph indices. This method returns a bool value of 1 if the font supports kerning pairs. If you want to know whether or not a font supports pair kerning, you can use the IDWriteFontFace1::HasKerningPairs method. The character advances between pairs of characters that the font kerns are stored in the kern table and DirectWrite parses that table and returns the information to you through the kerning APIs.

The kerning in this example makes the word more readable and more natural. The original text without kerning is on the second line. As you can see from the red boxes around the characters, there is more spacing applied between the first four letters, while the R on the end has more space before it. The word AVATAR on the top line is kerned in order to make the word look more natural. The important difference between kerning and character spacing is the fact that letter spacing is agnostic to the text it spaces, while kerning is used in certain situations between certain pairs of characters as defined in the font. Specific spacing between sets of characters can increase readability and make text look better. Kerning is the contextual spacing adjustment between pairs or triplets of letters. The method returns the modified glyph advances and a DWRITE_GLYPH_OFFSET enumeration with the new offsets to the origin of each glyph. This method allows you to provide ApplењњharacterSpacing with the leading and trailing spacing, minimum advance width, length of the cluster map, number of glyphs, mapping from character ranges to glyphs, and advance width of each glyph if you use a custom layout. Use this method if you require a custom text layout in order to have advanced control over your layout. If you are using a custom layout, DirectWrite has support for setting character spacing with IDWriteTextAnalyzer1::ApplењњharacterSpacing. The SetCharacterSpacing method takes in the amount of space you want before and after the character, the minimum advance allowed, and a DWRITE_TEXT_RANGE that defines the range to apply the spacing. Use the SetCharacterSpacing on a DWriteTextLayout1 interface to apply your own character spacing to the text in the layout. Use the GetCharacterSpacing method to determine the current character spacing and it returns the current character, the spacing before and after the character, the minimum advance width, and a DWRITE_TEXT_RANGE structure that contains information about the starting position and length of the remaining text. If you are using the DirectWrite layout, you can use the IDWriteTextLayout1::GetCharacterSpacing and IDWriteTextLayout1::SetCharacterSpacing methods for this purpose. Starting with WindowsВ 8, DirectWrite adds these methods here to control the spacing of characters in your text. The second line increases character spacing, and the third line decreases the character spacing. The first line applies no tracking to the text. Character spacingД¬haracter spacing, also known as 'tracking', is the spacing between characters in a run of text.

Starting with WindowsВ 8, DirectWrite provides a number of features that allow you to control basic typographic, layout, and spacing features, such as character spacing, pair kerning, and justification.
