| Name | Description |
|---|---|
| CMap4 | CMap format 4: Segment mapping to delta values. The Windows standard format. |
| CMapTable | This table defines the mapping of character codes to the glyph index values used in the font. It may contain more than one subtable, in order to support more than one character encoding scheme. |
| ControlValueProgram | The Control Value Program consists of a set of TrueType instructions that will be executed whenever the font or point size or transformation matrix change and before each glyph is interpreted. Any instruction is legal in the CVT Program but since no glyph is associated with it, instructions intended to move points within a particular glyph outline cannot be used in the CVT Program. The name 'prep' is anachronistic. |
| ControlValueTable | This table contains a list of values that can be referenced by instructions. They can be used, among other things, to control characteristics for different glyphs. The length of the table must be an integral number of FWORD units. |
| FileExtensions | |
| FontData | Represents an Open Type Font font in memory. |
| FontData.OffsetTable | Represents the font offset table. |
| FontDataConfig | public configuration surface for the FontData loader |
| FontHeaderTable | This table gives global information about the font. The bounding box values should be computed using only glyphs that have contours. Glyphs with no contours should be ignored for the purposes of these calculations. |
| FontProgram | This table is similar to the CVT Program, except that it is only run once, when the font is first used. It is used only for FDEFs and IDEFs. Thus the CVT Program need not contain function definitions. However, the CVT Program may redefine existing FDEFs or IDEFs. |
| GlyphDataTable | This table contains information that describes the glyphs in the font in the TrueType outline format. Information regarding the rasterizer (scaler) refers to the TrueType rasterizer. http://www.microsoft.com/typography/otspec/glyf.htm |
| GlyphSubstitutionTable | This table contains information that describes the glyphs in the font in the TrueType outline format. Information regarding the rasterizer (scaler) refers to the TrueType rasterizer. |
| HorizontalHeaderTable | This table contains information for horizontal layout. The values in the minRightSidebearing, minLeftSideBearing and xMaxExtent should be computed using only glyphs that have contours. Glyphs with no contours should be ignored for the purposes of these calculations. All reserved areas must be set to 0. |
| HorizontalMetrics | |
| HorizontalMetricsTable | The type longHorMetric is defined as an array where each element has two parts: the advance width, which is of type USHORT, and the left side bearing, which is of type SHORT. These fields are in font design units. |
| IndexToLocationTable | The indexToLoc table stores the offsets to the locations of the glyphs in the font, relative to the beginning of the glyphData table. In order to compute the length of the last glyph element, there is an extra entry after the last valid index. |
| MaximumProfileTable | This table establishes the memory requirements for this font. Fonts with CFF data must use Version 0.5 of this table, specifying only the numGlyphs field. Fonts with TrueType outlines must use Version 1.0 of this table, where all data is required. Both formats of OpenType require a 'maxp' table because a number of applications call the Windows GetFontData() API on the 'maxp' table to determine the number of glyphs in the font. |
| NameTable | The naming table allows multilingual strings to be associated with the OpenTypeTM font file. These strings can represent copyright notices, font names, family names, style names, and so on. To keep this table short, the font manufacturer may wish to make a limited set of entries in some small set of languages; later, the font can be "localized" and the strings translated or added. Other parts of the OpenType font file that require these strings can then refer to them simply by their index number. Clients that need a particular string can look it up by its platform ID, character encoding ID, language ID and name ID. Note that some platforms may require single byte character strings, while others may require double byte strings. For historical reasons, some applications which install fonts perform version control using Macintosh platform (platform ID 1) strings from the 'name' table. Because of this, we strongly recommend that the 'name' table of all fonts include Macintosh platform strings and that the syntax of the version number (name id 5) follows the guidelines given in this document. |
| NameTable.NameRecord | |
| OS2Table | The OS/2 table consists of a set of metrics that are required in OpenType fonts. |
| OpenTypeDescriptor | The OpenType font descriptor. |
| PostScriptTable | This table contains additional information needed to use TrueType or OpenTypeTM fonts on PostScript printers. |
| TableDirectoryEntry | Represents an entry in the fonts table dictionary. |
| VerticalHeaderTable | |
| VerticalMetrics | |
| VerticalMetricsTable | The vertical metrics table allows you to specify the vertical spacing for each glyph in a vertical font. This table consists of either one or two arrays that contain metric information (the advance heights and top sidebearings) for the vertical layout of each of the glyphs in the font. |
