| 3354 | 52 /* #### TO DO #### |
| 53 . The "x-xft-*" and "x_xft_*" nomenclature is mostly redundant, especially | |
| 54 if we separate X fonts from Xft fonts, and use fontconfig more generally. | |
| 55 . We should support the most recent Xft first, old Xft libraries later. | |
| 56 . We may (think about it) wish to use fontconfig generally, even if we're | |
| 57 not using Xft. Either way, names that are really from fontconfig should | |
| 58 use the Fc* namespace. | |
| 59 . Mule-ize this file. | |
| 60 . Separate X Font Struct ops from Xft Font ops; give precedence to Xft but | |
| 61 allow fallback to X. | |
| 62 . Push decisions about font choice, defaults, fallbacks to Lisp; if we | |
| 63 really need efficiency, can reimplement in C later. | |
| 64 . Implement symbols interned in this file in the Q* namespace. | |
| 65 . Implement FcMatrix (Lisp vector). | |
| 66 . Implement FcCharSets (Lisp chartable? For implementation hints, see | |
| 67 FcCharSetFirstPage and FcCharSetNextPage). | |
| 68 . Implement FcConfigs. | |
| 69 DONE | |
| 70 . Fontconfig fontnames are encoded in UTF-8. | |

| 172 fontconfig assumes that objects (property names) are statically allocated, | |

| 345 From PATTERN, extract PROPERTY for the ID'th member, of type TYPE. | |
| 346 | |
| 347 PATTERN is an Xft (fontconfig) pattern object. | |
| 348 PROPERTY is a string naming an fontconfig font property. | |
| 349 Optional ID is a nonnegative integer indexing the list of values for PROPERTY | |
| 350 stored in PATTERN, defaulting to 0 (the first value). | |
| 351 Optional TYPE is a symbol, one of 'string, 'boolean, 'integer, 'float, | |
| 352 'double, 'matrix, 'charset, or 'void, corresponding to the FcValue types. | |
| 353 ('float is an alias for 'double). | |
| 354 | |
| 355 The Lisp types returned will conform to TYPE: | |
| 356 string string | |
| 357 boolean `t' or `nil' | |
| 358 integer integer | |
| 359 double (float) float | |
| 360 matrix not implemented | |
| 361 charset not implemented | |
| 362 void not implemented | |
| 363 | |
| 364 Symbols with names of the form "fc-result-DESCRIPTION" are returned when | |
| 365 the desired value is not available. These are | |
| 366 | |
| 367 fc-result-type-mismatch the value found has an unexpected type | |
| 368 fc-result-no-match there is no such attribute | |
| 369 fc-result-no-id there is no value for the requested ID | |
| 370 | |
| 371 The types of the following standard properties are predefined by fontconfig. | |
| 372 The symbol 'fc-result-type-mismatch will be returned if the object exists but | |
| 373 TYPE does not match the predefined type. It is best not to specify a type | |
| 374 for predefined properties, as a mistake here ensures error returns on the | |
| 375 correct type. | |
| 376 | |
| 377 Each standard property has a convenience accessor defined in fontconfig.el, | |
| 378 named in the form "fc-pattern-get-PROPERTY". The convenience functions are | |
| 379 preferred to `fc-pattern-get' since a typo in the string naming a property | |
| 380 will result in a silent null return, while a typo in a function name will | |
| 381 usually result in a compiler or runtime \"not fboundp\" error. You may use | |
| 382 `defsubst' to define convenience functions for non-standard properties. | |
| 383 | |
| 384 family String Font family name | |
| 385 style String Font style. Overrides weight and slant | |
| 386 slant Int Italic, oblique or roman | |
| 387 weight Int Light, medium, demibold, bold or black | |
| 388 size Double Point size | |
| 389 aspect Double Stretches glyphs horizontally before hinting | |
| 390 pixelsize Double Pixel size | |
| 391 spacing Int Proportional, monospace or charcell | |
| 392 foundry String Font foundry name | |
| 393 antialias Bool Whether glyphs can be antialiased | |
| 394 hinting Bool Whether the rasterizer should use hinting | |
| 395 verticallayout Bool Use vertical layout | |
| 396 autohint Bool Use autohinter instead of normal hinter | |
| 397 globaladvance Bool Use font global advance data | |
| 398 file String The filename holding the font | |
| 399 index Int The index of the font within the file | |
| 400 ftface FT_Face Use the specified FreeType face object | |
| 401 rasterizer String Which rasterizer is in use | |
| 402 outline Bool Whether the glyphs are outlines | |
| 403 scalable Bool Whether glyphs can be scaled | |
| 404 scale Double Scale factor for point->pixel conversions | |
| 405 dpi Double Target dots per inch | |
| 406 rgba Int unknown, rgb, bgr, vrgb, vbgr, none - subpixel geometry | |
| 407 minspace Bool Eliminate leading from line spacing | |
| 408 charset CharSet Unicode chars encoded by the font | |
| 409 lang String List of RFC-3066-style languages this font supports | |
| 410 | |
| 411 The FT_Face, Matrix, CharSet types are unimplemented, so the corresponding | |
| 412 properties are not accessible from Lisp at this time. If the value of a | |
| 413 property returned has type FT_Face, FcCharSet, or FcMatrix, | |
| 414 `fc-result-type-mismatch' is returned. | |
