In - particular, the X server and font server should be able to both - use the library to access disk based fonts, and to communicate - with a font server. By providing a general library, we hoped to - avoid duplicating code between the X server and font server. - - - - Another requirement is that the X server (or even a font server) - be able to continue servicing requests from other clients while - awaiting a response from the font server on behalf of one client. - This is the strongest requirement placed on the font library, and - has warped the design in curious ways. Because both the X server - and font server are single threaded, the font library must not - suspend internally, rather it returns an indication of suspension - to the application which continues processing other things, until - the font data is ready, at which time it restarts the suspended - request. - - - - Because the code for reading and manipulating bitmap font data is - used by the font applications mkfontdir and - bdftopcf, the font library includes - bitmap-font specific interfaces which those applications use, - instead of the more general interfaces used by the X and font - servers, which are unaware of the source of the font data. - These routines will be refered to as the bitmap font access - methods. - - - - - - - General Font Library Interface details. - - - - To avoid collision between the #define name space for errors, the Font - library defines a new set of return values: - - - -#define AllocError 80 -#define StillWorking 81 -#define FontNameAlias 82 -#define BadFontName 83 -#define Suspended 84 -#define Successful 85 -#define BadFontPath 86 -#define BadCharRange 87 -#define BadFontFormat 88 -#define FPEResetFailed 89 - - - - Whenever a routine returns Suspended, - the font library will notify the caller (via the ClientSignal - interface described below) who should then reinvoke the same routine - again with the same arguments. - - - - - - - Font Path Elements - - - - At the center of the general font access methods used by X and - xfs is the Font Path Element data structure. - Like most structures in the X server, this contains a collection - of data and some function pointers for manipulating this data: - - - -/* External view of font paths */ -typedef struct _FontPathElement { - int name_length; - char *name; - int type; - int refcount; - pointer private; -} FontPathElementRec, *FontPathElementPtr; - -typedef struct _FPEFunctions { - int (*name_check) ( /* name */ ); - int (*init_fpe) ( /* fpe */ ); - int (*reset_fpe) ( /* fpe */ ); - int (*free_fpe) ( /* fpe */ ); - int (*open_font) ( /* client, fpe, flags, - name, namelen, format, - fid, ppfont, alias */ ); - int (*close_font) ( /* pfont */ ); - int (*list_fonts) ( /* client, fpe, pattern, - patlen, maxnames, paths */ ); - int (*start_list_fonts_with_info) ( - /* client, fpe, name, namelen, - maxnames, data */ ); - int (*list_next_font_with_info) ( - /* client, fpe, name, namelen, - info, num, data */ ); - int (*wakeup_fpe) ( /* fpe, mask */ ); - int (*client_died) ( /* client, fpe */ ); -} FPEFunctionsRec, FPEFunctions; - - - - The function pointers are split out from the data structure to - save memory; additionally, this avoids any complications when - initializing the data structure as there would not be any way - to discover the appropriate function to call (a chicken and - egg problem). - - - - When a font path type is initialized, it passes the function - pointers to the server which are then stored in an - FPEFunctionsRec. Each function is - described below in turn. - - - - - (*name_check) - - - - Each new font path member is passed to this function; if - the return value is Successful, then - the FPE recognises the format of the string. This does not - guarantee that the FPE will be able to successfully use this - member. For example, the disk-based font directory file - fonts.dir may be corrupted, this will - not be detected until the font path is initialized. This - routine never returns Suspended. - - - - - - (*init_fpe) - - - - Initialize a new font path element. This function prepares - a new font path element for other requests: the disk font - routine reads the fonts.dir and - fonts.alias files into the internal - format, while the font server routine connects to the - requested font server and prepares for using it. This - routine returns Successful if - everything went OK, otherwise the return value indicates the - source of the problem. This routine never returns - Suspended. - - - - - - (*reset_fpe) - - - - When the X font path is reset, and some of the new members - are also in the old font path, this function is called to - reinitialize those FPEs. This routine returns - Successful if everything went OK. It - returns FPEResetFailed if (for some - reason) the reset failed, and the caller should remove the - old FPE and simply create a new one in its place. This is - used by the disk-based fonts routine as resetting the - internal directory structures would be more complicated than - simply having destroying the old and creating a new. - - - - - - (*free_fpe) - - - - When the server is finished with an FPE, this function is - called to dispose of any internal state. It should return - Successful, unless something terrible - happens. - - - - - - (*open_font) - - - - This routine requests that a font be opened. The client argument is used by the - font library only in connection with suspending/restarting - the request. The flags - argument specifies some behaviour for the library and can be - any of: - - - -/* OpenFont flags */ -#define FontLoadInfo 0x0001 -#define FontLoadProps 0x0002 -#define FontLoadMetrics 0x0004 -#define FontLoadBitmaps 0x0008 -#define FontLoadAll 0x000f -#define FontOpenSync 0x0010 - - - - The various fields specify which portions of the font should - be loaded at this time. When FontOpenSync - is specified, this routine will not return until all of the - requested portions are loaded. Otherwise, this routine may - return Suspended. When the presented - font name is actually an alias for some other font name, - FontNameAlias is returned, and the - actual font name is stored in the location pointed to by the - alias argument as a - null-terminated string. - - - - - - (*close_font) - - - - When the server is finished with a font, this routine - disposes of any internal state and frees the font data - structure. - - - - - - (*list_fonts) - - - - The paths argument is - a data structure which will be filled with all of the font names - from this directory which match the specified - pattern. At - most maxnames will be added. - This routine may return Suspended. - - - - - - (*start_list_fonts_with_info) - - - - This routine sets any internal state for a verbose listing of - all fonts matching the specified pattern. This routine may - return Suspended. - - - - - - (*list_next_font_with_info) - - - - To avoid storing huge amounts of data, the interface for - ListFontsWithInfo allows the server to get one reply at a time - and forward that to the client. When the font name returned - is actually an alias for some other font, - FontNameAlias will be returned. The - actual font name is return instead, and the font alias which - matched the pattern is returned in the location pointed to by - data as a null-terminated string. The caller can then get the - information by recursively listing that font name with a - maxnames of 1. When Successful is - returned, the matching font name is returned, and a - FontInfoPtr is stored in the location pointed to by - data. - Data must be initialized - with a pointer to a FontInfoRec allocated by the caller. When the - pointer pointed to by data - is not left pointing at that storage, the caller mustn't free the - associated property data. This routine may return - Suspended. - - - - - - (*wakeup_fpe) - - - - Whenever an FPE function has returned - Suspended, this routine is called - whenever the application wakes up from waiting for input - (from select - 2). This - mask argument should be - the value returned from select(2). - - - - - - (*client_died) - - - - When an FPE function has returned Suspended - and the associated client is being destroyed, this function - allows the font library to dispose of any state associated - with that client. - - - - - - - Fonts - - - - The data structure which actually contains the font information has - changed significantly since previous releases; it now attempts to - hide the actual storage format for the data from the application, - providing accessor functions to get at the data. This allows a - range of internal details for different font sources. The structure - is split into two pieces, so that ListFontsWithInfo can share - information from the font when it has been loaded. The - FontInfo structure, then, contains only - information germane to LFWI. - - - -typedef struct _FontInfo { - unsigned short firstCol; /* range of glyphs for this font */ - unsigned short lastCol; - unsigned short firstRow; - unsigned short lastRow; - unsigned short defaultCh; /* default character index */ - unsigned int noOverlap:1; /* no combination of glyphs overlap */ - unsigned int terminalFont:1; /* Character cell font */ - unsigned int constantMetrics:1; /* all metrics are the same */ - unsigned int constantWidth:1; /* all character widths are the same*/ - unsigned int inkInside:1; /* all ink inside character cell */ - unsigned int inkMetrics:1; /* font has ink metrics */ - unsigned int allExist:1; /* no missing chars in range */ - unsigned int drawDirection:2; /* left-to-right/right-to-left*/ - unsigned int cachable:1; /* font needn't be opened each time*/ - unsigned int anamorphic:1; /* font is strangely scaled */ - short maxOverlap; /* maximum overlap amount */ - short pad; /* unused */ - xCharInfo maxbounds; /* glyph metrics maximums */ - xCharInfo minbounds; /* glyph metrics minimums */ - xCharInfo ink_maxbounds; /* ink metrics maximums */ - xCharInfo ink_minbounds; /* ink metrics minimums */ - short fontAscent; /* font ascent amount */ - short fontDescent; /* font descent amount */ - int nprops; /* number of font properties */ - FontPropPtr props; /* font properties */ - char *isStringProp; /* boolean array */ -} FontInfoRec, *FontInfoPtr; - - - - The font structure, then, contains a font info record, the format of - the bits in each bitmap and the functions which access the font - records (which are stored in an opaque format hung off of - fontPrivate). - - - -typedef struct _Font { - int refcnt; - FontInfoRec info; - char bit; /* bit order: LSBFirst/MSBFirst */ - char byte; /* byte order: LSBFirst/MSBFirst */ - char glyph; /* glyph pad: 1, 2, 4 or 8 */ - char scan; /* glyph scan unit: 1, 2 or 4 */ - fsBitmapFormat format; /* FS-style format (packed) */ - int (*get_glyphs) ( /* font, count, chars, encoding, count, glyphs */ ); - int (*get_metrics) ( /* font, count, chars, encoding, count, glyphs */ ); - int (*get_bitmaps) ( /* client, font, flags, format, - flags, nranges, ranges, data_sizep, - num_glyphsp, offsetsp, glyph_datap, - free_datap */ ); - int (*get_extents) ( /* client, font, flags, nranges, - ranges, nextentsp, extentsp */); - void (*unload_font) ( /* font */ ); - FontPathElementPtr fpe; /* FPE associated with this font */ - pointer svrPrivate; /* X/FS private data */ - pointer fontPrivate; /* private to font */ - pointer fpePrivate; /* private to FPE */ - int maxPrivate; /* devPrivates (see below) */ - pointer *devPrivates; /* ... */ -} FontRec, *FontPtr; - - - - Yes, there are several different private pointers in the - Font structure; they were added - haphazardly until the devPrivate pointers were added. Future - releases may remove some (or all) of the specific pointers, - leaving only the devPrivatesmechanism. - - - - There are two similar interfaces implemented - - get_glyphs/get_metrics - and - get_bitmaps/get_extents. - Too little time caused the font-server specific interfaces to - be placed in the font library (and portions duplicated in each - renderer) instead of having them integrated into the font server - itself. This may change. The X server uses only - get_glyphs/get_metrics, - and those will not change dramatically. Each of the routines - is described below. - - - - - (*get_glyphs) - - - - This routine returns CharInfoPtrs - for each of the requested characters in the font. If the - character does not exist in the font, the default character - will be returned, unless no default character exists in - which case that character is skipped. Thus, the number of - glyphs returned will not always be the same as the number of - characters passed in. - - - - - - (*get_metrics) - - - - This is similar to (*get_glyphs) - except that pointers to xCharInfo - structures are returned, and, if the font has ink metrics, - those are returned instead of the bitmap metrics. - - - - - - (*get_bitmaps) - - - - This packs the glyph image data in the requested - format and returns it. The - ranges/nranges - argument specify the set of glyphs from the font to pack together. - - - - - - (*get_extents) - - - - This returns the metrics for the specified font from the - specified ranges. - - - - - - - (*unload_font) - - - - This is called from the FPE routine - (*close_font), and so should not ever be - called from the application. - - - - - - maxPrivate - - - - When initializing a new font structure, - maxPrivate should be set to -1 so - that the FontSetPrivate() macro works - properly with an index of 0. Initializing - maxPrivate to 0 can cause - problems if the server tries to set something at index 0. - - - -

The + ranges/nranges + argument specify the set of glyphs from the font to pack together. + + + + + + (*get_extents) + + + + This returns the metrics for the specified font from the + specified ranges. + + + + + + + (*unload_font) + + + + This is called from the FPE routine + (*close_font), and so should not ever be + called from the application. + + + + + + maxPrivate + + + + When initializing a new font structure, + maxPrivate should be set to -1 so + that the FontSetPrivate() macro works + properly with an index of 0. Initializing + maxPrivate to 0 can cause + problems if the server tries to set something at index 0. + + + +
