		PCLT - PCL 5 Table The 'PCLT' table is strongly discouraged for OpenTypeTM fonts with TrueType outlines. Extra information on many of these fields can be found in the HP PCL 5 Printer Language Technical Reference Manual available from Hewlett-Packard Boise Printer Division. The format for the table is: Type Name of Entry FIXED Version ULONG FontNumber USHORT Pitch USHORT xHeight USHORT Style USHORT TypeFamily USHORT CapHeight USHORT SymbolSet CHAR Typeface[16] CHAR CharacterComplement[8] CHAR FileName[6] CHAR StrokeWeight CHAR WidthType BYTE SerifStyle BYTE Reserved (pad) Version Table version number 1.0 is represented as 0x00010000. FontNumber This 32-bit number is segmented in two parts. The most significant bit indicates native versus converted format. Only font vendors should create fonts with this bit zeroed. The 7 next most significant bits are assigned by Hewlett-Packard Boise Printer Division to major font vendors. The least significant 24 bits are assigned by the vendor. Font vendors should attempt to insure that each of their fonts are marked with unique values. Code Vendor A Adobe Systems B Bitstream Inc. C Agfa Corporation H Bigelow & Holmes L Linotype Company M Monotype Typography Ltd. Pitch The width of the space in FUnits (FUnits are described by the unitsPerEm field of the 'head' table). Monospace fonts derive the width of all characters from this field. xHeight The height of the optical line describing the height of the lowercase x in FUnits. This might not be the same as the measured height of the lowercase x. Style The most significant 6 bits are reserved. The 5 next most significant bits encode structure. The next 3 most significant bits encode appearance width. The 2 least significant bits encode posture. Structure (bits 5-9) 0 Solid (normal, black) 1 Outline (hollow) 2 Inline (incised, engraved) 3 Contour, edged (antique, distressed) 4 Solid with shadow 5 Outline with shadow 6 Inline with shadow 7 Contour, or edged, with shadow 8 Pattern filled 9 Pattern filled #1 (when more than one pattern) 10 Pattern filled #2 (when more than two patterns) 11 Pattern filled #3 (when more than three patterns) 12 Pattern filled with shadow 13 Pattern filled with shadow #1 (when more than one pattern or shadow) 14 Pattern filled with shadow #2 (when more than two patterns or shadows) 15 Pattern filled with shadow #3 (when more than three patterns or shadows) 16 Inverse 17 Inverse with border 18-31 reserved Width (bits 2-4) 0 normal 1 condensed 2 compressed, extra condensed 3 extra compressed 4 ultra compressed 5 reserved 6 expanded, extended 7 extra expanded, extra extended Posture (bits 0-1) 0 upright 1 oblique, italic 2 alternate italic (backslanted, cursive, swash) 3 reserved TypeFamily The 4 most significant bits are font vendor codes. The 12 least significant bits are typeface family codes. Both are assigned by HP Boise Division. Vendor Codes (bits 12-15) 0 reserved 1 Agfa Corporation 2 Bitstream Inc. 3 Linotype Company 4 Monotype Typography Ltd. 5 Adobe Systems 6 font repackagers 7 vendors of unique typefaces 8-15 reserved CapHeight The height of the optical line describing the top of the uppercase H in FUnits. This might not be the same as the measured height of the uppercase H. SymbolSet The most significant 11 bits are the value of the symbol set "number" field. The value of the least significant 5 bits, when added to 64, is the ASCII value of the symbol set "ID" field. Symbol set values are assigned by HP Boise Division. Unbound fonts, or "typefaces" should have a symbol set value of 0. See the PCL 5 Printer Language Technical Reference Manual or the PCL 5 Comparison Guide for the most recent published list of codes. Examples   PCL decimal Windows 3.1 "ANSI" 19U 629 Windows 3.0 "ANSI" 9U 309 Adobe "Symbol" 19M 621 Macintosh 12J 394 PostScript ISO Latin 1 11J 362 PostScript Std. Encoding 10J 330 Code Page 1004 9J 298 DeskTop 7J 234 TypeFace This 16-byte ASCII string appears in the "font print" of PCL printers. Care should be taken to insure that the base string for all typefaces of a family are consistent, and that the designators for bold, italic, etc. are standardized. Example  Times New    Times New  Bd  Times New  It  Times New  BdIt  Courier New    Courier New  Bd  Courier New  It  Courier New  BdIt CharacterComplement This 8-byte field identifies the symbol collections provided by the font, each bit identifies a symbol collection and is independently interpreted. Symbol set bound fonts should have this field set to all F's (except bit 0). Example DOS/PCL Complement 0xFFFFFFFF003FFFFE Windows 3.1 "ANSI" 0xFFFFFFFF37FFFFFE Macintosh 0xFFFFFFFF36FFFFFE ISO 8859-1 Latin 1 0xFFFFFFFF3BFFFFFE ISO 8859-1,2,9 Latin 1,2,5 0xFFFFFFFF0BFFFFFE The character collections identified by each bit are as follows: 31 ASCII (supports several standard interpretations) 30 Latin 1 extensions 29 Latin 2 extensions 28 Latin 5 extensions 27 Desktop Publishing Extensions 26 Accent Extensions (East and West Europe) 25 PCL Extensions 24 Macintosh Extensions 23 PostScript Extensions 22 Code Page Extensions The character complement field also indicates the index mechanism used with an unbound font. Bit 0 must always be cleared when the font elements are provided in Unicode order. FileName This 6-byte field is composed of 3 parts. The first 3 bytes are an industry standard typeface family string. The fourth byte is a treatment character, such as R, B, I. The last two characters are either zeroes for an unbound font or a two character mnemonic for a symbol set if symbol set found. Examples  TNRR00 Times New (text weight, upright)  TNRI00 Times New Italic  TNRB00 Times New Bold  TNRJ00 Times New Bold Italic  COUR00 Courier  COUI00 Courier Italic  COUB00 Courier Bold  COUJ00 Courier Bold Italic Treatment Flags R Text, normal, book, etc. I Italic, oblique, slanted, etc. B Bold J Bold Italic, Bold Oblique D Demibold E Demibold Italic, Demibold Oblique K Black G Black Italic, Black Oblique L Light P Light Italic, Light Oblique C Condensed A Condensed Italic, Condensed Oblique F Bold Condensed H Bold Condensed Italic, Bold Condensed Oblique S Semibold (lighter than demibold) T Semibold Italic, Semibold Oblique other treatment flags are assigned over time. StrokeWeight This signed 1-byte field contains the PCL stroke weight value. Only values in the range -7 to 7 are valid: -7 Ultra Thin -6 Extra Thin -5 Thin -4 Extra Light -3 Light -2 Demilight -1 Semilight 0 Book, text, regular, etc. 1 Semibold (Medium, when darker than Book) 2 Demibold 3 Bold 4 Extra Bold 5 Black 6 Extra Black 7 Ultra Black, or Ultra Type designers often use interesting names for weights or combinations of weights and styles, such as Heavy, Compact, Inserat, Bold No. 2, etc. PCL stroke weights are assigned on the basis of the entire family and use of the faces. Typically, display faces don't have a "text" weight assignment. WidthType This signed 1-byte field contains the PCL appearance width value. The values are not directly related to those in the appearance with field of the style word above. Only values in the range -5 to 5 are valid. -5 Ultra Compressed -4 Extra Compressed -3 Compressed, or Extra Condensed -2 Condensed 0 Normal 2 Expanded 3 Extra Expanded SerifStyle This signed 1-byte field contains the PCL serif style value. The most significant 2 bits of this byte specify the serif/sans or contrast/monoline characterisitics of the typeface. Bottom 6 bit values: 0 Sans Serif Square 1 Sans Serif Round 2 Serif Line 3 Serif Triangle 4 Serif Swath 5 Serif Block 6 Serif Bracket 7 Rounded Bracket 8 Flair Serif, Modified Sans 9 Script Nonconnecting 10 Script Joining 11 Script Calligraphic 12 Script Broken Letter Top 2 bit values: 0 reserved 1 Sans Serif/Monoline 2 Serif/Contrasting 3 reserved Reserved Should be set to zero. this page was last updated 21 August 2002 © 1998 Microsoft Corporation.
