Chapter 1. Overview Fonts Negative Y offset for f 1 - 12 IJPDS Formats Category II fonts allow the printing of a line at any angle as shown in Figure 1.12. As seen for the character A, the characters must be defined at an angle in their bounding boxes. The character escapement values are then used to produce angle printing. Figure 1.12 Vertical, right-to-left, and angle printing Vertical printing X escapement = 0 Y escapement = n Character offsets let you design fonts using a baseline method. This method, illustrated in Figure 1.12, uses a negative Y offset for each character to place the character above the cursor position in the page buffer. Therefore, a baseline for all characters can be maintained. As shown in the illustration, the baseline method is useful when there is the possibility of changing font sizes in a line. The f character in Figure 1.13 is larger than the other characters but maintains the same baseline. Figure 1.13 Baseline font design Regular and Super Fonts Right-to-left printing X escapement = negative n Y escapement = 0 Angle printing Baseline X character escapement Y character escapement Both category I and category II fonts can be regular or super. A regular font is a single-byte font that allows each character to be accessed with a 1-byte code. For example, a 1-byte code of hexadecimal 41 is used to access the text character A in an ASCII text font. A super font is a doublebyte font that allows each character to be accessed with a 2-byte code. Super fonts are required for languages with more than 256 characters in a font. The number of regular and super fonts, including both category I and category II, in an IJPDS job file cannot exceed 255.
Definition Records for Category I Fonts Chapter 1. Overview Fonts Regular fonts are described in the IJPDS job file using font definition records (FDR) and character definition records (CDR). Each font has one FDR that provides a general description of the font. Immediately following each FDR, up to 256 CDRs (plus a default CDR) define the bitmaps for each character in the font. For super fonts, the first byte of the 2-byte code identifies a subfont of the super font and the second byte identifies the character in that subfont. Super fonts are described in the IJPDS job file using super font definition (SFD) records. Each super font has one SFD that provides a general description of the font. Immediately following the SFD, up to 256 FDRs describe each subfont in the super font. Immediately following each FDR, up to 256 CDRs (plus a default CDR) define the bitmaps for each character in the subfont. Since there is no way for the Data Station to tell whether a subsequent FDR begins a new single-byte font or another subfont to the super font it has been loading, any SFD-style (category I) super fonts for a RIP must be loaded after all single-byte FDR-style fonts for that RIP. (This is not a problem with category II fonts as SFMs do not have subfonts.) The preferred method of specifying a default character for the entire super font is to include one default CDR immediately after the SFD, rather than including a default CDR after each FDR. Definition Records for Category II Fonts Regular fonts are described in the IJPDS job file using font definition with metrics (FDM) records and character definition with metrics (CDM) records or compressed character definition (CCD) records. Each font has one FDM that provides a general description of the font. Immediately following each FDM, up to 256 CDMs or CCDs (plus a default CDM or CCD) define the bitmaps for each character in the font. For super fonts, the 2-byte code identifies one of up to 65,536 characters in the super font. Super fonts are described in the IJPDS job file using super font with metrics (SFM) records. Each super font has one SFM that provides a general description of the font. Immediately following the SFM, up to 65,536 CDMs or CCDs (plus a default CDM or CCD) define the bitmaps for each character in the super font. Current Font In Chapter 4, the descriptions for some record fields refer to the “current font”. The current font is the font currently in effect. It is the last font specified, in execution order, by an IJPDS job file record. Notice that execution order of records determines the current font rather than the order of records in the IJPDS job file. Because some records that specify fonts occur in fixed files, they may be executed in a different order than the order in which they appear in the IJPDS job file. The current font is set to a starting or default font at the start of each new document. Refer to the description for the SOD or SDC record in Chapter 4. Reference Guide 1 - 13
