Only signigficant source code changes were + in dpost.utf (font.h, font.c, dpost.c). Added common/rune.[hc] so code + can be compiled elsewere. Remove RUNELIB in commmon/rune.h if fullrune(), + chartorune(), and runetochar() are available on your system. Original + DWB 3.3 dpost source is in directory dpost. You should select dpost or + dpost.utf in postscript.mk. Both compile and install a program called + dpost so don't pick both! + + 2: dpost can read old or UTF troff output. Default is whatever is assigned + to READING (file common/gen.h). You get one or the other, unless troff + tells dpost what encoding to use (currently x E UTF). + + 3: Most other translators passed bytes through and so only needed slightly + modified proglogues and a new encoding scheme (psencoding/UTF.enc). It + works for Latin1, but still needs a bit more attention. Prologue changes + were easy and only involved adding lines like, + + /show {show} bind def + /stringwidth {stringwidth} bind def + + Guarantees text procedures used in prologues aren't operators and can be + successfully redefined in UTF.enc. Unbinding means a small but probably + not noticeable speed penalty. You may not want to include those changes + on other system. + + 4: Operator redefinitions means dpost should work in it's own dictionary + (rather than userdict). Not implemented yet, but should be easy. Only + potential problem is with picture inclusion when dpost reads UTF.enc. + +------------------------ +Version 3.3.2 5/15/92 +------------------------ + + 1: postio now outputs all unrecognized status reports - primarly for spooler + accounting purposes. + + 2: The makefiles also enable the selection of alternate stream module names + for streams based DKHOST support in postio. + + 3: dpost now assumes the optional fifth token in a font mounting command + (e.g. x font 2 R /usr/me/font/R) is the full pathname of the font. troff + outputs the pathname when a .fp request contains a third argument that + begins with a / as in .fp 1 R /usr/me/font/R. + + 4: By request Latin1's - character has been changed from minus to the smaller + hyphen character. Added \(dq and \(bs (for " and \ characters) to devpost + and devLatin1 tables. Also added \(!! and \(?? to devpost tables. + + 5: Helvetica-Light and Helvetica-LightOblique tables are included as HL and + HK in devpost and devLatin1, even though fonts aren't generally available. + Also copy H to HM during an install of devpost and devLatin1 tables. + + 6: LH is a horizontally arranged color Lucent logo with text which replaces the AT&T logo. + LV is a vertically arranged monochrome AT&T logo with text. + FA is a horizontally arranged monochrome Lucent logo with text (low res.). + L1 is a monochrome AT&T logo, no text. + LA is a monochrome AT&T text. + + 7: Included L1 and LA outlines in devpost and devLatin1. Adjusted LA scaling + so size of "AT&T" matches what's in LV. Original PostScript came + from Matthijs Melchior. + + 8: Included the "symmetric clippath" version of roundpage.ps as Nroundpage.ps + in directory postscript/psfiles. Move it to roundpage.ps if you want it to + be the default. + + 9: Added a few lines of code to dpost for handling current implementation of + the portrait/landscape mode macros. + +10: The man page for download now documents the -r option and notes that -p + is for Unix 4.0 lp. + +------------------------ +Version 3.3.1 4/30/91 +------------------------ + + 1: buildtables stuff has been cleaned up and is now a user level command. + Uses shell.lib files that are installed with font tables. The devpost + tables were built on a version 47.0 PS-810. The devLatin1 tables were + built on a version 51.7 PS-820. + + 2: The devLatin1 tables provide support for the ISO Latin1 alphabet on + PostScript printers. + + 3: All translators support different text font encoding schemes using the + -E option and *.enc files installed in POSTLIB. The ISO Latin 1 alphabet + is supported with file /usr/lib/postscript/Latin1.enc. + + 4: printfont prints a table of the available (encoded) characters in one + or more PostScript fonts. It also understands the -E option. + + 5: grabit and hardcopy are two new programs that may be of interest to the + more serious PostScript programmer. grabit resembles ==, but produces + output that's usally easier to read. hardcopy redirects output from + PostScript file output operators (or procedures) to paper. It's useful + if you don't have direct access to a printer. + + 6: Prologues and programs are stored together. Other common PostScript files + are now in the psfiles directory. + +------------------------ +Verions 3.3 4/16/90 +------------------------ + + 1: The package is now included in DWB. Version numbers are a bit misleading. + The one in postscript.mk refers to the DWB package. + + 2: dpost (and troff) now read ASCII font tables. makedev and the old binary + format are gone. + + 3: The devpost directory came directly from the DWB package. The font tables + originally distributed with this package are in directory devopost. They + are not installed. If possible we recommend you use the devpost tables. + The old tables can be installed by adding devopost to the TARGETS list in + file postscript.mk. + + 4: dpost recognizes two new fields in font tables. Entries for the full + PostScript font look like, + + fontname Times-Roman + + The fontname field is helps manage host resident fonts, the DocumentFonts + comment, and is used to define font name abbreviations like the ones in + dpost.ps. A font table entry that looks like, + + named in prologue + + disables the runtime abbreviation for the font - dpost assumes it's already + in the prologue. + + 5: Extra font tables included in DWB 3.0's devpost font collection are in + directory devpost.add. They included here, but should probably not be + used. + + 6: Bracket building has been fixed and tested on a wide range of PostScript + printers. It will likely still not work on many clones. Real problem + appears to be with Adobe's braceleftbt character. + + 7: Most of the special tuning code for device emulation has been removed. + Emulation still works, but there may be cases where it's not as good as + earlier versions. + + 8: Several problems with color and reverse video printing have been fixed. + + 9: buildtables directory has been cleanup up. The template files in directory + buildtables/devpost.data were used to build the devpost tables. + +10: postplot and download are two new programs. postplot is for the System V + plot package only. Both were written for the Unix 4.0 lp package. + +11: postgif is also relatively new - it came from Chi Choy. + +12: The translators now rotate clockwise when printing in landscape mode. If + you want the old behavior set ROTATION to -1 in postscript.mk. + +13: forms.ps has been cleaned up some. Better behavior when you print 2 + landscape pages on one sheet. + +14: Handling of Datakit code for System V has been changed some. Makefiles + now expect to find libdk.a and dk.h in standard places (e.g /usr/lib and + /usr/include). Set DKHOST to TRUE in postscript.mk to get Datakit support + on System V. + + If you're stuck and need to have things behave as they did in the past + take a look at file postio/postio.mk. Define DKHOSTDIR and uncomment + three lines and the behavior should be close to what it was. + +15: Picture inclusion and color macros are gone. They're included in the DWB + package, and not here. + +------------------------ +Version 3.2 11/27/89 +------------------------ + + 1: Implemented height and slant requests in dpost. + + 2: Modified the behavior of all translators so save objects are no longer left + on the stack. The original implementation was a mistake and occasionally + (e.g. picture inclusion with forms.ps) resulted in invalid restores. + + 3: Fixed the mistake in the external declaration of mesg in postio/slowsend.c. + + 4: The malloc() call in postdmd (routine dimensions()) is only made if patterns + is positive. + + 5: Changed definition of De in draw.ps so savematrix is loaded with the CTM + whenever De is executed. Original implementation didn't work with forms.ps + because the CTM is changed with each page image. (4/29/89) + + 6: Flush stdout when postio is invoked with the -t option - just convenient + not necessary. (4/30/89) + + 7: Included a man page for the picture inclusion macros - file man/mpictures.5. + (5/6/89) + + 8: Added BoundingBox code to dpost - still needs to go in other translators. + Most of the work is done in common/bbox.c. (5/7/89) + + 9: Fiddled with the bracket building stuff in dpost.ps so things finally look + decent. Was particularly bad on the typesetter. + +10: dpost now generates a PageBoundingBox comment and ps_include.c accepts + the comment. Added -B option to enable/disable the BoundingBox calculations. + -Bon to enable and -Boff to disable. On by default now, but that may change. + Add similar code to the rest of the translators (6/20/89). + +11: Fixed ps_include.c so it properly handles %%BeginGlobal and %%EndGlobal. + Added braces and compare page.start to page.end instead of 0. + +12: Added xymove(hpos, vpos) for \X'PS ...' request - near the end of devcntrl(). + Must output position info for following PostScript. + +13: Added a call to endtext() immediately before the oput() call for \N'...' + requests. Without it spacing often messed up with -e2 but not -e0. + +------------------------ +Version 3.1 11/15/88 +------------------------ + + 1: postio can run as one or two processes (-R option) and can establish an + interactive connection with a postscript printer (-i option). Parsing of + status reports has been improved. The status query mechanism can be disabled + using the -q option. An exit status of 1 implies a system error (eg. can't + open the line) while 2 usually means there was an error in the PostScript + file. By default postio runs as a single process. The -B, -R, and -q options + can be used to speed things up some. A version of the program (previously + supplied in postio.tmp) that can help if you seem to be having flow control + problems can be obtained using the -S option. It's not generally recommended + and should only be used as a last resort! + + 2: Several widthshow encoding schemes have been added to dpost and can reduce + print time by 20% or more. The method used to encode lines of text can be + changed on the command line using the -e option. Level 0 produces output + essentially identical to previous versions of dpost. The default can be + changed by modifying the definition of ENCODING in ./Makefile. At present + only level 0 is thoroughly tested, although level 2 (ie. -e2) may be the + default and is undoubtedly worth a try. + + 3: dpost now supports color selection and reverse video. Access in troff is via + the stand-alone macro package ./macros/color. Examples are, + + .so /usr/lib/macros/color + .CL red "this prints in red" + .CL "white on black" "and this prints white text on a black background" + + The postscript procedures that handle color and reverse video can be found + in ./postscript/color.ps. Additional colors can be added to the colordict + dictionary defined in ./postscript/color.ps. + + 4: The dpost drawing routines have been improved and have been moved from the + prologue (ie. ./postscript/dpost.ps) to ./postscript/draw.ps. That file is + only included if needed. Drawing routines now support the ability to group + a series of drawing commands together as a single path. May be useful for + future versions of pic that wish to fill regions with colors or gray levels. + Access is via the new "x X BeginPath" and "x X DrawPath" device control + commands. In addition there's some complicated PostScript code in file + ./postscript/baseline.ps, that can be used to set text along an arbitrary + curve. It's terribly confusing and I doubt anyone will have the patience to + bother to figure it out. + + 5: A simple picture packing troff preprocessor (picpack) has been included and + the code needed to recover pictures and text has been added to dpost. The + program is designed to supplement to the original picture inclusion mechanism, + and should ONLY be used when absolutely necessary. Using dpost to pull picture + files into a document is strongly recommended and will always be the more + efficient and portable approach. picpack simply provides a way to combine + pictures and text in a single file before dpost is executed. It may help in + a distributed printing environment where the user runs everything through + troff while a spooling daemon (eg. lp) handles the postprocessing. There + are serious disadvantages to this approach, with perhaps the most important + being that troff output files (when picpack is used) will likely result in + files that can no longer be reliably passed through other important post- + processors like proof. + + 6: Code to handle host resident PostScript fonts in dpost has been tested and + finally works. The -H option points dpost to a host resident font directory, + which by default is NULL. Host resident font files stored in that directory + must be assigned a name that corresponds to the one or two character troff + font name. Width tables must also be built (see buildtables/README), the new + binary font files must be installed in /usr/lib/font/devpost, and a mapping + definition from troff's name to the PostScript font name must be added to + ./postscript/dpost.ps. + + 7: The default pattern length in postdmd has been reduced to from 10 to 6 bytes. + Printers with fast processors (eg. PS-810s) often benefit from a further + reduction, while optimal performance on slower printers (eg PS-800s) may + require larger pattern sizes. The pattern length can be set using the -b + option. Increasing the pattern size usually increases the size of the output + file. + + 8: Line drawing in posttek and postbgi includes code that automatically ties + lines to device space coordinates when you select a non-zero width. Helps + eliminate the variation in line thickness that many observed. The default + line width in posttek and postbgi is still 0 (which gets 1 pixel). If you + want a different default change the definition of variable linewidth in files + ./postscript/posttek.ps and ./postscript/postbgi.ps. + + 9: Defocused lines in posttek have been fixed. + +10: postbgi now supports color and can be used to translate most PRISM (color + BGI) jobs. Special device specific tuning needed for many PRISM jobs can be + enabled by using the -P"/prism true" option. Missing pieces (eg. subroutines) + needed for translating PRISM jobs, have also been implemented. + +11: postreverse can reverse the pages in documents that conform to Adobe's 1.0 + or 2.0 file structuring conventions, and it works with all the translators in + this package. The new version is backwards compatible, but files produced by + the new translators should not be passed through old versions of postreverse. + The likely result will be no output at all. If you choose to do a partial + installation put the new postreverse up first! + +12: All translators attempt to conform to Adobe's Version 2.0 file structuring + conventions. dpost output falls short, but only in the interest of efficiency. + Passing dpost output through postreverse (perhaps with the -r option) produces + a minimally conforming PostScript file. + +13: All the translators now support three options that pass arbitrary PostScript + through to the output file. The -P and -C options add a string and the + contents of a file respectively immediately after the prologue. It's assumed + whatever is added is legitimate PostScript - there is no checking. In each + case the added PostScript code becomes part of the job's global environment. + + The -R option can be used to request special action (eg. manualfeed) on a + global or page basis. The argument should be "request", "request:page", or + "request:page:file". If page is given as 0 or omitted the request applies + globally. If file is omitted the lookup is in /usr/lib/postscript/ps.requests. + The collection of recognized requests can be modified or extended by changing + /usr/lib/postscript/ps.requests. + +14: PostScript code (from Johnathan Shopiro) that produces bolder versions of the + Courier fonts has been included in file postscript/fatcourier.ps. The file + can be added to individual prologue files (eg. dpost.ps) or pulled in as + needed using the -C option. + +15: postmd is a new program that can be used to display a large matrix as a gray + scale image. May help if you're looking for patterns in a large matrix. A very + optimistic estimate suggests you can display up to a 600x600 matrix (with five + different shades of gray) on 300dpi printer using 8.5x11 inch paper. + +16: What's available in buildtables has been cleaned up and works well with the + new version of postio. It can be used to have PostScript printers build troff + width tables for both printer and host resident fonts. + +17: The PostScript bind operator has been applied to all procedures that are + expected to be executed more than once. Redefined save and restore procedures + are no longer needed and saverestore.ps is not included in this package. + +18: The bizarre PostScript code used to get to the upper left corner of a page + in old versions of dpost.ps and postprint.ps has been replaced by something + that's at least slightly more comprehensible. All prologues have also been + changed so picture inclusion (eg. including a pic picture that's been run + through troff and dpost) should work better than previous versions. Still + missing (from most translators) is the %%BoundingBox comment and even when + it's put out (by postdmd) only the dimensions are correct - sorry! + +19: The careless mistake in the DKHOST section of postio that some noticed belongs + to me (not Allan Buckwalter) and has now been fixed. + +20: By default all prologues still use the current clipping path to determine page + dimensions, but that behavior can be disabled by setting boolean useclippath + (in each prologue) to false. In that case the page dimensions will be taken + from array pagebbox, which by default is initialized to 8x11 inch paper. The + -P options (in each translator) can change useclippth and pagebbox. + +21: New in the misc directory is sample lp support from Maryann Csaszar and a + simple program that converts host resident font files obtained from a Macintosh + to a format that works on Unix. + |
