- So you've never used Calligrapher then :-)
-
- Calligrapher is an ST wysiwyg word processor, which, I am told, drivers
- LaserJets fairly well. Unfortunately, the PostScript driver is terrible.
-
- A few examples (some are bugs, some are just bad PostScript):
-
- 1. If using a font that is not built in to your printer, the driver does not
- download a definition for the font, then refer to that definition to paint
- characters. Instead, it explicity draws the outline of each and every
- character, fills it, draws the outline again, then strokes this. Thus
- each character in the output takes, typically, 4 Kbytes of PostScript.
-
- 2. The coordinates for the lines used to draw the character outlines
- are frequently out by 2 points or so, making the characters look like
- they're printed on a 60dpi printer, not 300, 1200 etc.
-
- 3. It will not draw any characters not in the Level 1 Standard Text
- Encoding. When asked to print a copyright symbol, it printed a plain c.
- When I complained, the authors (Working Title) sent a new driver that
- still put out a standard letter c, but then drew a thick polylined-circle
- around it. This looks really messy (the circle is much to heavy compared
- with any of the fonts used for the c character). Working Title flatly
- refused to amend their driver to either use the (c) character from
- a Level 2 coding vector, or to output the (c) from the Symbols font.
-
- 4. Rounded boxes are drawn with the wrong radii for the corners, so
- the corners do not join properly with the straight edges.
-
- 5. A good number of the symbols are mapped incorrectly, so what appears
- on the screen as an apostrophe comes out on the printer as a cent.
-
- 6. The GEM fill patterns are rendered VERY inaccurately; anyone who has
- access to both Calligrapher and TimeWorks Publisher 2 will find it
- interesting to compare the output. The
-
- 7. It does not generate *any* DSC directives.
-
- 8. Every character is positioned independently. (For example, 'abc'
- would appear as something like (a) x y moveto show (b) x y moveto ...
- instead of (abc) x y moveto show. Apart from generating larger
- PS files, it exposes Calligrapher's errors in character positioning,
- and they are not always spaced out correctly. By using the (abc) form,
- any spacing errors would be inter-word only. (Obviously, it would
- be better if it got all the character positions correct in the first place).
-
- 9. And zillions of other bugs, inefficiencies and wierdos that I won't
- waste further space and time on for now...
