WordPerfect® 5.1 for DOS

Problem

Symptoms: How does WordPerfect select fonts for CGM files that are converted either through retrieval or through GRAPHCNV? How does WordPerfect handle fonts in the different graphic formats (e.g., what is the difference between CGM, HPGL, or PCX fonts)? Solutions: Fonts basically are only an issue with vector graphic files since with bit- mapped images, the text is just a series of dots included as part of the graphic.

With the HPGL format, WP will usually use a Times Roman font set (the WP graphical font). This font can be very displeasing as it will be monospaced and can look like a stick font. The HPGL format will give a very specific way of drawing a character. WP just converts that to a Times font and draws it differently.

CGM fonts are handled much differently. The font list for the graphic file in this format is found at the very beginning of the file. WP looks for a Font code or font identifier (such as TR or TimesR for Times Roman, Helv or HLV for Helvetica, etc.). WP will look for the Times Roman, Helvetica, or Courier fonts that are created graphically, then try to match from there. This can be very difficult to match sometimes.

If a user copies the WP.DRS file from DrawPerfect to the WP directory, it will not result in the fonts coming in any better. The conversion routine in WP is what determines the nature of the fonts, and it only looks to the Helvetica, Times Roman, and Courier graphical fonts. DrawPerfect, on the other hand, will match the fonts correctly almost every time because its conversion routine is much better.
