Fonts for Text Output

Hardware (bitmap) fonts are now used, which means faster solid text, but the choice of sizes are limited and slight differences may occur between the screen font and the hard-copy font60.

If available the ``Times-Roman'' font family is used. Depending on the size of the window and the required size of characters, the nearest font size will be used. However, very big and very small fonts are not available in X-11 so the range of sizes is limited. If the required font is not found, a standard X-11 font will be used instead (6x10 or 9X15), but this font will be far from the ideal size. It has been seen that some X-servers have fonts with different aspect ratios to those for which FIT2D was designed. This may lead to text extending outside the normal region. For PostScript output the exact font size (as originally requested) is produced, so slight differences in the size of characters on the screen and on paper will occur.

X-11 (generally) does not provide for rotated characters (although PostScript does), so rotated text is simulated. In the future other fonts e.g. Greek characters, may be provided.
