Filter window

In this window, you can set the font selector to show only the fonts which satisfy some criteria. You can specify values for font foundry (vendor), weight, character set, slant, set width, and spacing (see the section called Font attributes in X Window System and XLFD for description of these and other font parameters). You can choose *, which means "any value"; you can also specify several values for the same field: just click on several of the them with the left mouse button (you do not need to hold SHIFT or CTRL).

You can also specify allowed font types, using checkbuttons at the top of this window. Possible types are bitmap fonts, scalable fonts, and scaled bitmaps. The most common fonts are bitmap fonts; scalable fonts (TrueType and Type 1 PostScript) usually produce equally good quality, but not all implementations of X Window System are able to use them.

As the name shows, scalable fonts can be scaled to any size without loss of quality. While it is possible to scale bitmap fonts as well, the quality of scaled bitmap fonts is disastrous. For this reason, by default font selector does not show scaled bitmap fonts.

After you have set your filter, you can return to the main window (do not press OK or Apply — just choose the tab Font), which will now only show the fonts satisfying your criteria. To remind you about this, the main window will now show words Filter applied.

To return to the default filter (i.e., show all possible fonts except for scaled bitmaps), press Reset Filter either in the Filter window or in the main window.
