Craig Drummond is porting his graphical font installer, kfontinst, to KDE's control panel. Previously, the program was a stand-alone designed for use in the KDE desktop environment, but Drummond plans to make it a tightly integrated function that has the potential to be distributed right along with the rest of the KDE modules. Drummond has set up a website to display project progress and screenshots at www.cpdrummond.uklinux.net/kfontinst-new/. One of the improvements to the new version of kfontinst he promises is the ability to configure X11, Ghostscript, and Star Office for truetype and type 1 fonts, and to preview fonts.
kfontinst isn't the only graphical font previewer and installer that's been developed for X, but it appears to be one of only a handful. A project called gGlyph is listed at filewatcher.org, but appears to have been neglected since about a year ago. Another, called gfontview, previews fonts but doesn't install them. Drummond is soliciting comments and suggestions for improvements to kfontinst. He can be contacted at email@example.com.
