Constructor Detail

JFontConfigurationDialog

public JFontConfigurationDialog(java.awt.Frame frame)

dialog window to select the mapping from FIG font index to one of the available TrueType fonts.

This dialog window can be used to select the mapping from FIG font numbers to actual TrueType fonts.

Background and Motivation

The default mapping from font index to TrueType fonts in jfig still uses the three fonts ("times", "helvetica" "courier") guaranteed to be available on all Java2 platforms. Unfortunately, current JDKs use their own TrueType fonts from the Lucida font family, whose font metrics differ radically from the Postscript fonts expected by the FIG format. This often leads to annoying effects, like fonts protruding beyond boxes, etc.

However, modern JDKs (version 1.3+) are able to load other TrueType fonts installed on the target workstation, which might include the fonts expected by the FIG format or at least several of the readily available substitutes. Most of these fonts have FontMetrics which are much more compatible with the FIG/xfig values.

Using extra fonts in jfig requires adding a font mapping description to the jfig configuration files, e.g. jfig.gui.FontCache.Bookman-LightItalic ItcBookman Light,italic This dialog window lists all TrueType fonts found on your system and lets you select the mapping for each of the 35 Postscript fonts defined in the FIG file format.

NOTE: The TeX/LaTeX fonts are currently not supported by jfig.

Method Detail

createRenderingHints

public void createRenderingHints()

loadFontIconImages

public void loadFontIconImages()

(re)create our image array, one 220x20 pixel image per font. This method loads the "/jfig/images/fontmenu.gif" resource image(s).

listAllFonts

public void listAllFonts()

buildGUI

public void buildGUI()

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent evt)

Specified by:

actionPerformed in interface java.awt.event.ActionListener

getFoxScaleFactor

public float getFoxScaleFactor(int fontIndex)

calculate an estimated "string width" factor from the Java Font currently selected for FIG font index i, and the actual measured values from a FIG printout, both at 12pt size. The data relies on a single sample string (quick brown fox) and is only a coarse estimate.

getFoxScaleFactor1

public float getFoxScaleFactor1(int fontIndex)

doApplySelectedMapping

public void doApplySelectedMapping()

retrieve the currently selected font mapping and apply to FontCache. You should probably save the jfig properties to make your changes persistent...

doInitializeFontMappingFromFontCache

public void doInitializeFontMappingFromFontCache()

msg

public static void msg(java.lang.String s)

usage

public static void usage()

public static void main(java.lang.String[] argv)
