Are you using FOP in your Desktop app (meaning you feed and FO file and
output one of the supported formats) or you just want to use some
classes to get the list of fonts in your system?

Hi,
I'm making a call to
org.apache.fop.tools.fontlist.FontListGenerator.listFonts( ... ) to
get a list of font names for my desktop application. To get the font
names, I take the keys from the returned fontFamilies SortedMap; the
actual data is junked.
I hadn't realised just how much memory is used by listfont( ... ) - on
some platforms such as Windows 7, in excess of 250 MB. In this case
I'm hitting out of memory errors.
I was wondering if there's a simpler way (uses less memory) to get
just the font names (first family names)? As I said, I don't make use
of the metrics and other font details...just the first family name for
each font. Digging down into listfont( ... ), I was wondering if it's
safe to take the firstFamilyName and place it into a list say and then
drop the following lines for the containers/sort?
Iterator iter = fontInfo.getFontTriplets().entrySet().iterator();
while (iter.hasNext()) {
Map.Entry entry = (Map.Entry)iter.next();
FontTriplet triplet = (FontTriplet)entry.getKey();
String key = (String)entry.getValue();
FontSpec container;
if (keyBag.contains(key)) {
keyBag.remove(key);
FontMetrics metrics = (FontMetrics)fonts.get(key);
container = new FontSpec(key, metrics);
container.addFamilyNames(metrics.getFamilyNames());
keys.put(key, container);
String firstFamilyName = (String)container.getFamilyNames().first();
List containers = (List)fontFamilies.get(firstFamilyName);
if (containers == null) {
containers = new java.util.ArrayList();
fontFamilies.put(firstFamilyName, containers);
}
containers.add(container);
Collections.sort(containers);
} else {
container = (FontSpec)keys.get(key);
}
container.addTriplet(triplet);
}
I'm guessing a lot of memory is chewed up in the containers/sort
section...but really I can't be sure as I don't fully follow what's
going on!
Ideally I'd just up the amount of memory supplied to the desktop
application, but I don't have that option and besides, it just delays
the problem of running out of memory.
Thanks in advance,
Bernard.
