out of memory exception while creating font metrics
Hi all,
To use system fonts in FOP, I am creating metrics files for each
font. While doing this process, my program is giving out of memory
exception.
How to resolve this problem...
I am attaching the method what I have written..
Please suggest me in this regard, if anybody already faced this
problem...
Thanks & Regards,
Chandrasekhar Sanku.

The metrics generator holds the whole font file in memory
and creates a substantial amount of additional in-memory
structures. There is a reason why you get an OutOfMemory
error, you see... Unless someone converts the program to
use java.io.RandomAccessFile instead of TTFFile, you'll
need to run the JVM with more memory than the default for
processing fairly large fonts.

I'm not sure what you mean by "I can't specify the /*embed-file
attribute*/" I have no problem using embed-file="no" in the font
declaration. Unfortunately, the rendered PDF will only display
text in Acrobat Reader if the font in question has been installed
with Acrobat, because FOP doesn't provide a mapping in the PDF
font dictionary which Acrobat can use to get the system's font
file.

Thank you very much...
Actually my problem is that, I can't specify the embed-file attribute value in the userconfig.xml file.
Hance, is there any workarround to achieve the linking font issue...?
Bye

It doesn't work with 0.20.5, because of problems with font name
mangling. You *must* embed non-standard fonts.

Problem with Linking Font (Not Embeded Font)
Posted by Varadharajan Sethuraman <va...@yahoo.com>.
Hi All,
I have a problem with linking the font (not embeded font) with pdf.
In the userconfig.xml file I have specified only metric-file attribute. I haven't specified
embed-file attribute value.
Following highlighted paragraph from taken from http://xml.apache.org/fop/fonts.html
It says that particular font file should be there in the local system. Yes, Its there. But eventhough it is not working...
The "kerning" and "embed-file" attributes are optional. Kerning is currently not used at all. If embedding is off, the output will position the text correctly (from the metrics file), but it will not be displayed or printed correctly unless the viewer has the applicable font available to their local system.
If any one knows about Linking font with pdf using FOP.
Kindly help me....
Regards
Varadharajan S

Hi Chris,
I did the same. If I increase the heap size, I am not getting any
error.. But if I run the program, without increasing the heap, then it's
giving the problem. Can't we run the program without increasing the heap
size?????
Is there any alternative to this problem other than this.
That's my basic doubt.....
Thanks & Regards,
Chandrasekhar Sanku

Some of the fonts in the Windows System area are fairly chunky, Arial
Unicode
has loads of glyphs in it, and 64M probably isnt enough to process it.
Increase your JVM heap to 256M, and try again. If it still fails, do a
System.out on each font/style to show progress so you can see which font
causes the OutOfMemoryException.
