Problem with Asian language fonts

[Sourabh Patwardhan]

Hi,   I am using FOP 0.20.5 to generate PDF documents on the fly in my web application I get an OutOfMemoryError when I try to generate PDFs with Asian language fonts   I found out that this is due to embedding the font in the PDF It seems that for every rendering of the PDF, the FOP driver loads the entire font file in memory (I am using some custom third-party fonts which have approx 30 MB TTF files)   When there are concurrent requests for PDF generation in my web app, the memory demand surges and causes OutOfMemoryError It seems that the memory allocated for the TTF file is not released as soon as the rendering is complete Increasing JVM heap size does help..but only upto a certain extent   I tried removing the "embed-file" option from the config file and the memory problem does not occur However, Adobe Acrobat 6 does not seem to find the custom font even when it is installed on my Windows system The custom font is not from the Asian Font Pack from Adobe; it is a Monotype Sans font from Agfa   I have two questions: 1. Is it possible to prevent loading of the TTF file into memory every time a PDF is rendered? (by doing some sort of caching) 2. Is it possible (through any public FOP API) to pass the TTF file only once to FOP, so that it is cached in memory?   Any alternative solution / suggestion is welcome!     Thanks and regards, Sourabh Patwardhan
