Could you run ICEpdf with "FINEST" level logging enabled to help us diagnose this issue. More information on enabling logging on ICEpdf can be found here, http://www.icesoft.org/wiki/display/PDF/Logging .

As i told to you before . the icepdf works fine in all the Systems less the ubuntu. 12.04.
¿Is IcePdf use any ressources of the OS system to convert to image(Fonts,codification,etc...)?

Please , we need to get the solution for this problem.

Thank you in advance

The issue is related to how font substitution can very from system to system. The following code will force ICEpdf to store the found system fonts in ~./icesoft/icepdf/ folder.

// read/store the font cache.
ResourceBundle messageBundle = ResourceBundle.getBundle(
PropertiesManager.DEFAULT_MESSAGE_BUNDLE);
PropertiesManager properties = new PropertiesManager(System.getProperties(),
ResourceBundle.getBundle(PropertiesManager.DEFAULT_MESSAGE_BUNDLE));
new FontPropertiesManager(properties, System.getProperties(), messageBundle);

The fonts in this file will be retrieved for future lookup when font substitution is needed. If you look carefully at the logs as described in the wiki above you maybe be able to comment out the particular font that is causing the layout issue.

This appears to be rendering correctly in 5.0.5 both OS and PRO releases. Work was done around a width issue which likely also effected this document.
