[jira] Commented: (PDFBOX-634) CFF parsing failure

["Villu Ruusmann (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-634?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12837275#action_12837275 ] 

Villu Ruusmann commented on PDFBOX-634:
---------------------------------------

The least we could do is to provide a fall-back mechanism to PDFBox 0.8.0 level of functionality.

CFF font parsing occurs in org.apache.pdfbox.pdmodel.font.PDType1CFont#ensureLoaded(). I guess it would be wise to invoke this method right in the constructor at take immediate action in class org.org.apache.pdfbox.pdmodel.font.PDFontFactory if an exception is thrown, and not to postpone it to the point (ie. methods #encode, #getFontWidth, #getFontHeight) where there is no easy way out.
