Subject [jira] Commented: (PDFBOX-429) PDFontDescriptorDictionary methods returning negative height values
Date Wed, 18 Feb 2009 21:16:01 GMT

    [ https://issues.apache.org/jira/browse/PDFBOX-429?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12674782#action_12674782

Brian Carrier commented on PDFBOX-429:
--------------------------------------

Initial patch by Ken Glidden applied that returns the absolute value of the negative number.
We were not able to trace down the source of the bug, but this fix seems to give correct numbers.
 

Sending        PDFontDescriptorDictionary.java
Transmitting file data .
Committed revision 745653.

Since we aren't sure if it is actually the correct fix, I will leave this open.

> With the attached file, PDFontDescriptorDictionary.getXHeight() and PDFontDescriptorDictionary.getCapHeight()
will return a negative value from the "dic.getFloat(...)" function. These height values should
never be less than 0.
