returns null
NullPointerException in org.apache.pdfbox.pdmodel.graphics.PDShading.toString, when getDomain() returns null
------------------------------------------------------------------------------------------------------------
Key: PDFBOX-1013
URL: https://issues.apache.org/jira/browse/PDFBOX-1013
Project: PDFBox
Issue Type: Bug
Components: PDModel
Affects Versions: 1.5.0
Environment: Windows 7, and Ubuntu 8.04
PDFBox 1.5.0
Reporter: Craig Stires
Priority: Minor
Fix For: 1.6.0
The problem is that the toString method is called on objects which may have been returned as null
The suggested fix to this, in the attached patch is to check if null, then write an empty string
String s = "Shading " + shadingname + "\n"
+ "\tShadingType: " + getShadingType() + "\n"
+ "\tColorSpace: " + sColorSpace + "\n"
+ "\tAntiAlias: " + getAntiAlias() + "\n"
+ "\tCoords: " + (getCoords() != null ? getCoords().toString() : "") + "\n"
+ "\tDomain: " + (getDomain() != null ? getDomain().toString() : "") + "\n"
+ "\tFunction: " + sFunction + "\n"
+ "\tExtend: " + (getExtend() != null ? getExtend().toString() : "") + "\n"
+ "\tRaw Value:\n" +

[jira] [Resolved] (PDFBOX-1013) NullPointerException in
org.apache.pdfbox.pdmodel.graphics.PDShading.toString, when getDomain()
returns null
Posted by "Andreas Lehmkühler (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/PDFBOX-1013?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andreas Lehmkühler resolved PDFBOX-1013.
----------------------------------------
Resolution: Fixed
Fix Version/s: 1.6.0
Assignee: Andreas Lehmkühler
I introduced default values for the domain and the extend attributes, so that they can't be null. I also added a fix to avoid a NPE for the coords attribute as it can be null as proposed by Craig Stires.
Both was added in revision 1133328.
Thanks for the contribution!
