Gary Lucas updated IMAGING-364:
-------------------------------
Description:
When calling TiffDirectory.getTiffImage(), Commons Imaging throws a null
pointer exception.
{code:java}
java.lang.NullPointerException
at
org.apache.commons.imaging.formats.tiff.TiffImageParser.checkForSubImage(TiffImageParser.java:78)
at
org.apache.commons.imaging.formats.tiff.TiffImageParser.getBufferedImage(TiffImageParser.java:261)
at
org.apache.commons.imaging.formats.tiff.TiffDirectory.getTiffImage(TiffDirectory.java:776){code}
If you call the alternate method
TiffDirectory.getTiffImage(TiffImagingParameters), it works okay. The problem
is that the internal method TiffImageParser().getBufferedImage() cannot handle
a null reference.
Here's the problematic code from TiffDirectory.java
{code:java}
public BufferedImage getTiffImage() throws ImagingException, IOException {
if (null == abstractTiffImageData) {
return null;
}
return new TiffImageParser().getBufferedImage(
this, headerByteOrder, null);
}
{code}
We could either make TiffImageParser more robust, or we could avoid passing in
a null value for the third argument.
{code:java}
TiffImagingParameters defaultParameters = new TiffImagingParameters();
return new TiffImageParser().getBufferedImage(
this, headerByteOrder, defaultParameters);{code}
