Re: EXIF on Jpeg brings Out Of Memory

[Craig L Russell]

If possible, can you create a JIRA issue and attach the failing file?

https://issues.apache.org/jira/browse/SANSELAN

Thanks,

Craig

Hi all,

i want to use Sanselan for extracting EXIF information.
This code:

 IImageMetadata metadata = Sanselan.getMetadata(jpegFile);
 JpegImageMetadata jpgmd = (JpegImageMetadata)metadata;
 TiffField field =
jpgmd.findEXIFValue(TiffConstants.EXIF_TAG_ORIENTATION);


big.

Any ideas why that happens?

And a second question: how is the state of writing EXIF tags to jpeg?
Thanks in advance
Chris.
