Subject EXIF on Jpeg brings Out Of Memory
Date Tue, 10 Jun 2008 13:42:57 GMT
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);

Gives me an out of memor exception, after a second. My image ist just 150 kb
big.
Unfortunatly there is no JPEGConstants.EXIF_TAG_ORIENTATION or similar.
Any ideas why that happens?

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