Description

330: int photometricType =
(int)dir.getFieldAsLong(TIFFImageDecoder.TIFF_PHOTOMETRIC_INTERPRETATION);

Image has no field with tag "TIFFImageDecoder.TIFF_PHOTOMETRIC_INTERPRETATION".

I use next workaround:

int photometricType;

TIFFField photometricTypeField =
dir.getField(TIFFImageDecoder.TIFF_PHOTOMETRIC_INTERPRETATION);

// Get the photometric interpretation.
if (photometricTypeField == null)
photometricType = 0; // White is zero
else
photometricType = photometricTypeField.getAsInt(0);
