Example 20 with FileImageInputStream

use of javax.imageio.stream.FileImageInputStream in project imageio-ext by geosolutions-it.

the class TIFFMetadataTest method testImageRead.

/**
 * This test class is used for testing the capability of the TIFFImageReader
 * class to read EXIF metadata. TIFFImageReader class presented a bug when
 * the EXIF IFD pointer tag type was not LONG (type = 4) but was the new
 * IFD_POINTER type (type = 13) defined in the Technical Note 1 of the TIFF
 * Specification Supplement documentation. This variation provoked a
 * ClassCastException when the reader tried to cast the EXIF IFD pointer
 * data to the TIFFIFD class. This bug has been fixed by adding the
 * possibility to contain the IFD_POINTER type to the EXIF IFD pointer tag.
 * The testImageRead() method reads an image with the new TIFF tag type and
 * checks if the EXIF tags has been read by the TIFFImageReader.
 *
 * @throws IOException
