Released 6 Nov 2002

ExifExtractor.java

  • Proper traversing of Exif file structure and complete refactor & tidy of the codebase (a few unnoticed bugs removed)
  • Reads makernote data for 6 families of camera (5 makes)
  • Tags now stored in directories... use the IFD_* constants to refer to the image file directory you require (Exif, Interop, GPS and Makernote*) -- this avoids collisions where two tags share the same code
  • Correct extraction of multi-component values
  • No longer decodes image to extract Exif data -- this is much faster
  • Takes componentCount of unknown tags into account
  • Now understands GPS tags (thanks to Colin Briton for his help with this)
  • Returns null when no Exif data present, instead of throwing an exception
  • Some other bug fixes, pointed out by users around the world. Thanks!

ExifLoader.java

  • Removed (unnecessary)

ImageInfo.java

  • Stored IFD directories in separate tag-spaces
  • iterator() now returns an Iterator over a list of TagValue objects
  • More get*Description() methods to detail GPS tags, among others

TagValue.java

  • New class to encapsualte information about a particular tag

Rational.java

  • Improved toSimpleString() to factor more complex rational numbers into a simpler form. I.e. 10/15 -> 2/3
  • toSimpleString() now accepts a boolean flag, 'allowDecimals' which will display the rational number in decimal form if it fits within 5 digits. I.e. 3/4 -> 0.75 when allowDecimal == true

JpegSegmentReader.java

  • New class to extract APP1 segment (and others) from a Jpeg file -- this avoids decoding images just to get metadata

tests\*.java

  • First collection of basic unit tests, to compile against JUnit
  • Doesn't yet cover all classes

Website

  • A collection of JPEGs from various digital camera models, collected on the web and contributed by many users of ExifExtractor
  • Updated documentation
