** Summary changed:

- pattern.exact() fails even when a perfect match exists
+ X-1.0rc3: pattern.exact() fails even when a perfect match exists --- workaround

  I am currently using the java Sikuli to verify generated images on the
  screen, and I need to verify that they are a 100% match (for regression
  testing). I was using the following code the verify:
  
  Pattern exactMatch = new pattern(pathToMasterImage).exact();
  boolean result = screen.exists(exactMatch, someTimeout) != null;
  
  however, on some images, this would fail. I captured screenshots on the
  failure and compare the pixels and they were an exact match. I also
  called a search for the same image immediately after using .similar()
  and gave it a minimum of a 0% match, which returned a match object with
  a score of 1.0, so there did exist a 100% match on the screen, but the
  search for the pattern with a .exact() setting seemed to still fail.
  
  Currently running the java portion of sikuli Sikuli-X-1.0rc3 (r905) 32
  bit on a win64 system (running 32bit java though) and windows7. Repro
  for this bug is difficult, but I ran it over a series of images, and
  roughly 1 in 6 seemed to fail, albeit it was different images that
  failed (on the same set of images) every time I ran it.
