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

Status in Sikuli:
  Fix Committed

Bug description:
  ***** workaround

  use Pattern.similar(0.99)

  --------------------------------------

  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.
