Text bluring

The OCR mechanism and text pattern searching is implemented in pure java to work 100% efficient. However, because no heuristic is used, these mechanisms are not ready for any noices nor text bluring. Unfortunately some operating systems (like Microsoft Windows) do use text blooring in order (in theory) to improve quality of text presentation. In some operating systems (like Microsoft Windows Vista and newers) text blooring is by default turned on. Microsoft calls the bluring option 'ClearType'. While creating the projects, you should take care abour blooring because of two reasons:
  1. text blooring makes OCR or text pattern searching not working,
  2. the image patterns defined on computer with 'cleartype' turned on may be not found on the computer, where this option is turned off (and vice verse) or has other settings of this functionality.
That is why it is strongly recommended to turn the 'Cleartype' off, or take the special care, it turning off is not possible.
