Optimizing Accuracy

To obtain an optimized accuracy and a correct position of the text inside the picture, you need to store your screen dimensions (in millimeters), in the following two variables: 

  • set CATWidthMMOfScreen = width_in_millimeters
    (on Windows)

    or

    export CATWidthMMOfScreen = width_in_millimeters
    (on UNIX)
  • set CATHeightMMOfScreen = height_in_millimeters
    (on Windows)

    or

    export CATHeightMMOfScreen = height_in_millimeters
    (on UNIX)

Otherwise, the measured dimensions may vary depending on the operating system.

You have to do these measurements by yourself using a tape measure. The screen dimensions correspond to the horizontal measurement followed by the vertical measurement.

If your computer does not use the full screen for display (e.g. if there is a strip on the left side and right side of your screen), you have to measure only the part of the screen used for display.
