The cropping of an image is defined by 3 values

- X : Means the horizontal position from left border
  Example : If X=25% then the first quarter from left is left.
  This position can be shown in percent of total image's width or in pixel. This depend of the setting define in the configuration dialog box
- Y : Means the verticla position from top border of original image
  Example : If Y=25% then the first top quarter of original image is left
  This position can be shown in percent of total image's height or in pixel. This depend of the setting define in the configuration dialog box
- Zoom : Means the part of the image which is kept
  Example : If Zoom=33%, then the cropping image will be 1/3 size of original image.
  This value can be shown in percent of total image's size or in pixel. This depend of the setting define in the configuration dialog box
