'**SUMMARY**
This function allows us to translate a set of points from the crop window back to the coordinate of the source window.
**PARAMETERS**
* *ListofPts* - set of points from cropped image.
**RETURNS**
Returns a list of coordinates in the source image.
**EXAMPLE**
>> img = Image(\'lenna\')
>> croppedImg = img.crop(10,20,250,500)
>> sourcePts = croppedImg.uncrop([(2,3),(56,23),(24,87)])'

def uncrop(self, ListofPts):

    return [((i[0] + self._uncroppedX), (i[1] + self._uncroppedY)) for i in ListofPts]
