This package contains a sample Python script to automate manual cropping of the image with the TL toolkit. To avoid confusion, we'll refer to this as the tl_cropping_Python script throughout the documentation.
tl_cropping_Python provides a python script that can be executed within the Matrox Imaging Library. This script can be used to quickly and automatically crop an image to a predefined rectangle. If the file doesn't already exist, the script will automatically create a new file and continue. The script can be run from the command line using the Python interactive interpreter or can be included in your existing Matrox Imaging Library Python scripts.
tl_cropping_Python was developed based on customer requests to automate the manual image cropping operation. Often users wish to crop an image to a certain boundary without having to first identify it in the image.
The following sequence of steps demonstrates how to crop an image.
This example will use the 1280 x 720 resolution image stored in the HARDCOPY2 folder. We'll crop a 48x48 square centered around the upper left hand corner.
Launch the Python interactive interpreter.
