"python" PIL Bulk Draw picture Rectangle box Tool

Tools using Pil:python Imaging library, image processing Standard Libraries. The PIL feature is very powerful, but the API is very easy to use.

Installing PIL

Install directly via apt under Debian/ubuntu Linux

$ sudoapt-get installpython-imaging

Windows platform installs directly from PIP

pip installpillow

Bulk Tool Scripts

default execution is:                 Execute script command python drawline.py            1. Gets the ' png ' ' jpg ' file          2. draw a rectangular box with a width-to-height ratio of 0.5,0.5          3. Save the picture to the line folder under the current path
