Image Manipulation with Python

So an e-Ccommerce project I’m working with has hit a new requirement to create bulk vouchers images for clients that can be sent out using social media.

We set out to create a template and fill it out with a loop.

I chose Python3 for the task. There are lots of libraries like Image Magic that have overlay systems. But this is done in Raster so the image will get re-compressed.

Then it hit me that SVG is really just an XML spec. And a great idea emerged.

• Add template tags like in a text box in an SVG file.
• Do a plain find and replace on the file.
• Convert to PNG with ChairoSVG

Wrap up

I ended up with a script that reads a template file and inserts fields from an Excel sheet. This can be extended further to run from within a PHP front end. But it works nicely as is.
