How can I apply CSS to a JPG server-side?
I have JPGs that I want to run a couple CSS operations on server-side, for instance, crop and round corners, then served these processed JPGs to clients. The clients can't interpret CSS, they can only render JPGs.
Is there a tool that can do this, maybe some sort of commandline web browser?
Edit: I really want this to be CSS, there are other tools for processing images but CSS is what I'm looking for.
This can be done using wkhtmltoimage
Install wkhtmltoimage
Create an html document with a link to your image and the various css in it. cake_corners.html:
<img src="cake.jpg" style="-webkit-border-radius: 50px;">Run wkhtmltoimage. You might need to use a "crop width" flag.
% ./wkhtmltoimage --crop-w 660 --format jpg cake_corners.html cake_corners.jpg
The output will be your image with the styles applied to it. You'll probably need to play with it a bit.
