Adding a logo to QR Code using ImageMagick
I'm trying to add a logo to a QR Code image. Logo image area must be lower than 12% of the QR code area, in order to be easily used by the consumers.
The problem is that the output file must be in EPS format. So it means that I can't play with it in ImageMagick. I'm well aware of the fact that working with vector graphics is complex. I have the logo and the QR code in EPS format. In order to create that "safe margin", I created a canvas 10% larger than logo, composited canvas and logo into a padded logo, resized the new file (via -density option) to 12% of the original QR code area and composited them.
The result was disappointing: No scanner could scan it.
The result I tried resizing the canvas to 10% of image area, still no good.
Keep that in mind that the QR is going to be carved on a physical plate, that's why I need vector output.

When trying to embed an image in a QR code, try not to cut off any “blocks”. Also, you can always add more redundancy to the QR code.

That's exactly my problem: how to not to cut off any "blocks"?

You’ll have to improve the positioning of the embedded image...? It can’t be that hard. You could always use a GUI vector graphics editor.
