Hi Robin,
Excellent thread.
In an implementation using the QR code plugin, I’ve need to generate large QR Code images, so that my client can easily include the codes in their printed materials.
WHAT I FOUND
There's a maximum allowed value for the “size” parameter of 547 pixels. According to Google, anything over that would exceed their generator’s 300,000 pixel maximum size design parameter. (548 x 548 = 300,304)
http://code.google.com/apis/chart/image/docs/chart_params.htmlA 547 px image allows for a 2.75" x 2.75", high resolution print to be created directly from the image. 200 ppi is pretty much the minimum resolution required for quality printing without too many jaggies, so this size is usually adequate for most print applications.
THE CHALLENGE
A 547 x 547 pixel image is a bit large for display as a thumbnail on a list page of QR Codes and corresponding titles/URLs.
WHAT’S NEEDED
Does anyone know a way to generate thumbnails of the larger generated QR codes that when clicked would display the full sized image for copying and download, similar to the way CMSB thumbnails work.
Thanks,
