Terry,

I have been using your QR Code with success. Very nice!

Optionally, I would like to draw a border. Here is my latest set of parameters:
(showborder borderwidth=2 borderleft=5 borderright=5 bordertop=5 borderbottom=8 color=ff0000 backgroundcolor=ffff00)

The colors do work. But I cannot get a border. I tried different parameter combination to no avail. Am I missing something?

Could it be that a border is not allowed for QRCodes?

Is it the same issue for includetext?

As a test, I tried to use the height parameter: It worked but, as expected, created a distorted QRCode. It seems that a QRCode dimension is computed based on the data and the correction level. So, it seems that the height and width parameters should not be allowed.

Is there a way to know what parameters are acceptable or not for a given symbology?

And last, I saw some QRCodes with an image (logo) in the middle. Do they work? Can we do this?

Again, thank you for your dedication!

-Chris

Hi Chris,

the border-related parameters worked only for 1D barcodes (renlinear)
if you need border, caption, scaling, you'll need to write some postscript
code

the image/logo inside QRCodes are treated as "defects" (ie. error bits) by
the decoders.
if the "error bits" are within the allowable errors (errorlevels), they can
be decoded without any problems. BWIPP does not support image-embedding so
you have to mix them with image manipulation softwares.
