I would like to check if a qr code like this:
on the screen of the pixl can be read without a problem, but I don't have any pixl yet...
Can someone try this please?
You are pushing the envelope... the pixels are so small that the smallest 'visual impurity' - such as a scratch or a small lint - in the line of sight between display and reading optics and a not perfect view angle - creating reflections / blurs - stresses error correction. Last but not least contrast is an issue as well.
The wikipedia says it's got lots of error correction pixels :-P
Resampled to 57x57 pixels:
It works fine on the screen of my Mac, in a 128*64 rectangle that has 5.4cm diagonally:
Can someone try this please, please? :-)
I'm not near a Pixl at the moment, but anyone who wants to try this can use http://www.espruino.com/Image+Converter
Even if that doesn't work, a smaller QR code containing less data (<=32 pixels so you can double it up) would be fine I'm sure.
Just tested - works great! Just ensure that when you import the image, black pixels really are black.
The image converter above defaults to using white as a 1, but on a Pixl a 1 is black. You just have to tick the invert checkbox.
Just tested as well. It seems to work like a charm.
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
