Title: Paperwallet with Rorschach QR Code Post by: gdsl on February 12, 2013, 01:47:51 PM I wanted to make some paper wallets but found the image resolution on https://www.bitaddress.org wanting...
I've made a php script that creates an addess with the vanity genrator and composes a high resolution wallet png file. This can be done offline as long as the pc has PHP installed. When using the DOCTOR 75R_/PSY template the QR Code looked ugly and oldfashioned so I added a "Rorschach" filter. A demo wallet is available at http://zen.gdsl.no/bitcoin/wallet-14ceber67effwcmazawxfhquu7ug4d8e6o.png.html?sizes=1 (http://zen.gdsl.no/bitcoin/wallet-14ceber67effwcmazawxfhquu7ug4d8e6o.png.html?sizes=1) The CR Code is generated with "High" error correction, so, in theory, it should still be readable with 30% data loss. I would highly apreciate if someone could test the quality of the QR Code. Full source will be made public once QR Code quality is confirmed.

When using the DOCTOR 75R_/PSY template the QR Code looked ugly and oldfashioned so I added a "Rorschach" filter. Take a look at libqrencode by Kentaro Fukuchi. It's on github. The code is easy to understand and modify. It would be simple to add an option for rounded corners on modules, for example, or even to make modules some other shape altogether than squares. See the file qrenc.c in the source code. |
