how to use xnview for make qrcode about scrolltext-esp8266

[DIYDave]

Hi fixduino,
First you need a jpg or bmp picture with the exact pixel. e.g. 64x64 or 128x64. (Crop / cut / reduce the picture in xnview) Then you must convert it to black&white (1bit) in xnview. (menu "picture"). After that, you save it in xbm-format. I can not say more, because it worked for me. If it does not work, you can send a test picture here.
Good luck and fun.
