[03:18:25] <Gaddel> but i get IOError: encoder png not available

[18:26:02] <jazwec> Hello guys.. Im still struggling a little bit with drawing this: http://www.fi.muni.cz/~xdrabek1/ib111/sachovnice.png ..I now have a function which drawes me chessboard and i have one that draws a circle in the middle. but i dont know how to make more circles in waves..

[18:26:25] <jazwec> my code looks like this: http://bpaste.net/show/47d1VRAFG8Q35AfvaBnw/

[20:59:25] <gp5st> how can i add a QR code into an image? I was using https://pypi.python.org/pypi/qrcode/4.0.4 to generate the qrcode, but I can't figure out how to insert it into an image at a certain spot.

[21:28:30] <jazwec> please, if anybody could take a look at my code and help i would be very thankful: http://bpaste.net/show/1FBCRZfNetMmwk9seZJa/ im experiencing two problems. first function should give me this output: http://www.fi.muni.cz/~xdrabek1/ib111/sachovnice.png but i can only make one circle in the middle, not more of them... and second two functions are for hiding a bitmap to other picture and then

[21:28:30] <jazwec> reveal it. but somehow it always messes up the final output
