Tom da1b656868 Encode mixed numeric/alphanumeric data segments as one alphanumeric data segment if that's more efficient. Also add error check to NewWithForcedVersion(): Check if the content is too large for the requested QR code version. 2020-06-17 20:51:04 +01:00

Tom cb3bf7ba5a Add DisableBorder option to disable the QR Code quiet zone entirely, thus no more margins/borders. Defaults to borders for compatibility. 2019-10-17 17:33:59 +01:00

Tom 80e59a6a81 Fix scaling of QR codes in fixed sized images. 
Previously each QR code module was the same number of pixels in width/height; this leads to some unfavourably small QR codes generated, with lots of white space.

Now, we map each image pixel to the nearest "pixel" in the QR code instead. QR code modules can now vary width/height by a pixel or two.
