Re-Size QR Code

[PeterA1]

Hi,

I want to re-size the .png produced for a QR code. If I apply a scale the QR code produced is smaller, but the QR code has white space to the top and right?

Any help appreciated.

Can you provide some example input parameters/options so I can understand the issues you are seeing?

Here's the version # and Options currently in use.

Using bwip-js@1.1.1

There is a bug here that I believe we also saw in issue #53. But fortunately for your use case, there is a work around until I can track down the error.

At scale factor 1, each "module" of the qr-symbol is a 2x2 square. At scale factor 2, each module is a 4x4 square. The only possible size in between those would use a scale factor of 1.5. Specifying scale:1.65 is causing the extra padding.

I just verified that this works without adding padding using both the online demo and the online API. For example, this produces a qr-symbol with a 3x3 module size and no extra padding:

Thanks, the 1.5 Ratio sorted the Skewed Padding.

However I did notice that if I set Options { scale: 1.5, paddingwidth: 5, paddingheight: 5 } then I got...

It turns out the padding works when the scale factor is an integer, but not when fractional. I have a fix for the issue and will roll-out a new release later today.

fractional still not work, @metafloor
