Why does this VBA-generated QR-Code stutter? (barcode-vba-macro-only)

为君一笑 提交于 2019-12-22 11:29:34
问题 Context I am using barcode-vba-macro-only (mentioned in this SO post) in MS Excel 2010 to generate a QR code. (The bar code will be used to facilitate paying a bill using Girocode, but that is not important here, except to say I need to structure the input exactly the way shown below.) The problem The VBA macro creates great QR-Codes, but somehow, when given certain input, the output (encoded in the QR code) "stutters", i.e. repeats part of the text. E.g., when given this input: BCD 001 1 SCT

问题 I am working on an app that reads QR codes and I need the orientation of the code. The ZXING source states that the orientation can be obtained from a hashtable ResultMetaData through the key ORIENTATION Now, my issue is that the getResultMetaData() is not returning any results when I run the following: orientation = (Integer) Returned[v].getResultMetadata().get("ORIENTATION"); However, the line directly above this, points = Returned[v].getResultPoints(); Works just fine, so I know that the

Reverse engineering of mixed tiles of QR code

纵然是瞬间 提交于 2019-12-21 23:18:09
问题 I have 25 tiles, each 94x94px, of previously splitted QR code (470x470px). I need to recover QR code by combining all possible tiles into one image. 3 tiles suppose to be "anchors" or big squares located at NW, NE and SW corners. Therefore we have remaining 22 tiles with unknown position. How to generate all possible combinations using ImageMagick? UPDATE: My first approach is to generate text file (which later will be fed to ImageMagick as input) with all combinations, taking into account
