ZXingCPP

ZXingCPP.jl is a Julia wrapper for the C++ library zxing-cpp. It is an open-source, multi-format linear/matrix barcode image processing library implemented in C++.

ZXingCPP.jl provides fast and accurate barcode detection, decoding and creation within Julia.

ZXingCPP.jl integrated with Images.jl and OpenCV.jl. Both packages can used to read and write barcode images.

Usage

Using Images.jl

using ZXingCPP

using ImageCore
using FileIO
using ImageIO

Create:

f = ZXing_BarcodeFormat_QRCode
co = CreatorOptions(f)
bc = Barcode("HELLO WORLD", co)
print(bc)

Write:

wo = WriterOptions(; scale=10)
zimg = write_barcode_to_image(bc, wo)
jimg = Matrix(zimg)
save("barcode.png", jimg)

Read:

img = load("barcode.png")
ro = ReaderOptions(; formats=ZXing_BarcodeFormat_QRCode)
bcs = read_barcodes(img, ro)
print(bcs)

Using OpenCV.jl

using ZXingCPP
using OpenCV

Create:

f = ZXing_BarcodeFormat_QRCode
co = CreatorOptions(f)
bc = Barcode("HELLO WORLD", co)
print(bc)

Write:

wo = WriterOptions(; scale=10)
zimg = write_barcode_to_image(bc, wo)
cvimg = OpenCV.Mat(zimg)
OpenCV.imwrite("barcode.png", cvimg)

Read:

img = OpenCV.imread("barcode.png", OpenCV.IMREAD_UNCHANGED)
ro = ReaderOptions(; formats=ZXing_BarcodeFormat_QRCode)
bcs = read_barcodes(img, ro)
print(bcs)
