The build tarball of zbar_jll contains two products:

• zbarimg

This repository wraps the content of libzbar.so via Clang.jl, and provides a Julia interface for the binary product zbarimg.

Installation

using Pkg
Pkg.add("ZBar")

Examples

Pass the arguments to zbarimg:

using ZBar
res = execute(`$(zbarimg()) --help`)
println(res.stdout, '\n', res.code, '\n', res.stderr)

Or use the wrappers decodeimg and decodesingle

using ZBar, QRCoders, Test
# decode a single QR-Code
exportqrcode("hello world!", "hello.png")
@test decodesingle("hello.png") == "hello world!" # "hello world!"

# decode all QR-Codes
exportqrcode(["hello", "world"], "hello_world.gif")
@test decodeimg("hello_world.gif") == ["hello", "world"] # ["hello", "world"]
