# EasyCodeReaderLive_Pylon_Console

This code sample sample shows how to use Open eVision in a live application to read Barcodes, Data Matrix codes or
QR codes. It is mostly aimed at being a demonstration of Open eVision on embedded platforms like smart cameras.

This code sample is available in many different variants. The one you are currently reading is using:

* A console displayer that will output the codes on the command line.
* The Pylon 5 library (a library specific to smart cameras produced by Basler).

Please note that the current sample was distributed along with other similar samples providing other connectivity
possibilities. Please consult those other samples if the current one is not appropriate for your use case.

## Dependencies

### Open eVision

This sample depends on Open eVision. Please install it in a version suitable for your platform.

All Open eVision releases are available at this address: https://www.euresys.com/en/Support/Download-area

### GCC


This sample necessitates a GCC building solution able to compile C++ 17.


To install it on a Debian-based operating system use this command:

```
sudo apt install build-essential
```

### CMake

This sample necessitates CMake >= 3.1.0 .

To install it on a Debian-based operating system use this command:

```
sudo apt install cmake
```

### Pylon

This sample necessitates the Pylon library. The sample was tested only with the version 5.2 of the library.

If you are using a smart camera that recommends the usage of the Pylon library it is quite likely already installed
on your camera. If that is not the case please consult the documentation of your smart camera.

## Switching type of code reader (Barcodes, Matrixcodes or QRcodes)

This project support multiple type of codes, but only one of them at a given time. By default it will read Barcodes.

If you want to change the type of code that this sample will read modify the `ProcessingHandler.cpp` file and change
the following block of code according to your need:

```
// Choose one processing in BarCode, MatrixCode or QRCode
#define BarCodeProcessing
//#define MatrixCodeProcessing
//#define QRCodeProcessing
```

## Compiling this sample

Use the following commands in order to compile your project:

```bash
mkdir build
cd build
cmake ..
make -j2
```

Alternatively, you could build the sample by using Qt Creator. To do so, open the CMakeLists.txt file in Qt Creator.

## Using this sample

When launched this sample will capture data from the camera and output a code in the command line if one is found.

This sample is intended to be run on low ressources computers without a graphical interface and does not provide video
confirmation. If you want to have a video confirmation you should use one of the Qt samples distributed along with the
current sample instead.
