# Java DotCode Reader
2+
These samples demonstrate how to decode **DotCode** using the [Dynamsoft Barcode Reader SDK](https://www.dynamsoft.com/barcode-reader/downloads/).
3+
4+
## License Key
5+
Get a [valid license](https://www.dynamsoft.com/customer/license/trialLicense/) and update the code in `src/main/java/com/java/barcode/App.java`:
6+
7+
```java
8+
BarcodeReader.initLicense("LICENSE-KEY");
9+
```
10+
11+
## Usage
12+
13+
- Command-line
14+
15+
```bash
16+
mvn clean package
17+
java -cp target/test-1.0-SNAPSHOT-jar-with-dependencies.jar com.java.barcode.App ../../../../images/dotcode.png
18+
```
19+
20+
- OpenCV
21+
22+
1. Install the OpenCV JAR file to your local Maven repository:
23+
24+
```bash
25+
cmd
26+
mvn install:install-file -Dfile=opencv-430.jar -DgroupId=org -DartifactId=opencv -Dversion=4.3.0 -Dpackaging=jar
27+
```
28+
29+
2. Build and run the project.
30+
31+
```bash
32+
mvn clean package
33+
java -cp target/test-1.0-SNAPSHOT-jar-with-dependencies.jar com.java.barcode.App
34+
```
