1 | # TextRecognizer
2 | This library extend [google vision](https://developers.google.com/vision/) . And initilay it read text from image.
3 | for reading text from image you have to give image **Uri** or **Bitmap**.
4 |
5 | Sample
6 | 
7 | # Setup
8 | Setup part is simple
9 |
10 | # Root Gradle
11 | ```sh
12 | allprojects {
13 | repositories {
14 | ...
15 | maven { url 'https://jitpack.io' }
16 | }
17 | }
18 | ```
19 |
20 | # App Gradle:
21 |
22 | ```sh
23 | dependencies {
24 | implementation 'com.github.mahimrocky:TextRecognizer:1.0.0'
25 | }
26 | ```
27 |
28 | # Api
29 | ```sh
30 | TextScanner.getInstance(this)
31 | .init()
32 | .load(uri) // uri or bitmap
33 | .getCallback(new TextExtractCallback() {
34 | @Override
35 | public void onGetExtractText(List textList) {
36 | // Here you will get list of text
37 |
38 | }
39 | });
40 | ```
