# Android Image Kit [](https://travis-ci.org/jeziellago/android-image-kit) [](https://jitpack.io/#jeziellago/android-image-kit)
Open-source library for image processing in Android.
- Image color space conversion
- Gaussian Blur Filter
- Bitmap to RGB Matrix
- Draw Text, Rect, Circle, Points
### Add in your project
Step 1. Add the JitPack repository to your build file
- Add it in your root build.gradle at the end of repositories:
```gradle
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
```
Step 2. Add the dependency:
```gradle
dependencies {
implementation 'com.github.jeziellago:android-image-kit:v0.1-alpha'
}
```
## Examples:
### RGB to Gray Scale
```kotlin
val grayImage = Image(rgbImage)
.convertToGray()
.toBitmap()
```
### Bitmap to RGB Matrix
```kotlin
val rgb3dMatrix = Image(imageBitmap).convertToRGBMatrix()
```
### Resize
```kotlin
val resizedBitmap = Image(imageBitmap)
.resize(newWidth = 200f, newHeight = 250f)
.toBitmap()
```
### Reshape to 4D (used in machine learning)
```kotlin
val image4dArray = Image(imageBitmap).reshapeTo4D()
```
### Gaussian Blur Filter
```kotlin
val gaussianBlurImage = GaussianBlur(context).apply(sourceImage)
```
### Drawing Text
```kotlin
val bitmap = ImagePaint(sourceBitmap)
.drawText(text = "Draw text here",
textSize = 50f,
textColor = Color.WHITE,
positionX = 50f,
positionY = 200f)
.toBitmap()
```
### Drawing Points
```kotlin
val bitmap = ImagePaint(sampleImage)
.drawPoints(points = 10f, 20f, 30f, ...)
.toBitmap()
```
### Drawing Rect
```kotlin
val bitmap = ImagePaint(sampleImage)
.drawRect(rect = rectObject)
.toBitmap()
```
