Krop

The library is a small widget for image cropping in Instagram-like style.

Gradle

Step 1. Add this in your root build.gradle

    allprojects {
        repositories {
            maven { url 'https://jitpack.io' }
        }
    }

Step 2. Add the dependency

    dependencies {
        compile 'com.github.avito-tech:krop:VERSION'
    }

If you like to stay on the bleeding edge, or use certain commit as your dependency, you can use the short commit hash or anyBranch-SNAPSHOT as the version

Demo

Please see the demo app for library usage example.

Usage:

Add KropView to your layout:

<com.avito.android.krop.KropView
    android:id="@+id/krop_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:krop_aspectX="1"
    app:krop_aspectY="1"
    app:krop_offset="24dp"
    app:krop_overlayColor="#aaffffff"/>

To set bitmap you need to crop, just use method:

kropView.setBitmap(bitmap)

Obtaining result

To get cropped bitmap, use getCroppedBitmap:

val bitmap = kropView.getCroppedBitmap()

or get selected area RectF and crop bitmap manually when you need it:

val rect = kropView.getCropRect()

Listeners

You may listen for cropping event, by defining CropListener:

    interface CropListener {

        fun onCrop(transformation: Transformation)

    }

Basic View Configuration

• Set an initial crop area's aspect ratio:

in XML layout:

app:krop_aspectX="4"
app:krop_aspectY="3"

or in code:

kropView.applyAspectRatio(aspectX = 4, aspectY = 3);

• Set overlay color:

in XML layout:

app:krop_overlayColor="#aaffffff

or in code:

kropView.applyOverlayColor(color = 0xaaffffff);

• Set minimum crop region offset (px):

in XML layout:

app:krop_offset="24dp"

or in code:

kropView.applyOffset(offset = 120);
