CropMe

Gradle

dependencies {
    implementation 'com.github.takusemba:cropme:x.x.x'
}

Usage

This is an Android library for cropping images. Move images smoothly, and crop images precisely.

Use CropView in your xml file.

  <com.takusemba.cropme.CropLayout
    android:id="@+id/crop_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:cropme_background_alpha="80%"
    app:cropme_frame_height_percent="80%"
    app:cropme_frame_width_percent="80%"
    app:cropme_max_scale="2.0"
    app:cropme_overlay_shape="rectangle"
    app:cropme_with_border="true"
    >

Set your image

cropView.setUri(uri);
// or
cropView.setBitmap(bitmap)

Crop it!

cropLayout.addOnCropListener(object : OnCropListener {
  override fun onSuccess(bitmap: Bitmap) {
    // do somethhing with bitmap.
  }

  override fun onFailure(e: Exception) {
    // do error handling.
  }
})
    
cropView.isOffFrame() // optionally check if the image is off the frame.

cropView.crop() // crop image

Custom Overlay

If you want to show a custom overlay, you can customize the Overlay by extending CropOverlay.

You can see more detail in app module.

class CustomCropOverlay @JvmOverloads constructor(
    context: Context,
    attrs: AttributeSet? = null,
    defStyleAttr: Int = 0,
    cropOverlayAttrs: AttributeSet? = attrs
) : CropOverlay(context, attrs, defStyleAttr, cropOverlayAttrs) {

  override fun drawBackground(canvas: Canvas, paint: Paint) {
    // draw background
  }

  override fun drawCrop(canvas: Canvas, paint: Paint) {
    // draw croppling frame
  }

  override fun drawBorder(canvas: Canvas, paint: Paint) {
    // draw borders
  }
}
