CropImageView

An ImageView that supports different kind of cropping rather than the only Android is currently supporting: centerCrop

Using this library, you can crop your desired image by sides described below:

Development idea borns at the point in [Kerad Games] we needed images cropped by somewhere no matter the image size.

The original images we had to deal with (we wanted the half size of the ball shown whatever screen size), below

Here are some screenshots what we got thanks to this widget :-)

Usage

Step 1

Gradle

dependencies {

 compile 'com.cesards.android:cropimageview:1.0.2.1' 
}

Maven

<dependency>
 <groupId>com.cesards.android</groupId>
 <artifactId>CropImageView</artifactId>
 <version>1.0.2</version>
 <type>aar</type> </dependency>

Step 2

Define in xml:

<com.cesards.cropimageview.CropImageView
 xmlns:custom="http://schemas.android.com/apk/res-auto"
 android:id="@+id/imageView1"
 android:src="@drawable/photo1"
 custom:crop="value" />

where value can take values

topLeft|centerLeft|bottomLeft|topRight|centerRight|bottomRight|centerTop|centerBottom

Or in code:

final CropImageView cropImageView = new CropImageView(CropActivity.this);
 final Resources res = getResources();
 cropImageView.setImageDrawable(res.getDrawable(images[position]));
 final CropImageView.CropType cropType = imageCrops[position]; cropImageView.setCropType(cropType);

Performance tests (using Hugo)

Center Crop Sample (ImageView)

V/TestForegroundImageView? ? setFrame(l=0, t=0, r=1080, b=1557) V/TestForegroundImageView? ? setFrame [0ms] = true V/TestForegroundImageView? ? setFrame(l=1080, t=0, r=2160, b=1557) V/TestForegroundImageView? ? setFrame [0ms] = true V/TestForegroundImageView? ? setFrame(l=0, t=0, r=1080, b=1557) V/TestForegroundImageView? ? setFrame [0ms] = false V/TestForegroundImageView? ? setFrame(l=1080, t=0, r=2160, b=1557) V/TestForegroundImageView? ? setFrame [0ms] = false V/TestForegroundImageView? ? setFrame(l=0, t=0, r=1080, b=1701) V/TestForegroundImageView? ? setFrame [0ms] = true V/TestForegroundImageView? ? setFrame(l=1080, t=0, r=2160, b=1701) V/TestForegroundImageView? ? setFrame [0ms] = true` 

Custom Crop Sample (CropImageView)

V/TestForegroundCropImageView? ? setFrame(l=0, t=0, r=1080, b=1557) V/TestForegroundCropImageView? ? setFrame [0ms] = true V/TestForegroundCropImageView? ? setFrame(l=1080, t=0, r=2160, b=1557) V/TestForegroundCropImageView? ? setFrame [0ms] = true V/TestForegroundCropImageView? ? setFrame(l=0, t=0, r=1080, b=1557) V/TestForegroundCropImageView? ? setFrame [0ms] = false V/TestForegroundCropImageView? ? setFrame(l=1080, t=0, r=2160, b=1557) V/TestForegroundCropImageView? ? setFrame [0ms] = false V/TestForegroundCropImageView? ? setFrame(l=0, t=0, r=1080, b=1701) V/TestForegroundCropImageView? ? setFrame [0ms] = true V/TestForegroundCropImageView? ? setFrame(l=1080, t=0, r=2160, b=1701) V/TestForegroundCropImageView? ? setFrame [0ms] = true 

Results: code used does not cause overhead in the UI thread.

ChangeLog

• 1.0.2.1 (2015-10-22)
  • ImageView crashes in devices with API < 18 due to a @TargetApi annotation
• 1.0.2 (2015-10-22)
  • Changed minSdkVersion to 7
  • Solved a bug related with ImageView and API < 18.
• 1.0.1 (2015-02-17)
  • Changed Samples UI and removed unused resources.
  • Added performance tests to Samples.
  • Added code styles for contributions.
  • Improved CropImageView widget. Removed onLayout() overhead. ImageView onLayout() is empty, so we only need logic in setFrame() method.
