Visual Customization

All customization properties can be set as attributes on CropImageView (crop prefix):

<com.theartofdev.edmodo.cropper.CropImageView
  xmlns:custom="http://schemas.android.com/apk/res-auto"
  android:id="@+id/cropImageView"
  android:layout_width="match_parent"
  android:layout_height="0dp"
  android:layout_weight="1"
  custom:cropGuidelines="on"
  custom:cropShape="oval"
  custom:cropBorderLineColor="@android:color/holo_red_dark"
  custom:cropGuidelinesColor="@android:color/holo_green_dark"
  custom:cropBorderLineThickness="5dp"/>

or set for CropImageActivity using builder (set prefix):
Note: the dimension properties are all in pixels.

CropImage.activity(imageUri)
  .setGuidelines(CropImageView.Guidelines.ON)
  .setCropShape(CropImageView.CropShape.OVAL)
  .setBorderLineColor(Color.RED)
  .setGuidelinesColor(Color.GREEN)
  .setBorderLineThickness(getResources().getDimensionPixelSize(R.dimen.thickness))
  .start(this);

some are possible to change at run-time on CropImageView instance:

cropImageView.setGuidelines(CropImageView.Guidelines.ON);
cropImageView.setCropShape(CropImageView.CropShape.OVAL);

ScaleType

Default: FIT_CENTER
Options for scaling the bounds of cropping image to the bounds of Crop Image View.
Some options are affected by auto-zoom, if enabled.

• FIT_CENTER: Scale the image uniformly (maintain the image's aspect ratio) to fit in crop image view.
• CENTER: Center the image in the view, but perform no scaling.
• CENTER_CROP: Scale the image uniformly (maintain the image's aspect ratio) so that both dimensions (width and height) of the image will be equal to or larger than the corresponding dimension of the view (minus padding).
• CENTER_INSIDE: Scale the image uniformly (maintain the image's aspect ratio) so that both dimensions (width and height) of the image will be equal to or less than the corresponding dimension of the view (minus padding).

CropShape

Default: Rectangle
Set crop window shape to Rectangle or Oval, use FixAspectRatio for Square / Circle.

Guidelines

Default: on-touch
Whether the guidelines within the crop window will be displayed.

• off: no guidelines will be displayed.
• on: guidelines will always be displayed.
• on-touch: guidelines will be displayed when the crop window is touched.

AspectRatioX/Y

Default: 1 / 1
Sets the value of the aspect ratio, the ratio between the width and height dimensions of the crop window.

FixAspectRatio

Default: false
Is the aspect ratio can be freely changed by the user or is it fixed to set values.

AutoZoomEnabled

Default: true
Is auto-zoom feature is enabled: zoom-in when crop window is smaller than 50% of cropping image and zoom-out when larger than 65%.

MaxZoom

Default: 4
The maximum zoom-in allowed for auto-zoom.

InitialCropWindowPaddingRatio

Default: 0.1 (10%)
The padding of the initial crop window from the edges of the cropping image. If FixAspectRatio is set then the larger dimesion will be set while the smaller will adjust by aspect ratio.
Set to 0 for initial crop window to fully cover the cropping image.

BackgroundColor

Default: #77000000
The color of the crop overlay outside of crop window area, covering parts of the cropping image outside of the crop window.
Make sure the background has some transparency so the cropping image will be visible.

BorderLineColor

Default: #AAFFFFFF
The color of the crop window border lines.

BorderLineThickness

Default: 3dp
The thickness of the crop window border lines.

BorderCornerColor

Default: #FFFFFF
The color of the crop window corner lines.

BorderCornerThickness

Default: 2dp
The thickness of the crop window corner lines.
Set to 0 to remove.

BorderCornerOffset

Default: 5dp
Offset of the crop window corner lines from the border lines.
Set to 0 place on top of the border lines.

BorderCornerLength

Default: 14dp
The length of crop window corner lines from the crop window corner.

GuidelinesColor

Default: #AAFFFFFF
The color of guidelines inside the crop window.

GuidelinesThickness

Default: 1dp
The thickness of guidelines inside the crop window.

SnapRadius

Default: 3dp
An edge of the crop window will snap to the corresponding edge of the cropping image when the crop window edge is less than or equal to this distance away from the bounding box edge.
Set to 0 to disable snapping.

ShowCropOverlay

Default: true
Is the crop overlay, crop window with surrounding background, is shown over the cropping window.
Can be used to hide during frame transitions.

ShowProgressBar

Default: true
Is default progress bar UI is shown during async image loading and cropping.
Allow disabling to provide custom progress UX.

MinCropWindowWidth/Height

Default: 40dp/40dp
The minimum size the crop window can be.
Ensures proper crop window UI without its parts drawn over itself and too small for proper touch.
Auto-zoom enables to select very small parts without violating the minimum crop window size.
