Rotate Image Angle

Rotate Image Angle Node Documentation

The Rotate Image Angle node in AugeLab Studio is used to rotate an input image by a specified angle.

Node Overview

The Rotate Image Angle node takes an input image and rotates it by a specified angle. You can use the slider in the node's UI to adjust the rotation angle. The node provides an option to crop the image to remove the background after rotation.

Node Properties

  • Node Title: Rotate Image Angle
  • Node ID: OP_NODE_ROTATE_IMAGE_ANGLE

Inputs

The Rotate Image Angle node has the following input socket:
  1. 1.
    Input Image: The input image to be rotated.

Outputs

The Rotate Image Angle node has the following output socket:
  1. 1.
    Output Image: The resulting image after applying the rotation.
The output image will have the same dimensions as the input image.

UI Controls

The Rotate Image Angle node provides the following UI controls:
  • Crop Background: A checkbox to enable or disable background cropping. When enabled, the node will crop the image to remove the background after rotation. When disabled, the original image with rotation will be output.
  • Angle: A slider to adjust the rotation angle of the image. You can slide the control to specify the desired rotation angle.

Usage

  1. 1.
    Drag and drop the Rotate Image Angle node from the node library onto the canvas in AugeLab Studio.
  2. 2.
    Connect the input image to the Input Image input socket of the Rotate Image Angle node.
  3. 3.
    (Optional) Adjust the rotation angle using the Angle slider in the node's UI.
  4. 4.
    (Optional) Check the Crop Background checkbox to enable background cropping.
  5. 5.
    Run the pipeline.
  6. 6.
    The Rotate Image Angle node will rotate the input image by the specified angle.
  7. 7.
    If background cropping is enabled, the node will crop the image to remove the background after rotation.
  8. 8.
    The resulting image will be output through the Output Image output socket.
  9. 9.
    Use the output image for further analysis or display it in the console.

Notes

  • The Rotate Image Angle node requires an input image.
  • The rotation angle can be adjusted using the Angle slider in the node's UI. The slider allows you to specify the rotation angle in the range of 0 to 360 degrees.
  • By default, the node crops the image to remove the background after rotation. You can enable or disable background cropping using the Crop Background checkbox.
  • If background cropping is enabled, the node uses the largest_rotated_rect() and crop_around_center() functions to crop the image around its center after rotation.
  • The Rotate Image Angle node uses OpenCV's cv2.getRotationMatrix2D() and cv2.warpAffine() functions to apply the rotation to the image.
  • The resulting image will have the same dimensions as the input image, but with the applied rotation.
That concludes the documentation for the Rotate Image Angle node in AugeLab Studio. This node allows you to rotate an image by a specified angle and provides an option to crop the image after rotation.
