Render ImageEditor in Dialog in JavaScript ImageEditor control

02 Feb 2023 / 3 minutes to read

Image Editor is rendered within a dialog and opens an image by passing its URL path to the open method of the Image Editor control.

The following operations are supported in the Image Editor:

  • Selection : Multiple selection options are available. The selection region can be a square or circle, customized to various aspect ratios, and customized by dragging and resizing.
  • Crop : The image can be cropped based on the selection.
  • Rotate : The image can be rotated both clockwise and anticlockwise by 90 degrees.
