Disable Crop Area Resizing

[Brian Pautsch]

We're using the ImageEditor to crop images and it works great, but we don't want the user to change the crop area size (block grabbing corner white circles and resizing). We thought OnSelectionResizeStart could be used to block it, but it doesn't work. When that event is used, the crop area disappears completely.

We want the crop area to display with the white circles in the corners, but block dragging/resizing the crop area. We just want the users to move the image up/down and zoom in/out and then crop the area inside the crop area.

Please advise. Thanks!

Hi Brian Pautsch,

 

We have included the fix for the issue "Unable to prevent the Crop Resizing using OnSelectionResizeStart" with our release version 33.2.10v . So please upgrade your package to the latest to resolve the issue from your end.

 

Release Notes : Essential Studio for Blazor Release Notes - v33.2.10

 

Root Cause :

• ⁠Resize prevention using OnSelectionResizeStart failed due to async interop in the drag lifecycle, causing timing issues where resize logic executed before the cancel flag was applied.
