How to prevent image insertion in Angular RichTextEditor?

When working with Angular RichTextEditor, there may be scenarios where you need to restrict users from uploading or pasting images into the editor. This can be essential for maintaining the integrity of the content or adhering to specific content policies. Below is a guide on how to disable the insertion of images in a RichTextEditor.

Preventing Image Uploads

To prevent users from uploading images through the image toolbar, you can utilize the actionBegin event. Within this event, you can set the e.cancel property to true when the requestType is ‘Image’. This will effectively block the upload action.

Here is a code snippet that demonstrates how to implement this:

<ejs-richtexteditor
    id="defaultRTE"
    (actionBegin)="actionBegin($event)"
    [pasteCleanupSettings]="pasteCleanupSettings">
</ejs-richtexteditor>

public actionBegin(e) {
  if (e.requestType == 'Image') {
    e.cancel = true;
  }
}

Disabling Pasting of Images

If you want to prevent users from pasting images into the RichTextEditor, you can use the deniedTags property within the pasteCleanupSettings. By specifying ['img'] as a denied tag, the editor will not allow image tags to be pasted into the content.

Here is how you can set up the pasteCleanupSettings:

public pasteCleanupSettings = {
  deniedTags: ['img'],
};

By combining both methods, you can ensure that images are neither uploaded through the toolbar nor pasted from the clipboard.
