Enhancement Description Related API
Login status check When creating whiteboards, destroying whiteboards, or retrieving the whiteboard list, check whether the user has logged in, and throw out the error 3010001 if negative.
Error prompt optimization Optimized the prompt of the error that the physical size of the parent container is 0 when creating a whiteboard.

Bug fixes

Fixed the following issues:

  1. The whiteboard background image is not displayed correctly for the users who enter the room later.
  2. The method attachView fails after the DOM of the whiteboard is deleted.
  3. When the whiteboard adapts to the size of the parent container, the coordinates of the graphics primitives are not adjusted correctly.
  4. When the whiteboard adapts to the size of the parent container, content on the scrollable whiteboard is not rendered correctly.

  • 3050003: No permission to create graphics primitives using gestures.
  • 3050004: No permission to edit graphics primitives created by others.
  • 3050005: No permission to move graphics primitives created by others.
  • 3050006: No permission to delete graphics primitives created by others.
  • 3050007: No permission to clear graphics primitives.
 -
Optimization on the indication of graphics primitives bulk selection When selecting multiple graphics primitives at a time, each selected graphics primitive is indicated separately with a rectangular frame, so that which graphics primitives are selected can be seen clearly and intuitively. -
Feature optimization Optimized the undo and redo features. -

Bug fixes

Fixed the following issues:

  1. When users who join the room later click on an animated PPT, the current animation step goes back.
  2. Users who join the room later can't operate cross-page primitives.
  3. Issues with simultaneous operations of scrolling, page turning, and drawing.
  4. Other known issues.
