Issue:

When attached an image with transparent background in ZWCAD, why the background is not displayed as background color (black by default)? Instead, it is displayed as white as the below figure shown.

Solution:

  1. Click Modify in the menu, and Object→Image→Transparency
    Or execute the command TRANSPARENCY.



  2. Select the image that needs to be modified, and enter transparency mode to ON.





  3. Another method is to press Ctrl+1 to call out the Properties panel, and modify the setting of Background transparency to Yes.
