★How to insert transparent images in ZWCAD

Issue: 

Why does the inserted company logo display with a visible background (Fig 1) instead of a transparent background that blends with the CAD environment,
and how can the border be removed (Fig 2)?

Fig 1: Actual effect

Fig 2: Expected effect

Solution:

1. First, ensure the source image itself has a transparent background.
   You can verify this using the Windows Paint tool (a checkerboard pattern indicates transparency).
   
2. In ZWCAD, select the inserted image object. Press Ctrl+1 to open the Properties panel and set Background Transparency to Yes.
   
3. Enter the command IMAGEFRAME in the command line and set the value to 0 to hide the border (achieving the expected result).
   You can adjust this value (0, 1, or 2) based on your specific needs.
