When the LiveDisplayZoomFactor is used as per the Scroll and Zoom Example, it Zooms the entire Image (including the Overlay objects like Text and Lines). Is there any method with which we can Zoom only the Video Image, still restoring the Overlay Objects as they were when the LiveDisplayZoomFactor is 1?

Thanks and Best Regards

IC Imaging Control does not offer a method for zooming the video image without the graphics. IC Imaging Control draws the overlay directly on the video images.

You may do not use the overlay bitmap of IC Imaging Control. You may use a Picturebox and draw the live image in it, using the ImageAvaialble event. Then you also need to implement the scroll and zoom functionality on the picture box (you can use the System.Drawing.Graphics functions for this) and draw you lines on the graphics on your own.

In order to draw the IC Imaging Control video images you can use the "Bitmap" property of the image buffer.

Dear Mr.Stefan,
Regarding the original Query as above...

By any chance is there any update done on the IC Imaging Control (w.r.t VB6/VB.NET) such that this function is now possible without using Picture Box method?

Thank you
Best Regards,

Since the Overlay is drawn directly on the camera images, there is no change in IC Imaging Control to meet your requirements.
