Drawing a rectangle (or line, or bitmap) on the ca

2019-08-30 05:38发布

I'm working on a .NET CF 2.0 application that uses the camera, showing the preview and allowing the user to take a photo. I'm using the CameraCaptureDialog component and I wanted to draw a rectangle on the preview screen, but I wasn't able to do it... Any ideas? Do you think the Overlay mixer filter in DirectShow can be useful? If so, do you have any example? (The problem is I work on the CF 2.0, so many solutions that work ok for the normal framework here don't work...). Thanks in advance,

Giacomo

You need to look for samples showing VMR Mixer Bitmap capability and mixing presented video with custom overlay
