v.capture() doesn't work with pptk

[ricky3087]

Hi,

I want to save the view of the loaded pointcloud in the viewer as a png file. I tried using v.capture() but it just gives black image.

Am I missing something `?

Thanks

You can "fix" this yourself by adding a viewer.wait() or a time.sleep(20). It appears, that the capture is faster than the building of the point cloud.

add wait() before or after capture()?

Hi,

I had this issue when I played with the background color, e.g. v.set(bg_color = [0, 0, 0, 0]) It worked when the alpha value is 1, like this: v.set(bg_color = [0, 0, 0, 1])

I found this solution on a StackOverflow thread: https://stackoverflow.com/questions/70037260/python-pptk-screen-capture-is-empty
