Capturing image from Linx tablet's camera
lazarus / 39-Graphics

The Linx 8 and Linx 10 tablets use Windows 8 and can run 32 bit
Lazarus programs. They have 2 built in cameras.

Is it possible using Lazarus to capture an image from the outward
facing built in camera? eg. capture it to memory as a bmp/jpeg - that
could be displayed on screen in a timage, so it could be processed.
Ideally I'd want to capture and process an image from the camera
multiple times a second (and also play a sound, etc. if necessary
depending on results of the processing).

I have used the very nice pxl library for this !

Thanks. So I'd need to install that library first? Is there a list of
functions anywhere that it adds?

What function would I need to call with this library to capture the
image from the Linx 8 or Linx 10's camera? Also is there
documentation/examples of that function anywhere?

(Note the processing I'm asking about (currently) is quite simple
checking of the RGB values of each pixel for each captured image -
multiple times a second (or every so many pixels if it's not possible
ie. if that's too slow). Maybe that library has a faster way to do it
though).
