As you may know I have a Raspberry Pi and play with it from time to time. One of my hobby projects got to a state where I can show it to you:
For upcoming 16.4 MBS Xojo plugins, we now have a few classes to work with the camera on a Raspberry Pi. You can query available formats, select one and take pictures. We support both picture objects and directly capturing JPEG data. This way you can request image in right size and compressed and your application doesn't need to do this.
If you like to try, please email me soon.
