Usage

TakePhoto

This node is to take a photo in a given format directly from the Raspberry Pi Camera. Using the Filemode the image of the photo is stored into the file-system and msg.payload will give you the path and the filename including extension to the photo. In Buffermode the image will reside as a buffer in msg.payload. For the possible parameters see documentation under picamera parameter settings.
