Image dataThere are several getters for various image data:
fetches an image from the FrameDetector of your choice.
XPP CsPad detector:
For an example of how to draw an image as a 2D root histogram, see the myana_cspad.cc example. Fast CCD camera:
Configures the information from the Fast CCD. Fills arguments with values depending on how the image/waveform data were taken. There is no PnCCD camera (used by CAMP):
This camera has 4 links, each link provides a 512 x 512 x 16 bit image. This function combines the four images to a single 1024 x 1024 x 16 bit image. |
