There are several getters for various image data:

getFrameValue Gives you the width and height (in pixels) of the image, and a pointer to the start of the pixel array of a Pds::Camera::FrameV1 object.
getOpal1kValue an alias for getFrameValue
getTm6740Value an alias for getFrameValue
getCspadQuad Gives you a pointer to the first position in the array of pixel data from the XPP CsPad detector .(or alternatively you can get a pointer to the Pds::CsPad::ElementV1 object itself).

int getFrameConfig   (FrameDetector det);

 To get an image Frame
 ------------------------------------------------------------------------------------------------------

 int getFrameConfig   (FrameDetector det);

 -->  Checks that the xtc file has got data from this device.

 int getFrameValue(FrameDetector det, int& frameWidth, int& frameHeight, unsigned short*& image );

 --> fetches an image from the FrameDetector of your choice.
     Note that 
     Specify the detector (using an appropriate enum), give pointers to
                  int frame width, frame height and short imgage of the Camera::FrameV1.

fetches an image from the FrameDetector of your choice.
Specify the detector (using an appropriate enum), and getFrameValue will direct your pointers to the width and height of the image as well as the start of the pixel array.

 Other functions that do not require (or have) configuration
 ------------------------------------------------------------------------------------------------------


 int getFeeGasDet  (double* shotEnergy);
 --> Gives you the shot energy to the array shotEnergy[4]. This information is obtained from
     the Front End Enclosure Gas Detector.



 int getEBeam(double& charge, double& energy, double& posx, double& posy,
              double& angx, double& angy);
 int getEBeam(double& charge, double& energy, double& posx, double& posy,
              double& angx, double& angy, double& pkcurr);
  --> Gives electron beam values for each of these doubles. The measured charge of the beam (in nC),
      the measured energy of the beam (in MeV), the 2D position of the beam (in mm) away from the origin
      (nominal beam position), and 2D angular position (in mrad) off the assumed direction. and the
      pkcurr = current? in (Amps)



 int getPhaseCavity(double& fitTime1, double& fitTime2, double& charge1,  double& charge2);
 --> Gives you the phase cavity fit time (low and high?) and charges (before and after?).


 int getPnCcdValue (int deviceId, unsigned char*& image, int& width, int& height );
 --> The PnCCD camera (used by CAMP) 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.


 int getEvrDataNumber();

 int getEvrData    ( int id, unsigned int& eventCode, unsigned int& fiducial, unsigned int& timeStamp );
     - eventCode tells you something about the beam quality of this event. Usually the event code is  140,
       meaning electrons were produced upstream (beam was on). It does not tell you about the photon status.
       Other codes:

     - fiducial
     - timestamp

 Get integers, floats, strings from any EPICS channel (PV = process variable)
 int getPvInt      (const char* pvName, int& value);
 int getPvFloat    (const char* pvName, float& value);
