There are several getters for fetching image data from the xtc file. Depending on which camera was in use, one of these should be appropriate:

• Opal1000 camera:
  getOpal1kValue getFrameValue (an alias getOpal1kValue is provided for getFrameValuebackward compatibility)

• Pulnix6740CL camera:
  getTm6740Value getFrameValue (an alias getTm6740Value is provided for getFrameValuebackward compatibility)

• FrameDetector (general):

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

  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. Specify the detector (using an appropriate enum).

  Code Block
  Available frame detectors: AMO: AmoVmi - velocity map imaging AmoBps1 - beam position screen AmoBps2 - beam position screen SXR: SxrBeamlineOpal1 SxrBeamlineOpal2 SxrEndstationOpal1 SxrEndstationOpal2 SxrFccd XPP: XppSb1PimCvd XppMonPimCvd XppSb3PimCvd XppSb4PimCvd

• Fast CCD camera:

  Code Block

  int getFccdConfig(FrameDetector det, uint16_t& outputMode, bool& ccdEnable, bool& focusMode, uint32_t& exposureTime, float& dacVoltage1, float& dacVoltage2, float& dacVoltage3, float& dacVoltage4, float& dacVoltage5, float& dacVoltage6, float& dacVoltage7, float& dacVoltage8, float& dacVoltage9, float& dacVoltage10, float& dacVoltage11, float& dacVoltage12, float& dacVoltage13, float& dacVoltage14, float& dacVoltage15, float& dacVoltage16, float& dacVoltage17, uint16_t& waveform0, uint16_t& waveform1, uint16_t& waveform2, uint16_t& waveform3, uint16_t& waveform4, uint16_t& waveform5, uint16_t& waveform6, uint16_t& waveform7, uint16_t& waveform8, uint16_t& waveform9, uint16_t& waveform10, uint16_t& waveform11, uint16_t& waveform12, uint16_t& waveform13, uint16_t& waveform14);

  Configures the information from the Fast CCD. Fills arguments with values depending on how the image/waveform data were taken. There is no getFccdValue in main.hh, so I think you need to use getFrameValue for this .
  

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

  Fetches the FCCD image data. Specify the detector (only SxrFccd is available as of 2012).

• PnCCD camera (used by the CAMP collaboration):

  Code Block
  int getPnCcdValue (int deviceId, unsigned char*& image, int& width, int& height );

  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.
  deviceId can be PnCcd0 or PnCcd1, width and height are the number of pixels in each direction.
