| FileDir | false | false | Scalar | READ_WRITE | Tango::DEV_STRING | OPERATOR | directory path to store image files in - the directory must exist - the server will check if the user running the server has write permissions for this directory, if not, the device will go to state fault / throw an exception - the attribute is memorized (last written value stored in tango db and read from there at server startup) |
| FilePrefix | false | false | Scalar | READ_WRITE | Tango::DEV_STRING | OPERATOR | String prefixed to file names (memorized attribute) |
| FileStartNum | false | false | Scalar | READ_WRITE | Tango::DEV_ULONG | OPERATOR | Start number for files: - not initialized - incremented after every file - range 0 - 999999 |
| FilePostfix | false | false | Scalar | READ_WRITE | Tango::DEV_STRING | OPERATOR | file postfix (determines file format). Supported file formats at time of writing are: bmp jpg/jpeg png ppm pbm pgm tif/tiff xbm xpm bin: raw data as received from camera nx: nexus hdf5 files |
| FileSaving | false | false | Scalar | READ_WRITE | Tango::DEV_BOOLEAN | OPERATOR | if set to true, acquired images will be saved to files. Can be set / reset during acquisition. |
| TuneMode | false | false | Scalar | READ_WRITE | Tango::DEV_USHORT | EXPERT | Mode for adjusting camera frame rate: 0 = no adjustment 1 = frame rate will be set to the maximum number of frames the server can process 2 = frame rate will be set so that the server will consume max. MaxLoad % cpu time |
| MaxLoad | false | false | Scalar | READ_WRITE | Tango::DEV_DOUBLE | EXPERT | Max. allowed cpu load if TuneMode is set to 2 |
| ViewingMode | false | false | Scalar | READ_WRITE | Tango::DEV_SHORT | OPERATOR | How camera data are written to attributes: 0 : nothing is written to any attributes 1: data are converted to 8-bit greyscale and written to Image8 2: data are converted to 16-bit greyscale and written to Image16 3: data are not converted and written to ImageRaw (ImageRaw dimensions will alway be ImageSize (in bytes) x 1). 4: data are converted to RGB-JPEG and written to ImageEnc 5: ata are converted to RGBA and written to ImageRGB Note: - not all pixel formats can be converted to 16-bit greyscale. An exception will be thrown if the current camera pixel format cannot be converted. - pixel formats Mono10/12/14/16 will not be converted at all when ViewingMode is 2. Data are written to the attribute `as is`. |
| BinComment | false | false | Scalar | READ_WRITE | Tango::DEV_STRING | OPERATOR | This goes as a comment into files of type nx (c.f FilePostfix). Max. length 256 chars. |
| ImageEnc | false | false | Scalar | READ | Tango::DEV_ENCODED | OPERATOR | JPEG encoded representation of the acquired image(s). Attribute is written if ViewingMode is set to 4. |
| FramesPerNXFile | false | false | Scalar | READ_WRITE | Tango::DEV_ULONG | OPERATOR | Max. number of frames written to one file if file format is nx. A new file will be created whenever this value is surpassed. 0 means all frames go into one file. |
| NXFileCompression | false | false | Scalar | READ_WRITE | Tango::DEV_SHORT | OPERATOR | Caveat utilitor ! This works, but CPU load and memory usage might increase a lot. And if you collect files with compression enabled for a long time the OS might kill the server. It all depends on PixelFomat, ImageSize and FrameRate. So: test before using this in experiment setups. |
| BayerToGray | false | false | Scalar | READ_WRITE | Tango::DEV_BOOLEAN | OPERATOR | if set to true, bayer pixel formats will be saved as greyscale images. Bayer Be aware that saving 16bit mono images is only possible with formats tiff and nx. |
| QueuedFrames | false | false | Scalar | READ | Tango::DEV_ULONG64 | OPERATOR | Number of frames stored in the servers queue which have not been processed (i.e. written to file or to attribute). Normally this value should be small (while acquisition is running it will never go below 1) It may fluctate a little, but should not be constantly increasing. If this is the case, the server will use up memory and eventually be killed by the OS. To remedy this, your options are - lower the framerate - or set property QueueSizeMax to a value> 0 (and read the docs) - or buy a faster computer |
| MaxQueuedFrames | false | false | Scalar | READ | Tango::DEV_ULONG64 | OPERATOR | Maximum number of frames stored in the servers queue which had not been processed (i.e. written to file or to attribute). If this value keeps on increasing while acquisition is running make things run slower. Otherwise the server will use up all the memory there is. The servers maximum queue size can be set with property QueueSizeMax. |
| DiscardedFrames | false | false | Scalar | READ | Tango::DEV_ULONG64 | OPERATOR | Number of frames not put into the servers. Discarding frames may happen if the servers internal queue size was limited with property QueueSizeMax and the queue is filled up to this size when a frame arrives from the camera. |
| FramesProcessed | false | false | Scalar | READ | Tango::DEV_ULONG64 | OPERATOR | Number of frames written to file / attribute and removed from the servers internal queue |
| MaxFramesPerQueue | false | false | Scalar | READ | Tango::DEV_ULONG64 | OPERATOR | Maximum number of frames which can be stored in the servers queue. The number depends on - the size you set for property QueueSizeMax - the selected pixelformat - the size of the image |
| FramesPerSingleAcquisition | false | false | Scalar | READ_WRITE | Tango::DEV_ULONG | OPERATOR | Max. number of frames to collect for a call of StartSingleAcquisition. The server will reset this value to 1 if you run StartAcquisition. |
| BrokenFrames | false | false | Scalar | READ_WRITE | Tango::DEV_ULONG64 | OPERATOR | Number of invalid frames received from the camera. The value will be 0 at server start. It`s writable so you can reset it. |
| DisplayBrokenFrames | false | false | Scalar | READ_WRITE | Tango::DEV_BOOLEAN | OPERATOR | If set to true, broken frames (where the image data are all set to 0, i.e. a black image) will be written to the Image set to INVALID. Otherwise they will be skipped. |
| StoreBrokenFrames | false | false | Scalar | READ_WRITE | Tango::DEV_BOOLEAN | OPERATOR | If set to true, broken frames will be written files. In nx files, the value in `validity` will contain a value < 0, the image data will be set to 0. In other files, only this value will be written to the file, the file will contain no image data. If set to false, broken frames will be skipped. |
| JPEGQuality | false | false | Scalar | READ_WRITE | Tango::DEV_SHORT | OPERATOR | jpeg quality (0 - 100) |
| CrossWire | false | false | Scalar | READ_WRITE | Tango::DEV_BOOLEAN | OPERATOR | If set to true, insert crosswire into image |
| CrossWidth | false | false | Scalar | READ_WRITE | Tango::DEV_LONG | OPERATOR | Width of crosswire in pixels |
| CrossY | false | false | Scalar | READ_WRITE | Tango::DEV_LONG | OPERATOR | Y Position of crosswire center (0 is middle of image) |
| CrossHeight | false | false | Scalar | READ_WRITE | Tango::DEV_LONG | OPERATOR | Height of crosswire in pixels |
| CrossX | false | false | Scalar | READ_WRITE | Tango::DEV_LONG | OPERATOR | X position of crosswire center (0 is middle of image) |
| CameraGone | false | false | Scalar | READ_WRITE | Tango::DEV_BOOLEAN | EXPERT | Never write to this, for internal use only !!! |
| CrossBrightness | false | false | Scalar | READ_WRITE | Tango::DEV_DOUBLE | OPERATOR | Crosswire brightness (in %, 0 = dark, 100 = white). If set to -1, the pixel values will be inverted at crosswire pixels. |
| PushChangeEvent | false | false | Scalar | READ_WRITE | Tango::DEV_BOOLEAN | OPERATOR | If set to false, the server will not push change events for the Image.. attributes. This might make sense if there are no clients in use that subscribe to Image.. attributes and you want to save on cpu time. |
| Image8 | false | false | Image | READ | Tango::DEV_UCHAR | OPERATOR | Array of unsigned char representing the acquired image(s). Pixel data are converted to 8-bit greyscale. Attribute is written if ViewingMode is set to 1. |
| Image16 | false | false | Image | READ | Tango::DEV_USHORT | OPERATOR | Array of unsigned short representing the acquired image(s). Pixel data will be converted to 16-bit greyscale. Attribute is written if ViewingMode is set to 2. |
| ImageRaw | false | false | Image | READ | Tango::DEV_UCHAR | OPERATOR | Array of unsigned char representing the acquired raw image date. ImageRaw dimensions will always be ImageSize (in bytes) x 1) Attribute is written if ViewingMode is set to 3. |
| ImageRGB | false | false | Image | READ | Tango::DEV_ULONG | OPERATOR | Array of unsigned int representing the acquired image(s) in RGB format. Pixel data will be converted to 32-bit RGB Attribute is written if ViewingMode is set to 5. |
