It provides various TV, SURFACE, CONTOUR, and SHADE_SURF 2D plot features on any 2D slice out of the 3D data array. It also provides the feature of dynamical sum of all the spectrum for any desired selection of the 2D slice.
The access of various 1D/2D programs such as scan2d_roi, pick1d, calibration, plot2d, plot1d, ez_fit are automated with the selected 1D/2D data array. To obtain the PS plot or generate the ASCII report is only few clicks away.
source /usr/local/rsi/idl_5.4/bin/idl_setupIn order to access IDL programs installed in the local epics/extensions/bin, a user has to make sure that the following two environment variables are set before invoking IDL :
setenv EPICS_EXTENSIONS /usr/local/epics/extensions setenv IDL_STARTUP $EPICS_EXTENSIONS/bin/$HOST_ARCH/viewer_startup.proand make sure the directory /usr/local/epics/extensions/bin/$HOST_ARCH is in his/her IDL search path.
pick3dThis UNIX script will automatically load the pick3d.pro, and all other IDL programs called by the PICK3D into the IDL session.
The buttons labeled with the suffix ... indicates there is a window or widgets associated with it.

Done - Close and exit the PICK3D program.
For picked slice # and rank, the chosen display option implies:
Display Option - Pick display option of PLOT2D,ASCII2D,ROI2D,PICK1D (default PLOT2D)
Pick Rank Option - Pick axial rank of the 3D data array (default X Axis)
Slice # List - Select axial slice # from the 3D data array (default 0)
Accept - Accept display, rank and slice # and display accordingly
View3d_2d Sum Slices... - Run VIEW3D_2DSUM slicer program with picked axial rank
Close - Close the VIEW3D_2D slicer program
PLOT2D - the PLOT2D program will be called for the selected 2D image. ASCII2D - the 2D ASCII routine will be called for the selected 2D image. ROI2D - the SCAN2D_ROI program will be called for the selected 2D image. PICK1D - the CALIBRA_PICK1D program will be called for the selected 2D image.
The 'View3d_2d Sum Slices...' button calls the VIEW3D_2DSUM program which
allows the user to examine and sum 2D image on any range of interested slices
for a specified rank.
VIEW3D_2DSUM is a widget application which allows the user flexibility to access any 2D ROI data out of a 3D array.
Please refer User's Reference Guide for view3d_2dsum for command syntax.
The drawing area plots the axial variation of the spectrum for a given set of I index and J index. The Rank represents the axial rank picked ( 0 - X axis, 1 - Yaxis, 2 - Zaxis). The I,J index represents a point from the 2D cross section. The two verical sliders allows the user to select any points from the 2D cross section. The two horizontal slider bars define the range of axial ROI (region of interest) will be used.
The two vertical lines in the drawing area reflects the range of ROI. Default is whole range. Inaddition to the two horizontal slider bars, the mouse button can also be used to define the axial ROI. The left mouse button re-position the start range, the right mouse button re-position the end range. The plot title and labels reflect the values of set variables.
The PLOT2D / ASCII2D / ROI2D / PICK2D button accepts the indices start K1 and end K2 as shown in the drawing area and sum the spectrum and generate a new cross sectional 2D image array, then calling the corresponding IDL programs with the resultant 2D image.
Slider I index - I index (default center point)
Slider J index - J index (default center point)
Slider Start index - K1 start ROI index (default 0)
Slider EndI index - K2 end ROI index (default last)
Picked Axial Rank #- Rank (defalut 0)
PLOT2D - Sum 2D ROI and run PLOT2D program
ASCII2D - Sum 2D ROI and generate ASCII2D report
ROI2D - Sum 2D ROI and run SCAN2D_ROI program
PICK1D - Sum 2D ROI and run CALIBRATION_FACTOR program
Screen Data - Show the spectrum of plot data in a TERM window
PS Plot - Send the drawing area plot to a PS divice
Done - Close and exit the VIEW3D_2DSUM program
2D_MENU is a 2D scan image selection menu to access any 2D image data out from a 2D scan array. It consists of three selection items: PanImage..., Pick2D..., and CALIB2D....
PanImages... - run PANIMAGE_SEL program
Pick 2D... - run PICK2D program
CALIB2D... - run CALIBRATION_FACTOR program
The PANIMAGE_SEL dialog gives a set of selection options to let the user dynamically reconfigure the panimage window according his preference. The default grid image size is 60x60 pixels.
The user interface of PANIMAGE_SEL is given below:
Select Sublist - Droplist to select panImage sublist from D01-D10, ...,D61-D70, D1-DF strips
Grid Exp Factor - Image grid expansion factor, default to 1.
Select Detectors - Multiple selection box of 85 detectors LMB single selection Cntl-LMB multiple selection Shift-LMB range of multiple selection
Accept Button - Accept selections and pops up panimage window
All Button - Up to last detectors defined
Print Button - Dump panImage window to PS printer
Close Button - Close this dialog
Save PanImage - Check/Uncheck save panImage option
Save Type - Save image type as TIFF/PNG/PICT/XDR
Reverse Toggle - Check/Uncheck reverse TIFF image
Save Filename - Override output save file name
The PICK2D dialog let the user select any detector image from the input 2D data array. It allows the user easily to access the 2D plot, ascii, or calibration functions.
The user interface of PICK2D is given below:
Detector List - Select the desired detector from the list
PLOT2D - Run PLOT2D program with the selected 2D image
ASCII2D - Run xdisplayfile to display 2D ascii data
CALIB2D... - Run CALIBRATION_FACTOR with input 2D data array
Done - Close the dialog
The CALIBRATION_FACTOR program let the user define the coefficient factors and dynamically define the mathematical calibration function as any combination terms of the coefficient and detector images. The multiplication factors can be modified and saved in a coefficient file. And this coefficient file can be loaded into the CALIBRATION_FACTOR program. A user can easily generate new calibration result and display the result by PLOT2D program. The other 2D image processing programs: ASCII2D, ROI, PICK1D, EZ_FIT on the calbration array are also at the user finger tip.
