Printing Images

 

Print Screen Control

 


To print an image on the printer, use the P (p) key on the keyboard, or the Print Screen button on the key board.Or hit the S key on the keyboard to capture the main application window.It is important that you click the mouse first on the frame that you want to print.This includes image frames on pop ups.Clicking the mouse insures that the window in the frame has keyboard focus.The P or Print Screen key will then copy the image area of the window.The Print Screen Key might do other things, so the P key is better to use.The S or s key will capture the main application window only if the user interface and images are all 24 bit true color.This is a what you see is what you get function.The resolution and image size is that when you hit the P, Print Screen, or S key.You might want to make the frame bigger before doing so, but that will also make for a larger image file.The image file is stored in Silicon Graphics rgb format.SGI utilities, such as imgview and imgcopy can read the file produced here.However, in general this program cannot read rgb files produced by other SGI utilities because those images may be stored in a compressed format which is not used or supported by this program.The print image popup may be resized, whereas imgview will not resize an image.When printed, the image will be sized to fill up the paper. A header with the patientís name is added at the top of the page.

Comment field.

Note that a text area exist for making comments on the image.The comments will be printed at the top of the page below the header and above the image.On the popup note that the comment area and image display area are separated by a paned window.You can change the proportion in addition to resizing the window.However, the resolution of the image is limited by the size of the window that the image was copied from.

 

Scaling the image.

The default is to scale the image to fit the page.The top of the page will contain a header with the current date and time stamp, the patientís name, and other information.Below that follows the comment text.If enough is left of the first page the image will be placed on the same page.By unselecting the ďFit to PaperĒ button, the user can specify the magnification of the image.For planar images, such as a CT or MRI slice, the choice is to type in the magnification factor with 1.0 being life size, 0.50 being half life size.For projected images, the image size is specified in terms of the source to detector distance.Choosing a shorter distance will result in a smaller image, a larger distance a larger image.For 3d solid model views, the source is the eye location and the image plane can be thought of as the window being viewed.For radiographs, the source detector distance determines the image size.If the type of image cannot be determined, than the default is to specify the magnification relative to the original size of the image.This default would be taken if the source to film distance were not known for a radiograph, for example.The image size on the paper is shown for the selected magnification.Otherwise the program will size the image to fit.If the user is specifying the magnification and the image will not fit on one page, then multiple pages are used with the image split between the pages.For capture of the application window, there is only the option of fitting to the paper automatically.

Clipping the image.

You can select an area of the image to be printed.With the mouse click on a corner of the area you are interested in and drag to an opposite corner. A box will be drawn as you drag.Hitting the Clip Image button will display only the area inside the box.Only that area will print.Hitting the Restore Image button will put back the entire image.

Removing background black.

Pushing the remove black button will remove black for all black areas that touch a border of the image, and replace with white.Areas inside an image, such as lung in a CT scan will not be affected.A black border is left touching all non-black areas. This feature is strictly for saving ink with ink jet printers.You can deselect this feature and return to the original image.What is seen on the screen is what will be printed.

Rotate Image To Fit

This toggle button (select in) will allow the program to rotate the image sideways on the paper if it would fit better there (wider than high image). However, if you only view the resulting PDF file (below) you might not want images rotated.By default rotation is off.

Post Script printers.

This program only supports Post Script printers, but as a alternative below, GhostScript can be called automatically to convert a Post Script file to a PDF, where the PDF may be used as a pre-print preview and for entering a print job into the computer operating systemís printing system (Windows).The page will be formatted in Post Script.If you have more than one printer, than it is possible to choose which printer to print to.The program resource files must have been set up to include the printer queues available.Select Printer under the Options pull down on the main menu.A tool bar is pushed that includes an option menu that you may select the printer queue name with.Once you have made a selection, any future print job will go to that queue.

Non-Post Script Printers

Use Gsview or the Adobe Reader (Evince on linux) as a print preview and print from the viewer (see Print Preview below).

PDF file viewer

You may choose to convert your print jobs to PDF format.In this case GhostScript will be called to convert the Post Script file to PDF format and a PDF viewer will be called to display the resulting PDF file.Set the print que name to UseAdobe.May 2012 change: Once the pdf file is successfully created, the Post Scrip file will be deleted.

Print Preview

You may choose to use Gsview as a print preview, or a PDF reader.Set the print que name to gsview or UseAdobe respectively.In either case, you can print from the viewer to non-Post Script printers.On Linux a pdf viewer must be available.On Windows, the default PDF viewer will be called.

Print Button

Hitting the print button will send the print job immediately to a printer or printer system.A Post Script file is written out in the temporary directory (see below next item).

Add to Print Queue

Hitting this button will queue up print jobs within the program in a single Post Script file.By default the file is in the temporary directory located by the tmp.dir.loc file in the program resources directory (located by the rlresources.dir.loc file in the current directory).However this has been changed as indicated below.

 

PatientReports.loc file

June 2012 change:A file called PatientReports.loc in the program resources directory will specify where patient reports are to go.The file has the format:

 

/* file format version */ 1

//reports go to patient folder, put1

//reports go to the below directory, put 2(next line)

/* 1 or 2 */†††† 1

// alternate location if above is 2

<*c:/home/Reports.d*>

 

If a patient has been selected and the reports are to go to the patient directory, then the files will be created under the patient directory in a sub-folder called Reports, followed by a folder made of the current date that the print file is created.For RtDosePlan and DosimetryCheck, printing called from a plan that is specific to the plan will be in a further sub-folder made from the name of plan.Nothing will be printed until Print Queued Jobs is selected.The pages will be numbered consecutively.Other print functions may or may not offer the option of adding to the queued Post Script file.

 

If to some other location, a subfolder will be made of the patientís name in the patient directory, followed by a sub-directory made of the date.

 

Print Queued Jobs

Hitting this button will submit the accumulated Post Script file for printing.There is also access to printing the queue from the Printer Toolbar shown below and other applications may provide other access to printing the queued job.If you exit the program with an open non-empty queue, you will be given the option of printing before the program exits.

Delete Queued Jobs

Hitting this button will complete the current open Post Script file but will not submit it to be printed.The file is in the temporary directory located by the tmp.dir.loc file in the program resources directory (located by the rlresources.dir.loc file in the current directory) or (after May 2012) will be in a subfolder of the patientís directory.

Save to file.

You may save your print screens along with your comments by hitting the Save As button on the popup.The files are saved under the directory patient name/scd.d.You may make subdirectories below scd.d to organize your print screen files.In the Get File and Directory popup, you can type in the name of a subdirectory to add below the directory currently shown.Then enter in a file name.You may want to resize this window to show all the text.Note also that you can view the complete path to a file or select to see only the current file names.You cannot navigate above the scd.d directory.

 

Get File Name and Directory Popup

 

The comments you enter are stored under the file name that you specify.The image is stored under the file name with the extension .rgb added.Unix does not have a limit to the length of file names, but certain characters are not allowed.The program will strip out illegal characters in a file name for you.If you need to reorganize or delete files, use the operating system tools provided.On SGI you have the Desktop which is graphical, or you can use the standard unix and linux commands, among them are:cd, mv, cp, rm, rmdir, ls.On Windows there is Windows Explorer and similar DOS commands.


 

Printer Toolbar

 

 

The Printer Toolbar is shown above.You can select a different printer que here.However, this will not effect an existing queued job, only new print jobs.Option to print or the delete the existing queued job is also provided here.†† This tool bar is gotten to under the Options pull down on the main toolbar.
