The Preview windows are intended to control the printing and final editing of the print list. The Preview window is used to view printing on paper and save images to a pdf file, the DICOM preview is used for printing on film. To open the target window, select the File menu and the Preview item or the DICOM preview item. The settings made in one window do not affect the settings in the other one except deleting images. The print list is common for both windows, hence, the images deleted in one of the windows are deleted from the print list, and they disappear in the other window.
The DICOM preview tab is shown in Fig. 17.1.
The toolbar is located at the top (Fig. 17.2), and the bottom part shows what the printed images will look like (preview page).

one image on the screen;

Select the desired template from the drop-down list. To add a new template, click the Create template button, to delete a template, click the Delete button. Attention! Deleting a template cannot be undone.
To change a template name, enter a new name in the Template Name field.
For the Preview tab set the space between images in the Spacing (mm) field.
For the DICOM preview tab, choose the film size from the “Film size” drop-down menu. The default value is Chosen film size for printer. If this value is chosen, the size of the film will be as set for your printer. The DICOM printer settings are described in Section 17.3.2. If you choose a different value for the printing template, the size provided for by the printer settings will be ignored.
On the left-hand side of the window you see the arrangement of images on the page. To divide any cell into any number of lines and columns, left-click on that cell to select it and enter the required number of lines and columns in the left and the right fields indicated by the arrows in Fig. 17.3. Then click Split.
If the column and/or row count is greater than 1, you can merge an arbitrary number of cells. The merged cells must form a rectangle. For example, set the Row count to 3 and the Column count to 4. Next, select cells 7, 8, 11, 12. To do it, move the cursor from cell 7 to cell 12, holding the left mouse button. Next, click Merge. The four selected cells will be merged.
To split any cell into an arbitrary number of rows and columns, select this cell, enter values in the rows and columns fields and click the Split button. The cells made by splitting can only be merged with each other.
The cells created in such a way can only be merged with other cells from the same group.
To add the header and/or the footer, proceed as follows:
Check the Header box to add the header and the Footer box to add the footer. The header and the footer will be shown in the scheme representing the cell arrangement.
Specify the header/footer height in points.
Choose an image for the header/footer. To do that, click the Browse button and choose a file with jpg, jpeg, jpe or png extension in the dialog box that pops up.
To use this header/footer for all the templates without a header/footer (including the new templates by default), click the Set this header as default or Set this footer as default button in the dialog box. Then click Yes to apply or No to cancel.
To save the changes, click OK or Apply, to cancel, click Cancel.

The DICOM Viewer provides an opportunity to add reference images to the print list. You can ascribe the same reference image to all the images on the list, or a different image to each of the images on the list. To ascribe several reference images to each study added to the print list, you can create a separate list of reference images.
To add a reference image:
Choose an image from the same study that has been added to the print list. Click the arrow on the right side of the Add to print list button and select the Add as reference image item. This image will by default be ascribed to all the images from the same study included in the print list.
If you need to add a new reference image to the list or replace it with a different one, repeat the previous step. You will see a notification that a reference image has already been added. To add another reference image to the list, click the Yes button; to replace the previous reference image, click the Rewrite buton, to cancel, click the No button.
Open the Preview or DICOM Preview window. If the Show reference image tool is inactive, activate it with the left mouse button. A reduced reference image is displayed in the corner of each image. If there is more than one image on the list of reference images, the first image added to the list will be displayed.
To adjust the display of the reference image, click the arrow on the right side of the Show reference image button and select the Property... item. You can set up the following properties:
project line width (mm).
To replace the reference image attributed to a separate image, highlight it and click the arrow on the right side of the Show Reference Image button, then click the Select Reference Image... button. Choose the image you need in the dialog box and click Select. If no image has been selected, the reference image will be changed for all the images on the print list. If there are images from different studies on the print list, the reference image can be changed only for the images selected. The Select Reference Image... function is also available in the right-click menu.
To delete a reference image from the list, click the arrow on the right side of the Show Reference Image button, then click Select Reference Image... item. Choose the image you need in the dialog box and click the Delete button.
To hide/show a reference image, click the left side of the Show Reference Image button. If there are some images selected, the action will be performed only for them.
If there are images from different studies on the print list, reference images will be ascribed to them separately.
