Resize
Select an image item and click Resize 
in the SET tools group in the Item ribbon to access this dialog box.
After you scan an image item or acquire a digital image, it might be necessary to change the image’s original resolution measured in dots per inch ( dpi).
For example, assume you scanned a photograph at a high resolution, such as 300 dpi, because you wanted to print the photo on a high-quality image printer. Now, however, you want to share the photo over the Internet and display it on a web page.
In this case, you can reduce the resolution from 300 dpi to 96 dpi — a better resolution for sending as an e-mail attachment and for displaying on a web site.
Use the Resize dialog box to change the current size, or physical dimensions, in addition to the current resolution.
-
Select Change Page Size and then, in the Scale box, enter the percentage to increase or decrease the item, based on the original size.
-
Select Change Resolution, and then enter the number of pixels per inch or per centimeter, and the unit of measure. The default unit is pixels/inch.
Note
High resolution settings create larger files that occupy more disk space on your computer. For images you will send to an inkjet printer, a resolution setting of 150 pixels per inch or dpi is usually adequate. For images you want to display only on a computer screen, a resolution setting of 96 produces a smaller file with a resolution that is adequate for screen display.
Tip:
If you want to keep a high-resolution image for future use, duplicate the item before lowering its resolution. The program may request your confirmation to resize the item.
