Changing image resolution

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 to 96 — a better resolution for sending as an e-mail attachment and for displaying on a web site.

In the Image View window

  1. Display the image item.

  2. On the Page ribbon, choose PaperPort resize Changing image resolution Resize.

  3. In the Resize dialog box, select Change Resolution, and then enter the number of pixels per inch or per centimeter, according to the specified unit of measure

    Note that changing the pixel dimensions of an image item can result in a loss of quality and sharpness.
     

  4. Click OK.

On the PaperPort desktop

  1. Select one or more items of the same file type.

  2. On the Item ribbon, choose PaperPort resize Changing image resolution Resize.

  3. In the Resize dialog box, 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.

  4. Click OK.

Tips

For photos that will be printed on a high-quality photograph printer, set the resolution to 300 dpi. For black-and-white documents, use 300 dpi or more depending upon the job requirements — and, for images that will be printed on an inkjet printer, use 150-200 dpi for best results.

Remember that the higher the resolution, the larger the size of the image file on your computer.
