Sharpen an image

Sharpening increases the contrast around the edges of objects to increase the image’s definition.

Note: Changing an image this way affects only this instance of the image; it does not affect the original image source file.

  1. In your draft, select the image you want to adjust.

  2. Do one of the following:

    • Click the Sharpen button icon of the button to open the sharpen dialog box. in the image editing toolbar.

    • Select Format > Edit Image > Sharpen.

    • Right-click (Windows) or Control-click (Mac OS) the image, and then select Edit Image > Sharpen.

    Note: These options are not available if you belong to a user role that the Contribute administrator has restricted from inline image editing. For more information, talk to your Contribute administrator or see Set page-editing and paragraph settings.

    The Sharpen dialog box appears.

  3. Specify the degree of sharpening by dragging the slider control, or entering a value between 0 and 10 in the text box.

    As you adjust the sharpness of the image, you can preview the change to the image.

  4. Click OK.
