The Compress Pictures dialog box is displayed, as shown in Figure WD3-3. TIP If the Format on-demand tab is not available on the ribbon, double-click the image to display the tab. 24. Check the Apply only to this picture check box. 25. Click the Email (96 ppi) radio button. Pixels per inch (ppi) is a measure of resolution, or pixel density, of the image. The greater the ppi, which is more commonly called dots per inch (dpi), the higher the resolution of the image, but the larger the fi le size. Reducing the ppi reduces the fi le size, but also can reduce the clarity of the image, so there is a trade-off between image quality and fi le size. 26. Click the OK button to close the dialog box and apply the compression setting. You may or may not notice a visual change in the image quality. 27. Use the Shape Height text box on the ribbon (Picture Tools Format on-demand tabSize group) to change the height of the image to 2″ by entering 2 in the Shape Height text box.
