Resample


Digital photo images are often large in size. If you use several photo images in a document, it will slow down the program's response. It is a good practice

to do a resample of the picture first to reduce the data size when using it in a document. A quick way to do resample is converting to Thumbnail. You can

use Resample to quickly resiz an image for email or uploading.


In PageFocus, drag to resize the image to a smaller picture won't reduce the data size as it still keeps the same number of pixels in size, just display

differently. Thus using Resize by percentage or dimension won't change the pixel size. Use Resample or Convert to Thumbnial if you want to quickly resize

an image pixel size. To see the image pixel size, double-click on an image or right-click on an image and select Properties to open the Image Properties

dialog box which will list Original size in pixels and Actual display size. To see the image's data size, select the image and click the Object/Base Properties

menu to list the Basic Object Properties.
