Optimizing Photos and Bitmaps
With the ever increasing resolution and file size of digital camera JPEGs, if you have a document
containing many images, the file size can quickly become very large. For example, a multi-page document
containing 20 full resolution JPEGs, each of 5mb, would produce a .xar file of over 100mb*.
Furthermore, these photos are often unnecessarily high resolution. Reducing a photo from a 8 megapixel
digital camera to be 2 inches (5 cm) wide on the page will result in this image being around 1500 dpi.
Whilst a very high resolution image gives greater flexibility for printing (and you can zoom in, or enlarge
small parts of the photo), this is far higher than required for even the best quality commercial printing, and
even more so for web graphics or HTML production.
If you clip to a small part of the image, or cut-out only a small part of your photos, there could be large
parts of hidden image outside the visible area. For editing purposes this "live crop" is a great feature, as
you can un-crop, alter the size, position and scale and everything remains as sharp as possible. But for
finished documents you may want to remove the invisible parts.
The cut-out butterfly image still has the rest of the photo attached. If you go into the Fill Tool
you can easily see this by resizing the fill inside the outline. So the parts of the image outside the butterfly
will probably be superfluous in your final document.
Right click a photo and choose Optimize Photo or choose "Utilities" > "Optimize photo.."..
This dialog performs three important functions:

Removing invisible parts of photos

Reducing resolution of photos

Converting PNG or bitmaps to embedded JPEGs to optimize file size
Selecting this menu option for any bitmap will display the Optimize Photo
dialog.
