Photo Handling 373

Viewing a scaled photo at its full size

The ZOOM TO 1:1 button on the PHOTO TOOL InfoBar adjusts the zoom so that the selected
image is shown at full size, which is where each pixel of the image is mapped to each
screen pixel. This is useful if you want to edit an image that’s been scaled down on the
page, but want to see it at its full size while you work on it.

Making a photo its full size

The SCALE PHOTO TO 100% button on the PHOTO TOOL InfoBar takes the currently selected
photo and scales it to its full size on the page. So for example if the selected photo is
scaled down to 500 pixels wide, but the original imported photo was 1000 pixels wide,
the photo on the page will be scaled up to 1000 pixels wide. When the document zoom is
100%, that means that each pixel of the image is mapped to each screen pixel.

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
