selected object is. The bitmap transparency size, rotation and tiling can be controlled
from the TRANSPARENCY TOOL InfoBar.

Deleting images from the Gallery
When you delete a bitmap from the page, it remains in the BITMAP GALLERY. Any unused
bitmaps will be deleted from the file when saved and re-opened. However you can force
the deletion of any bitmap by selecting it and pressing the DELETE button. If the bitmap is
used in the document, it will be replaced by the standard X bitmap.
Setting the page background to a bitmap

Select the bitmap in the gallery and click the BACKGROUND button. This reveals a menu
allowing you to choose between setting the PASTEBOARD BACKGROUND or the PAGE
BACKGROUND. When setting the pasteboard background, if the image is narrower than
the page, it’s assumed you want to have the image tiled to fill the whole browser
background. Otherwise the image is applied single tiled. You can change these settings
by right clicking on the pasteboard and looking under the Pasteboard Background sub-
menu.

You can also apply an image to the background without using this gallery – just right click
on the image and see the options in the context menu.

See Website Backgrounds (on page 337) for more information.
Save

Select the bitmap and click SAVE will save the original image. In the case of an
embedded JPEG this will save the original JPEG file. Other bitmap types are best saved
as PNG bitmap type.

Bitmap Properties

The PROPERTIES button will display information about the selected bitmap in the gallery. It
also provides a way to stop image smoothing when bitmaps are enlarged. Usually all
bitmaps are smoothed when enlarged, or zoomed into, on screen. There is a check-box
option in the Properties dialog to turn this feature off, so that individual pixels are visible
when you zoom in.

Embedded JPEG files

JPEG files are hugely compressed from their original state, being up to 10 times smaller
than the original uncompressed image. In the above example, the original
uncompressed image requires more than 7mb of memory, but as the BITMAP GALLERY
shows, this JPEG file is only 1mb. A very significant reduction. This is why JPEG images
are the standard file type for digital photography and use on the web.

When you drag and drop a JPEG file (or use the "Open" or "Import" menu options) the
JPEG (reduced in size if it was large) is stored in the document, and this is what is saved
in the .xar file when you save your document.
