<h2>5.4 Image objects</h2>
Images are inserted using the <em>Insert image</em> function in the
<em>File</em> menu. Once in a drawing, you can scale, stretch, and
rotate an image. You can read in some scanned drawing and draw on top
of it within Ipe. This is useful if you have a drawing on paper and
want to make an Ipe version of it.
<p>Note that there are two separate functions for inserting JPEG images
and inserting "other" images. JPEG images are literally included in
the PDF output (using PDF's <code>DCTDecode</code> filter). "Other"
images are stored as a pixel array, using Flate compression. Note
that on some systems the function for "other" images will also
accept JPEG files--obviously, the resulting PDF files will be (much)
larger than if they had been included as JPEG images.
<p>Images are stored most efficiently in PDF format. It is reasonable to
create PDF presentations with lots of JPEG photographs in Ipe. Saving
in Postscript is somewhat less efficient, as Ipe generates clean 7-bit
Postscript files.
<p>Note that images often appear on the screen with reduced resolution to
ensure fast display updates--they are saved with full quality in the
PDF/Postscript output. You can adjust the quality of the screen
preview in the <em>Preferences</em>.
