You can create your own zooms by running this jnlp: http://rails.dev.concord.org/sds/2/offering/144/jnlp/540/view?sailotrunk.otmlurl=http://continuum.concord.org/otrunk/examples/UDL/zoom-test-small.otml&sailotrunk.hidetree=false&jnlp_properties=otrunk.view.author%253Dtrue%2526

Click on the File menu and "Save As..."
Save the file to a location you can find later.
Open the file with a text editor. If you scroll down through the file, you will find the piece of text that looks like this:

<OTZoom local_id="zoom" name="Zoom Tool">
              <transforms>
                <OTZoomTransform scale="0.5" topLeftX="30.0" topLeftY="92.0" />
                <OTZoomTransform scale="0.5" topLeftX="30.0" topLeftY="92.0" />
                <OTZoomTransform scale="0.5" topLeftX="30.0" topLeftY="93.0" />
                <OTZoomTransform scale="0.5" topLeftX="30.0" topLeftY="94.0" />
                <OTZoomTransform scale="0.5" topLeftX="30.0" topLeftY="82.0" />
                <OTZoomTransform scale="0.5" topLeftX="30.0" topLeftY="120.0" />
                <OTZoomTransform scale="0.5" topLeftX="30.0" topLeftY="100.0" />
              </transforms>
              <images>
                <OTImage imageBytes="http://continuum.concord.org/otrunk/examples/UDL/imagessmooth/slidezoom1_smooth_sm.png" />

                <OTImage imageBytes="http://continuum.concord.org/otrunk/examples/UDL/imagessmooth/slidezoom7_smooth_sm.png" />
                <OTImage imageBytes="http://continuum.concord.org/otrunk/examples/UDL/imagessmooth/slidezoom8_smooth_sm.png" />
              </images>
</OTZoom>

There is one transform between every two images. So there is one less transform than images.
The transforms indicate how to place the next image in the current image.
So in the first transform above, the second image is scaled by 0.5, and then located at (30,92) in the first image.
This is the reverse of how the actual zoom will work.

You can modify the file you saved, and then go to the file mean and do reload.

The iamgeBytes URLs can be local URLs that are relative to the saved otml file.
