1 Choose File > Export > ZoomView.
2 Set the following options, and click OK:
Template Specify a template for generating the MTX, HTML, and auxiliary files. Choose a

Output Location Click Folder to specify an output location. Enter a name in the Base

Viewpoint Corporation requires that all publishers of ZoomView content acquire a
broadcast license. To apply for a key, click Get License.
Image Tile Options ZoomView technology uses image tiling to load only the part of a
high-resolution image that a user wants see. Select a Tile Size to control how many pixels
are in each tile. A tile size of 128 is recommended for small images; a tile size of 256 is
recommended for large images.
To specify an amount of compression for each tile image, choose an option from the
Quality menu, drag the Quality pop-up slider, or enter a value between 0 and 13 in the
Quality text box. Select Optimize Tables to create enhanced JPEGs with slightly smaller file
sizes. This option is recommended for maximum file compression.
Browser Options Specify a width and height for the image in the Viewpoint Media
Player. Select Preview in Browser to launch your default Web browser and load the
generated HTML file after you click OK.
About file formats
Graphic file formats differ in the way they represent image data (as pixels or as vectors), in
compression technique, and in which Photoshop and ImageReady features they support.
For more information on choosing file formats when opening or saving images,
see "Opening and importing images" on page 73
For information on choosing a Web optimization format, see
page 415.
Note: If a supported file format does not appear in the appropriate dialog box or
submenu, you may need to install the format's plug-in module. (See
modules" on page 58.)
About file compression
Many file formats use compression to reduce the file size of bitmap images.
Lossless techniques compress the file without removing image detail or color information;
lossy techniques remove detail. The following are commonly used compression
techniques:
RLE (Run Length Encoding) Lossless compression; supported by some common
Windows file formats.
