Exporting images in ZoomView format (Photoshop)

ZoomView is a format for delivering high-resolution images over the Web. With the Viewpoint Media Player, users can zoom into or out of an image and pan the image to see its various parts.

When you export an image in ZoomView format, Photoshop creates the following files:

• An MTX file that defines the image to be displayed.
• An HTML file that loads the Viewpoint Media Player and points to the MTX file.
• A folder containing tiles that are used to display the image.
• A folder containing VBS and JavaScript scripts that are used by the HTML file.

To export an image in ZoomView format:

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 preset template from the pop-up menu, or choose Load to choose a different ZoomView Template (ZVT) file. You can download additional templates from the Viewpoint Web site.

Output Location

Click Folder to specify an output location. Enter a name in the Base Name text box to specify a common name for the files.

Path to Broadcast License File

Specify a URL for the broadcast license file. The 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.
