## Setting the file type

You set the file type by making a selection from the File type menu. You can choose from image file types or geometry file types. Note that some areas of the Save Window become enabled for certain file types.

Choosing JPEG format files enables the Quality slider and the Progressive check box. These controls allow you to specify the desired degree of quality in the resulting JPEG images. A lower quality setting results in blockier images that fit into smaller files. The progressive setting stores the JPEG images in such a way that they progressively refine as they are downloaded and displayed by Web browsers.

Choosing TIFF format files enables the Compression type combo box. The available compression types are: None, PackBits, JPEG, and Deflate. When compression is enabled for TIFF files, they are smaller than they would be without compression.

Choosing STL or VTK file formats saves visualizations as geometry files instead of images and also enables the Binary check box. The Binary check box tells these formats to write their geometry data as binary data files instead of human-readable ASCII text files. In general, files written with the binary option are smaller and faster to load than their non-binary counterparts.
