The Image Preferences tab of the Preferences dialog is used to set procedures for using images. This tab has two primary sections:
Image Pyramids - WMS 8.0 employs a new method for opening images that has to do with the level of detail that is available for different levels of viewing. In particular, when pyramids are built, multiple files of varying resolutions are saved by WMS so that when an area is displayed (by zooming), an appropriate resolution image is available to best represent the area. While this provides clearer displays, the process takes time. When image pyramids are not built, only one resolution image is created. Thus, while viewing an area near the original resolution, the display looks well; yet when zoomed out to a more overall extent view, the image may appear choppy or grainy.
TIFF->JPEG Conversion - In order to show multiple image types in the graphics window simultaneously, image files are automatically converted to JPEG format, by default. This process can take significant time; therefore, the option exists to not convert files. Furthermore, users can specify where the converted JPEG is saved.
