The default display mode will be changed in our upcoming release 8.60. In the current release, if you change the display mode and exit the TiffViewer, the TiffViewer will remember the setting for net time. For example, open and image and the default view is Maximized, change the view to “Fit To Width”. Close TiffViewer. Open the TiffViewer and image will be opened in “Fit To Width” mode.
