General

The Look and Feel settings affect the visual appearance of the MaxIm DL application.

When Show Image Tabs is checked, MaxIm DL reserves a small horizontal band near the top of the application window in which to display "tabs" similar to those on file folders, one for each open image window. Clicking on one of these tabs transfers application focus to the corresponding image window, and is a convenient alternative to picking the window from the list in the Window menu. When there is not enough space to present tabs for all open image windows at once, a pair of horizontal scroll arrows at the right end of the tab bar are enabled; these scroll the tabs horizontally to allow access to those that are not currently visible.

Use Dark Mode enables/disables the Dark Mode view mode.  Dark mode is useful during night operations as it reduces glare from the screen, helping to reduce impact on night vision. On the other hand the conventional bright display mode may be useful in bright lighting conditions.  Changing this switch requires restarting MaxIm DL in order to ensure all necessary bitmap resources are loaded.  Please note that some dialog boxes provided by Windows are controlled by the operating system theme.  To adjust those dialog boxes, right-click on the Windows Desktop, select Personalization, Choose your mode, and select Dark or Light

Default Zoom determines the zoom level for all new images when they are opened.

Quick Color On sets the default Quick Color RAW setting for new image windows. When enabled, Bayer-encoded RAW images are automatically displayed in full color; however the image is still stored in RAW format. Please note that Convert Color must be set up correctly before this feature will work correctly.

Crosshairs On sets the default Crosshair setting. When set, all new windows will appear with the crosshair visible.

The Fast Histogram setting, when enabled, causes MaxIm DL to skip some image pixels when developing the histogram for the Screen Stretch Panel. This greatly speeds the histogram calculation, but reduces its accuracy somewhat. Using this will improve program responsiveness for large image files.

When Enable Undo is checked, MaxIm DL creates an internal copy of an image immediately before a processing operation changes the image.  This occurs when OK or Preview is clicked. This "checkpoint" is retained only until the next operation is performed, when it is discarded and replaced by a copy of the image in its new state. MaxIm DL can provide the ability to Undo the previous operation only if the copy was made.  If you have limited memory and large images, performance may be improved by disabling the Undo feature. 

The Start-up Options control how MaxIm DL behaves with respect to any attached hardware when launched. Normally neither the Camera Control nor the Observatory Window is displayed until expressly requested by the user.

After changing any control on this tab, you must click Save (near the top of the window) to cause the change to take effect.
