# [Common]

<- Property Sheets Common setting for Loupe and source specials is in this sheet which is common in all modes.
The functions of Loupe are specified which appears when the right button of the mouse is pressed. The setting here is [Save]d to the common position for the modes in Registry.
If you press the right mouse button with CTRL key, an another Loupe appears. You can specify its setting in the area shown by the frame "Option(+CTRL)".
Size: specifies the length of one side of the loupe or the diameter of a round loupe in pixel (dot) units.
Scale: specifies the reduction ratio with the original dpi. For example, if the original dpi is displayed by the gray scale compressed to one sixth and the Scale: is set to 2, the portion expanded by three times is displayed by the loupe.
Speed: Increase this number if the loupe afterimage remains and makes viewing difficult. The lower the value would result in smoother motion.
Shape: selects the loupe shape -- square, measured square (1 unit = 4 pixel) or circle. The square shape would work faster.
Back: specifies the background color. Set default (=the color of the sheet) in general. Setting the color to white when the display is not reversed or black when reversed, then the flickering while the loupe moves would be reduced.
Edge view: Loupe will not be hidden at the edge of the screen.
-src: specifies the way to execute the editor for source specials.
-gsrc: specifies the way to execute the graphic editor for the included graphic files.
-isp: specials which are ignored by dviout even if dviout cannot understand them.
