10.4.1 ASPECT

display is to fill the whole display window. The effect of this is to distort the original image. Image
shape can be restored but it is first necessary to reduce the size of the display window using the
standard Windows
TM
utility (in the top right hand corner of the display window).
After window size reduction select: View
Aspect
Note that when loading images captured using other Moor LDI packages (e.g. BDA) it may not be
possible to maintain the correct aspect ratio for the video image.
