Custom Size

The Custom Size field allows you to set widths and height different from the standard preset values of full, 1/2, 3/8, and 1/4.

There is a checkbox marked Fixed Ratio. If this box is checked, when you enter a size in the height box, the width is automatically adjusted to maintain the normal screen proportions; and vice versa. If this box is unchecked, the height and width may be entered independently. If the dimensions are different from normal screen proportions, the image will be stretched horizontally or vertically.

The Osprey video hardware is not capable of drawing all possible widths. Depending on the color mode selected, it may require a width that is an even number of pixels, or (for YVU9 and YVU12) a width that is a multiple of 16. The dialog will let you enter numbers that the hardware cannot utilize, but will adjust them as soon as you click on another field or button of the dialog.
