Specifications

You will first be prompted to select a file, and then this window will appear. To change your

file selection, click the "..." button. You may choose a transparent background color, and you

may set the image's Opacity (alpha blending %). The preview window has a gradient

background so that you may see how your image might appear against backgrounds of varying

intensity. If you do not choose to Constrain proportions on your image, you will be able to

size the image height apart from its width, causing it to distort from its original aspect ratio.

As with a text overlay, you may choose to make the display of a graphic overlay conditional by

specifying Required DIO input bits. The text will only be shown if all bits specified are present

on the DIO input

(See 11.) signal. You may combine bits using their power-of-two value, for

example 1 + 4 + 16 = 21 represents the combination of bits 0, 2 and 4.

To edit the properties of either a text or image object, click the object with the right mouse

button.

Effect Filters

One aspect of the power of the DirectShow architecture is apparent with the video filters

feature. You may add third-party "filters" to the video that perform a variety of special effects,

image processing, or analysis.
