Brightness

Quick Reference to Scripting Command
a=BRIGHT(percentage)
Items in CAPS are 0/1 switches or switches with more options than 0/1.

The Brightness operation alters the brightness value for each pixel in the selected area. WinImages F/x calculates brightness based on a linear measure of how far from a brightness value of zero each pixel is. The larger the value the brighter the value. Brightness values can range from -100 (minimum brightness) to 100 (maximum brightness).

Trends

Some of the controls have a Trend button next to them. These trend buttons allow you to set variables over a series of frames. Each frame of any animation may be thought of as a slice of time. The trends allow you to alter some, all, or none of the variables for a particular time slice. Trend graphs have equidistantly spaced vertical lines. For animations under 100 frames in length, each of these lines represents a frame in the animation. The number of frames in any one sequence can be altered using the Sequence controls item from the Timeline pull down menu. Animation lengths of 100 - 999 frames will be represented with a vertical bar being 10 frames, and animation length greater than 1000 frames will have a vertical bar for every 100 frames.

Brightness

The brightness settings can be altered by using the slide gadget, or by clicking on the text entry field and entering the appropriate value. The brightness operation defaults to 100 which is the maximum brightness change. The brightness can range from -100 to 100. Setting the brightness to 0 will cause no change to the image.
