Gamma Options

Input Image

Determines whether a single frame is converted (Single Frame), or an entire animation is converted (Sequence). If Input Images is Sequence, then the From, To, and By parameters become available. The default setting is Single Frame.

Multipliers

Scaling factors applied to the RGB intensities of the image. The slider range is 0 to 100. The default value is 1 (no intensity change).

From, To, By

The first frame (From), last frame (To), and frame increment (By) of the animation to be converted. The frame number is appended to each file name. These parameters are only available if Input Image is Sequence. For example, if the From value is 1, the To value is 20, the By value is 1, and the output file name is pixfile, then the actual output file names will be pixfile.1, pixfile.2, ..., pixfile.20. The slider range is 1 to 100. The default value is 1.
