§ 16.58 - Truncate
| Quick Reference to Scripting Command |
| a=TRUNCATE(MODE[0-7], RED, GREEN, BLUE, ALPHA, value) |
| Items in CAPS are 0/1 or ranges with more options than just 0/1. Ranges other than 0/1 are indicated by brackets, such as [0-2]. |
Truncate produces a "posterize" effect on an image. It reduces the range of colors in the selection, and creates "average colors" in each color's place.
§ 16.58.1 - Truncate Controls
§ 16.58.1.1 - Trends
Operator dialog controls that have a Trend button next to them offer animation functionality. Trend allows you to set that variable over a set of frames. Each frame of the animation can 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. Variables that have multiple states can be set to any of a number of values in the trend. Variables that are either on or off can only have an on or off value in the trend. You will notice that the trend graphs have equidistantly spaced vertical lines. Each of these lines represents a frame in the animation. The number of frames can be altered using Sequence controls... in 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. Click here to view more information on Trends.
§ 16.58.1.2 - Levels
This is the size of the color range you want to create. A large number will allow for a large range and therefore create little noticeable difference in the image, while a small number will allow for a small range and create a significant difference. These can be chosen from the presets, or you can select "N" and choose any range from 2 up to 255.
§ 16.58.1.3 - RGBA
Red, Green, Blue, or Alpha channels can be controlled independently.
