Color an element based on a tagged value

[Rudi Claes]

I'm writing a script in order to color some elements on a diagram based on the presence / contents of a tagged value. Rather straightforward stuff, but the coloring is giving me some trouble. More specifically the third parameter of SetAppearance: a call to SetAppearance 1,0,255 followed by an Update gives a nice red color and 1,0,-1 returns the default color, but what of the other basic colors (yellow, blue, green, etc)? Is this documented somewhere?

Select element
Press F4
Uncheck default color
-> the RGB values are the ones you need

Not that I know off, however if you can live with a stereotype it is very easy to change an elements appearance via tagged values using shapescripts.

Not sure if this of any help, but maybe worth a look

SetAppearance (long Scope, long Item, long Value)

Item: Long - Appearance item to modify
 
0 – Background color
1 – Font Color
2 – Border Color
3 – Border Width
Value: Long - Value to set appearance to.

Value: Long - Value to set appearance to.

in VBScript

Clng(255) for red

tried passing a RGB representation of the color CLng(255-0-0)

both works

tried passing a RGB representation of the color CLng(255-0-0)

I suspect the only reason that works is because it evaluates to 255 minus zero minus zero = 255. For an RGB representation, use red + green x 100_hex + blue x 10000_hex.

Found using the diagram legend -> Apply auto color, works just fine so don't use a script anymore as  its a lot faster on the larger diagrams.
