Summary
Returns all Net objects whose Color property complies with the Query.
Syntax
Color : Numeric_String
Color : Number
The color corresponding to a particular number can be deduced from the following relationship:
65536 * Blue + 256 * Green + Red
where the Blue, Green, and Red components each have a value between 0 and 255 (inclusive).
When the Color keyword can be used in conjunction with a Number, it is possible to individually evaluate the values of each of the Color property's Blue, Green, and Red components, by using the following constructs:
- Blue = Color Div 65536
- Green = Color Div 256 Mod 256
- Red = Color Mod 256
Example Usage
Color = '0'
Color <> '' && Color = 0
Returns all Net objects whose Color property is 0 (which corresponds to values of Blue = 0, Green = 0, and Red = 0).
Color = '16711680'
Color > '' && Color = 16711680
Returns all Net objects whose Color property is 16711680 (which corresponds to values of Blue = 255, Green = 0, and Red = 0).
Color <> '16777215'
Returns all objects except Net objects whose Color property is 16777215 (which corresponds to values of Blue = 255, Green = 255, and Red = 255).
ObjectKind = 'Net' && Color <> 16777215
Returns all Net objects whose Color property is not 16777215.
IsNet && Color Div 65536 >= 96 && Color Div 256 Mod 256 Between 64 And 192 && Color Mod 256 <= 128
Returns all Net objects whose Color property is such that the Blue component has a value which is greater than or equal to 96, the Green component has a value which is greater than or equal to 64 and less than or equal to 192, and the Red component has a value which is less than or equal to 128.
IsNet && Color Div 65536 <= 192
Returns all Net objects whose Color property's Blue component has a value which is less than or equal to 192.
IsNet && Color Mod 256 Between 64 And 192
Returns all Net objects whose Color property's Red component has a value which is greater than or equal to 64 and less than or equal to 192.
Tips
- The Color property is only defined for Net objects.
- The child objects of Net objects returned by the Query, are not returned.
