IColor Interface

Provides access to members that control the basic color interface.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

IColor is a generic interface that are implemented by all the other color CoClasses. IColor is also where transparency is managed. The other color interfaces derived from IColor interface are: IRgbColor, ICmykColor, IHsvColor, IHlsColor, and IGrayColor. You can also convert any of the color interfaces to OLE color objects by using the RGB method.

 

Members

Name Description
Read/write property CMYK The CMYK value of color.
Method GetCIELAB The CIELAB value of color.
Read/write property NullColor Indicates whether this color is null.
Read/write property RGB The RGB value of color.
Method SetCIELAB The CIELAB value of color.
Read/write property Transparency The Alpha Blending value. (0 for transparent, 255 for opaque).
Read/write property UseWindowsDithering Indicates if colors should be dithered to simulate colors that aren't supported by the display. This only applies on displays that have 256 or fewer colors.
