uses
Color from Quantity,
NameOfColor from Quantity,

raises
RangeError from Standard,
BadAccess from Aspect
is
Create( basepixel,dimension : in Integer from Standard ;
color : in Color from Quantity )
returns mutable ColorRampColorMap from Aspect
raises RangeError from Standard ;
---Level: Public
---Purpose : Create a Color Ramp Colormap starting from Black at
-- basepixel to color at basepixel+dimension-1.
Create( basepixel,dimension : in Integer from Standard ;
colorName : in NameOfColor from Quantity )
returns mutable ColorRampColorMap from Aspect
raises RangeError from Standard ;
---Level: Public
---Purpose : Create a Color Ramp Colormap starting from Black at
-- basepixel to color at basepixel+dimension-1.
ColorRampDefinition( me : in ;
basepixel,dimension : out Integer from Standard ;
color : out Color from Quantity ) ;
---Level: Public
---Purpose : Get Color Ramp Colormap definition .

---Purpose : Create a Color Ramp Colormap starting from Black at
-- basepixel to color at basepixel+dimension-1.
FindColorMapIndex ( me ;
ColorMapEntryIndex : Integer from Standard )
returns Integer from Standard
raises BadAccess from Aspect ;
---Level: Public
---Purpose: Returns the index in the ColorMap of the
-- ColorMapEntry.Index() equal to <AnEntryIndex>.
-- Warning: Raises BadAccess if the index is not defined in the
-- ColorMap.
FindEntry ( me ; AColorMapEntryIndex : Integer from Standard )
returns ColorMapEntry from Aspect
raises BadAccess from Aspect ;
---Level: Public
---Purpose: Returns the ColorMapEntry with ColorMapEntry.Index()
-- equal to <AnEntryIndex>.
-- Warning: Raises BadAccess if the index is not defined in the
-- ColorMap.
---C++: return const &
NearestColorMapIndex( me ; aColor : Color from Quantity )
returns Integer from Standard ;
---Level: Public
---Purpose: Returns the index in the ColorMap of the
-- nearest matching ColorMapEntry
NearestEntry( me ; aColor : Color from Quantity )
returns ColorMapEntry from Aspect ;
---Level: Public
---Purpose: Returns the nearest ColorMapEntry that match aColor .
---C++: return const &
AddEntry (me : mutable; aColor : Color from Quantity)
returns Integer from Standard;
---Level: Public
---Purpose: Search an identical color entry in the color map <me>
-- or returns the nearest ColorMapEntry Index.
