class PseudoColorImage from Image inherits DIndexedImage from Image
---Purpose : A PseudoColorImage is a DIndexedImage associated with a
-- ColorMap . The ColoMap is set at Creation time and then
-- never be changed. Each Pixel in the Image ,as a IndexPixel
-- from Aspect, match a ColoMap Entry with the same value.

is
Create( x,y,dx,dy : in Integer from Standard ;
aColorMap : ColorMap from Aspect )
returns mutable PseudoColorImage from Image;
---Level: Public
---Purpose : Creates a PseudoColorImage object.
-- The default Background Pixel is set to 0 .
-- All the Image is initialised with Background Pixel
Create( x,y,dx,dy : in Integer from Standard ;
aColorMap : ColorMap from Aspect ;
BackPixel : IndexPixel from Aspect )
returns mutable PseudoColorImage from Image;
---Level: Public
---Purpose : Creates a PseudoColorImage object and set the
-- Background Pixel.
-- All the Image is initialised with Background Pixel
Type ( me : immutable ) returns TypeOfImage from Image ;
---Level: Public
---Purpose : Returns the Image Type.
ColorMap( me ) returns immutable ColorMap from Aspect;
---Level: Public
---Purpose : returns the Image ColorMap .
PixelColor( me : immutable ; X,Y : in Integer from Standard )
returns Color from Quantity ;
---C++: return const &
---Level: Public
---Purpose : Returns the Pixel Color .
RowColor ( me : immutable ; Y : in Integer from Standard )
returns HArray1OfColor from Quantity is redefined ;
---Level: Public
---Purpose : Return the PixelRow Color in a HArray1 of Color.
RowColor ( me : immutable ;
Y : in Integer from Standard ;
aArray1 : in out Array1OfColor from Quantity ) is redefined ;
---Level: Public
---Purpose : Stores the PixelRow Color in a Array1 .
Squeeze( me : immutable ;
BasePixel : IndexPixel from Aspect )
returns PseudoColorImage from Image ;
---Level: Public
---Purpose : Creates a new Image with continuous Pixel and a continuous
-- ColorMap whith only used Image color starting from
-- BasePixel .
SqueezedLookupTable(
me : immutable ;
BasePixel : IndexPixel from Aspect ;
aLookup : in out LookupTable from Image ) ;
---Level: Public
---Purpose: Creates a LookupTable that can be used to create a
-- new Image with continuous Pixel and a continuous
-- ColorMap with only used Image color starting
-- from BasePixel .
Lookup( me : mutable ;
aLookup : in LookupTable from Image ) ;
---Level: Public
---Purpose : Pass a PseudoColorImage through a lookupTable
Extrema( me : immutable ; Min, Max : in out IndexPixel from Aspect );
---Level: Public
---Purpose: Find the maximum and minimum Pixel Value of an Image.
Threshold( me : mutable ; Min, Max : IndexPixel from Aspect ;
Map : IndexPixel from Aspect );
---Level: Public
---Purpose: This method changes the value of any Pixel beetwen the
-- range (Min->Max) to the Pixel Map value. All Pixel values
-- outside the range are passed through without changed .
Rescale( me : mutable ; Scale, Offset : Real from Standard ) ;
---Level: Public
---Purpose : Map the Image Pixel Value from one range to another range.
-- This method perform the mapping by multiplying each
-- Pixel Value by Scale and then adding Offset to the result.
Dup ( me : immutable ) returns mutable Image from Image;
---Level: Public
---Purpose : Duplicate a Image.
-- ******************* Redefined method ***************************
-- ShallowCopy (me) returns mutable like me ;
---Level: Public
-- ---Purpose: Returns a copy at the first level of <me>. The objects
-- -- referenced are not copied. Entities copied by
-- -- ShallowCopy are equal.
-- ---C++: function call
-- DeepCopy (me) returns mutable like me ;
---Level: Public
-- ---Purpose: Returns a deep copy of <me>. The objects
-- -- referenced are copied. Entities copied by
-- -- DeepCopy are similar (c.f the Method IsSimilar).
-- ---C++: function call
