Redundant keyword 'mutable' removed in CDL files. In IGESConvGeom_GeomBuilder, unused methods MakeXY() and MakeXYZ() removed. Method StepAP214_AutoDesignGroupAssignment::Init() replicating same method of the base class is removed as it causes CDL extraction error after above (seemingly irrelevant) changes.

class Color from IGESGraph inherits ColorEntity
|
|
|
|
---Purpose : defines IGESColor, Type <314> Form <0>
|
|
-- in package IGESGraph
|
|
--
|
|
-- The Color Definition Entity is used to communicate the
|
|
-- relationship of primary colors to the intensity level of
|
|
-- the respective graphics devices as a percent of full
|
|
-- intensity range.

|
|
red : Real;
|
|
green : Real;
|
|
blue : Real;
|
|
aColorName : HAsciiString);
|
|
---Purpose : This method is used to set the fields of the class Color
|
|
-- - red : Red color intensity (range 0.0 to 100.0)
|
|
-- - green : Green color intensity (range 0.0 to 100.0)
|
|
-- - blue : Blue color intensity (range 0.0 to 100.0)
|
|
-- - aColorName : Name of the color (optional)
|

|
RGBIntensity (me; Red, Green, Blue : out Real);
|
|
-- returns the RGB intensities in the Red, Green, Blue
|
|
-- fields respectively
|
|
|
|
CMYIntensity (me; Cyan, Magenta, Yellow : out Real);
|
|
-- returns the CMY equivalents of RGB intensities.
|
|
--
|
|
-- The algorithm used for getting CMY from RGB is :
|
|
--
|
|
-- C = 100.0 - R where : R = red C = cyan
|
|
-- G = 100.0 - M G = green M = magenta
|
|
-- B = 100.0 - Y B = blue Y = yellow
|
|
--
|
|
|
|
HLSPercentage (me; Hue, Lightness, Saturation : out Real);
|
|
-- returns the HLS equivalents of RGB intensities.
|
|
--
|
|
-- The algorithm used for getting HLS from RGB is :
|
|
--
|
|
-- H = (1/(2*PI))*ARCTAN((2*R - G - B) / (SQUAREROOT(3)*(G - B)))
|
|
-- L = (1 / 3)*(R + G + B)
|
|
-- S = SQUAREROOT(R*R + G*G + B*B - R*G - R*B - B*G)
|
|
--
|
|
-- where H = Hue, L = Lightness, S = Saturation,
|
|
-- PI = 3.14... (constant)

HasColorName (me) returns Boolean;
|
|
---Purpose : returns True if optional character string is assigned,
|
|
-- False otherwise.
|
|
|
|
ColorName (me) returns HAsciiString from TCollection;
|
|
---Purpose : if HasColorName() is True returns the Verbal description of
|
|
-- the Color.
