Declaration

[HandleProcessCorruptedStateExceptions]
protected virtual void Dispose(bool A_0)

Parameters

Type	Name	Description
System.Boolean	A_0

Finalize()

Allows a ColorPt to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Declaration

protected void Finalize()

Get(Int32)

Gets the tint value at a given colorant index.

Declaration

public double Get(int colorant_index)

Parameters

Type	Name	Description
System.Int32	colorant_index	the colorant_index

Returns

Type	Description
System.Double	the tint value at the specified colorant index.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

op_Assign(ColorPt)

Assignment operator

Declaration

public ColorPt op_Assign(ColorPt r)

Parameters

Type	Name	Description
ColorPt	r	object at the right of the operator

Returns

Type	Description
ColorPt	object equals to the given object

op_Equality(ColorPt)

Equals operator

Declaration

public bool op_Equality(ColorPt other)

Parameters

Type	Name	Description
ColorPt	other	object at the right of the operator

Returns

Type	Description
System.Boolean	true if the colorant values of the objects are equal, false otherwise

Set(ColorPt)

Sets value to the given ColorPt object

Declaration

public void Set(ColorPt p)

Parameters

Type	Name	Description
ColorPt	p	given ColorPt object

Set(Double)

Sets the first value x of the ColorPt.

Declaration

public void Set(double x)

Parameters

Type	Name	Description
System.Double	x	initialized value of first color value (eg. red for rgb colorspace)

Remarks

All colorants should be in the range [0..1], so colors in the range [0..255]should be divided by 255.0 first.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

Set(Double, Double)

Sets the first two values x and y of the ColorPt.

Declaration

public void Set(double x, double y)

Parameters

Type	Name	Description
System.Double	x	initialized value of first color value (eg. red for rgb colorspace)

Sets the first three values x, y, and z of the ColorPt.

Declaration

public void Set(double x, double y, double z)

Parameters

Type	Name	Description
System.Double	x	initialized value of first color value (eg. red for rgb colorspace)
System.Double	y	initialized value of second color value (eg. green for rgb colorspace)
System.Double	z	initialized value of third color value (eg. blue for rgb colorspace)

Remarks

Set(Double, Double, Double, Double)

A utility method to set the first 4 tint values. For example, color.Set(red, green, blue) will initialize the ColorPt to given tint values.

Declaration

Set(Int32, Double)

Sets the colorant index and value.

Declaration

public void Set(int colorant_index, double colorant_value)

Parameters

Type	Name	Description
System.Int32	colorant_index	the colorant_index. For example, for a color point associated with a Gray color space the only allowed value for index is 0. For a color point associated with a CMYK color space, the color_index can range from 0 (cyan) to 4 (black).
System.Double	colorant_value	the colorant_value The new tint value.

Remarks

If a color point has more than 4 colorants, SetColorantNum(num_colorants) must be called before getting or setting tint values.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception
PDFNetException	PDFNetException the PDFNet exception

SetColorantNum(Int32)

Sets the colorant number.

Declaration

public void SetColorantNum(int num)

Parameters

Type	Name	Description
System.Int32	num	the new colorant number

Remarks

If a color point has more than 4 colorants, SetColorantNum(num_colorants) must be called before getting or setting tint values. The number of colorants depends on the associated color space. To find how many colorant are associated with a given color space use color_space.GetComponentNum().
