transparencyMethod

Represents the transparency method.

Methods

alpha	Returns the alpha value in the range from 0 to 255 of the transparency object.
alphaPercent	Returns the alpha value in the range from 0.0 to 1.0 of the transparency object.
dwgIn	Reads from the specified .dwg filer data for this object.
dwgOut	Writes to the specified .dwg filer data of this object.
isByAlpha	Checks whether the transparency method is byAlpha for the transparency object and returns true if and only if the transparency method is set to kByAlpha, otherwise it returns false.
isByBlock	Checks whether the transparency method is byBlock for the transparency object and returns true if and only if the transparency method is set to kByBlock, otherwise it returns false.
isByLayer	Checks whether the transparency method is byLayer for the transparency object and returns true if and only if the transparency method is set to kByLayer, otherwise it returns false.
isClear	Checks whether the transparency method is byAlpha and the transparency is set to full for this transparency object. It returns true if and only if the transparency method is set to kByAlpha and Alpha = 0, otherwise it returns false.
isInvalid	Checks whether the transparency method is an error value for the transparency object and returns true if and only if the transparency method is set to kErrorValue, otherwise it returns false.
isSolid	Checks whether the transparency method is byAlpha and the opacity is set to full for this transparency object. It returns true if and only if the transparency method is set to kByAlpha and Alpha = 255, otherwise it returns false.
method	Returns the transparency method of the transparency object as a value of the transparencyMethod enumeration.
serializeIn	Sets the transparency method and transparency components as an integer value for the transparency object.
serializeOut	Returns the packed 32-bit integer value that stores the transparency method and transparency components.
setAlpha	Sets the alpha value and switches the transparency method to kByAlpha for the transparency object.
setAlphaPercent	Sets the alpha value as a percentage and switches the transparency method to kByAlpha for the transparency object.
setMethod	Sets the transparency method for the transparency object.

Operators

!=	Compares two transparency objects as integer values, and returns true when their values are not equal or false when their values are equal.
==	Compares two transparency objects as integer values, and returns true when their values are equal or false when their values are not equal.
