NeutralDensityFilter

Bases: Filter_Type

Represents the XML element NeutralDensityFilter.

An optical Filter is a device designed to selectively control the Wavelengths, color temperature, vibration direction, and/or intensity of the radiation which it transmits or reflects. This element refers to an optical Filter whose purpose is to attenuate the intensity of the transmitted Light independent of the Wavelength.

setNDType(value)

Sets the value of the NDType attribute.

This field refers to the general category of this Neutral Density Filter. Neutral Density Filters come in two general types. Those made of darkened glass that absorb light and those coated with a metal film that reflect light.

Parameters:

Name	Type	Description	Default
value	NDTYPE_Type	The value to set	required

getNDType()

Returns the value of the NDType attribute.

This field refers to the general category of this Neutral Density Filter. Neutral Density Filters come in two general types. Those made of darkened glass that absorb light and those coated with a metal film that reflect light.

Returns:

Type	Description
NDTYPE_Type	The value of the attribute

resetNDType()

Resets the NDType attribute to an unset state.

This field refers to the general category of this Neutral Density Filter. Neutral Density Filters come in two general types. Those made of darkened glass that absorb light and those coated with a metal film that reflect light.

hasNDType()

Checks whether the optional NDType attribute is present.

This field refers to the general category of this Neutral Density Filter. Neutral Density Filters come in two general types. Those made of darkened glass that absorb light and those coated with a metal film that reflect light.

Returns:

Type	Description
boolean	true if the optional attribute has been set, false otherwise

setOpticalDensity(value)

Sets the value of the OpticalDensity attribute.

This field measures the absolute value of the logarithm of base 10 of the power transmission factor. For example, an optical density of 3 means an attenuation of optical powers by the factor 10^3

Parameters:

Name	Type	Description	Default
value	float	The value to set	required

getOpticalDensity()

Returns the value of the OpticalDensity attribute.

This field measures the absolute value of the logarithm of base 10 of the power transmission factor. For example, an optical density of 3 means an attenuation of optical powers by the factor 10^3

Returns:

Type	Description
float	The value of the attribute
