Method Detail

createSnapshot

public ImageRenderSettings createSnapshot()

Creates and returns a snapshot copy of this settings instance.

Returns:

snapshot copy

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

getGradationCurve

public GradationCurve getGradationCurve()

Returns the gradation curve to be applied to the image.

Returns:

gradation curve

setGradationCurve

public void setGradationCurve(GradationCurve gradationCurve)

Sets the gradation curve to be applied to the image. The gradation curve may not be null. to create an identity gradation use the default constructor GradationCurve.GradationCurve().

Parameters:

gradationCurve - the new gradation curve

isDesaturate

public boolean isDesaturate()

Returns whether the desaturation is activated

Returns:

desaturation state

setDesaturate

public void setDesaturate(boolean desaturate)

Changes whether desaturation is active or not.

Parameters:

desaturate - true for active, otherwise false

getFilterType

public FilterType getFilterType()

Returns the filter type to be applied.

Returns:

FilterType

setFilterType

public void setFilterType(FilterType filterType)

Changes the filter type to be applied. The filter type may not be null. To clear prior filter type changes, use FilterType.getDefaultFilterType() as new filter.

Parameters:

filterType -

update

public void update(String propertyName,
                   RenderSettings other,
                   Object... details)

Description copied from interface: RenderSettings

Updates this instance property specified by given property name with the value provided by the other processing setting. For each update-supported property the render settings type have to provide a unique property name.

Parameters:

propertyName - the name of the property to update. Update supported properties have unique property identifier provided by the specific render settings implementation.

other - the processing setting which provide the new property value. Therefore the other processing setting have to be of the same type as this instance.

details - (optional) if some describing details are necessary to do a specific update, the details parameter will transport this informations

setUseUpscalingFilter

public void setUseUpscalingFilter(boolean useUpscalingFilter)

Set whether to use the filter type set via setFilterType(FilterType) to up-sample (scale larger than original size) images also. If set to true the scaling filter is used to create images larger than original size resulting in a smooth appearance. If set to false, the image is up-scaled on the fly during rendering using a simple nearest-neighbor interpolation resulting in a jagged appearance but reduced rendering time and memory consumption.

Parameters:

useUpscalingFilter -

isUseUpscalingFilter

public boolean isUseUpscalingFilter()

See Also:

setUseUpscalingFilter(boolean)

setAppliesToLayer

public void setAppliesToLayer(DocumentLayer layer,
                              boolean value)

Set whether this ImageRenderSettings instance shall apply to the given document layer or not.

Parameters:

layer - the document layer.

value - true if this settings instance shall apply to the given layer

isAppliesToLayer

public boolean isAppliesToLayer(DocumentLayer layer)

Returns whether this settings instance applies to the given document layer.

Parameters:

layer - the document layer

Returns:

whether this settings instance shall apply to the layer

applyToAllLayers

public void applyToAllLayers()

Sets this settings instance to apply to all document layers.
