Class: QgsProcessingParameterRasterDestination¶

class qgis.core.QgsProcessingParameterRasterDestination¶

Bases: qgis._core.QgsProcessingDestinationParameter

A raster layer destination parameter, for specifying the destination path for a raster layer created by the algorithm.

New in version 3.0: Methods

`algorithm`	Returns a pointer to the algorithm which owns this parameter.
`asScriptCode`	Returns the parameter definition encoded in a string which can be used within a Python processing script.
`checkValueIsAcceptable`
`clone`
`createByDefault`	Returns true if the destination should be created by default.
`defaultFileExtension`
`defaultValue`	Returns the default value for the parameter.
`dependsOnOtherParameters`	Returns a list of other parameter names on which this parameter is dependent (e.g.
`description`	Returns the description for the parameter.
`dynamicLayerParameterName`	Returns the name of the parameter for a layer linked to a dynamic parameter, or an empty string if this is not set.
`dynamicPropertyDefinition`	Returns the property definition for dynamic properties.
`flags`	Returns any flags associated with the parameter.
`fromScriptCode`	Creates a new parameter using the definition from a script code.
`fromVariantMap`
`generateTemporaryDestination`	Generates a temporary destination value for this parameter.
`isDestination`
`isDynamic`	Returns true if the parameter supports is dynamic, and can support data-defined values (i.e.
`metadata`	Returns the parameter’s freeform metadata.
`name`	Returns the name of the parameter.
`provider`	Returns a pointer to the provider for the algorithm which owns this parameter.
`setCreateByDefault`	Sets whether the destination should be created by default.
`setDefaultValue`	Sets the default `value` for the parameter.
`setDescription`	Sets the `description` for the parameter.
`setDynamicLayerParameterName`	Sets the `name` for the parameter for a layer linked to a dynamic parameter, or an empty string if this is not set.
`setDynamicPropertyDefinition`	Sets the property `definition` for dynamic properties.
`setFlags`	Sets the `flags` associated with the parameter.
`setIsDynamic`	Sets whether the parameter is `dynamic`, and can support data-defined values (i.e.
`setMetadata`	Sets the parameter’s freeform `metadata`.
`setName`	Sets the `name` of the parameter.
`setSupportsNonFileBasedOutputs`	Sets whether the destination parameter supports non filed-based outputs, such as memory layers or direct database outputs.
`supportsNonFileBasedOutputs`	Returns true if the destination parameter supports non filed-based outputs, such as memory layers or direct database outputs.
`toOutputDefinition`
`toVariantMap`
`toolTip`	Returns a formatted tooltip for use with the parameter, which gives helpful information like parameter description, ID, and extra content like default values (depending on parameter type).
`type`
`typeName`	Returns the type name for the parameter class.
`valueAsPythonString`
