Class: QgsProcessingParameterVectorTileWriterLayers¶
- class qgis.core.QgsProcessingParameterVectorTileWriterLayers(name: str, description: str = '')¶
Bases:
QgsProcessingParameterDefinition
Constructor for QgsProcessingParameterVectorTileWriterLayers.
QgsProcessingParameterVectorTileWriterLayers(
QgsProcessingParameterVectorTileWriterLayers
)A parameter for processing algorithms that need a list of input vector layers for writing of vector tiles - this parameter provides processing framework’s adapter for QList<QgsVectorTileWriter.Layer>.
A valid value for this parameter is a list (QVariantList), where each item is a map (QVariantMap) in this form: { ‘layer’: string or
QgsMapLayer
, // key-value pairs below are optional ‘layerName’: string, ‘filterExpression’: string, ‘minZoom’: int, ‘maxZoom’: int }Static functions
parametersAsLayers()
,variantMapAsLayer()
,layerAsVariantMap()
provide conversion between QgsVectorTileWriter.Layer representation and QVariant representation.Note
This class is not a part of public API.
New in version 3.14:
