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.
