Class: 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.

Added in version 3.14.
