Résumé
Visualize flow direction and magnitude information in your raster with vector symbols.
Discussion
For more information about how this function works, see the Vector Renderer Field raster function.
The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method.
Syntaxe
VectorFieldRenderer (raster, {is_uv_components}, {reference_system}, {mass_flow_angle_representation}, {calculation_method}, {symbology_name})
Paramètre | Explication | Type de données |
raster | The input raster. | Raster |
is_uv_components | Specifies whether the input components represent U-V, or magnitude and direction.
(La valeur par défaut est None) | Boolean |
reference_system | Specifies how the direction component is measured.
(La valeur par défaut est 2) | Integer |
mass_flow_angle_representation | Specifies the angle of mass flow.
(La valeur par défaut est From) | Integer |
calculation_method [calculation_method,...] | Specify the thinning method to be used to calculate the magnitude and direction value of a tile.
(La valeur par défaut est Vector Average) | String |
symbology_name [symbology_name,...] | Name of the symbol depicting direction and magnitude.
(La valeur par défaut est Single Arrow) | String |
Type de données | Explication |
Raster | The output raster displayed according to your rendering parameters. |
Exemple de code
