Bases: QgsAbstractBrushedLineSymbolLayer

__init__(path: str | None = '')

Constructor for QgsRasterLineSymbolLayer, with the specified raster image path.

Parameters:

path (Optional[str] = '')

static create(properties: Dict[str, Any] = {}) → QgsSymbolLayer | None

Creates a new QgsRasterLineSymbolLayer, using the settings serialized in the properties map (corresponding to the output from QgsRasterLineSymbolLayer.properties() ).

Parameters:

properties (Dict[str, Any] = {})

Return type:

Optional[QgsSymbolLayer]

opacity(self) → float

Returns the line opacity.

Return type:

float

Returns:

opacity value between 0 (fully transparent) and 1 (fully opaque)

setOpacity()

path(self) → str

Returns the raster image path.

setPath()

Return type:

str

static resolvePaths(properties: Dict[str, Any], pathResolver: QgsPathResolver, saving: bool)

Turns relative paths in properties map to absolute when reading and vice versa when writing. Used internally when reading/writing symbols.

Parameters:

• properties (Dict[str, Any])

• pathResolver (QgsPathResolver)

• saving (bool)

setOpacity(self, opacity: float)

Set the line opacity.

Parameters:

opacity (float) – opacity value between 0 (fully transparent) and 1 (fully opaque)

setPath(self, path: str | None)

Set the raster image path.

Parameters:

path (Optional[str])
