Class Hierarchy

Base classes

QgsRasterRenderer	Raster renderer pipe that applies colors to a raster.
QgsRasterInterface	Base class for processing filters like renderers, reprojector, resampler etc.

Methods

band	Returns the band used by the renderer
classificationMax
classificationMin
constShader	Returns the raster shader
createShader	Creates a color ramp shader
setBand	Sets the band used by the renderer.
setClassificationMax
setClassificationMin
setShader	Takes ownership of the shader
shader	Returns the raster shader

Static Methods

create

class qgis.core.QgsSingleBandPseudoColorRenderer

Bases: QgsRasterRenderer

__init__(input: QgsRasterInterface | None, band: int = -1, shader: QgsRasterShader | None = None)

Note: takes ownership of QgsRasterShader

Parameters:

• input (Optional[QgsRasterInterface])

• band (int = -1)

• shader (Optional[QgsRasterShader] = None)

band(self) → int

Returns the band used by the renderer

Deprecated since version 3.38: Use inputBand() instead.

Return type:

int

classificationMax(self) → float

Return type:

float

classificationMin(self) → float

Return type:

float

constShader(self) → QgsRasterShader | None

Returns the raster shader

Return type:

Optional[QgsRasterShader]

static create(elem: QDomElement, input: QgsRasterInterface | None) → QgsRasterRenderer | None

Parameters:

• elem (QDomElement)

• input (Optional[QgsRasterInterface])

Return type:

Optional[QgsRasterRenderer]

createShader(self, colorRamp: QgsColorRamp | None = None, colorRampType: Qgis.ShaderInterpolationMethod = Qgis.ShaderInterpolationMethod.Linear, classificationMode: Qgis.ShaderClassificationMethod = Qgis.ShaderClassificationMethod.Continuous, classes: int = 0, clip: bool = False, extent: QgsRectangle = QgsRectangle())

Creates a color ramp shader

Parameters:

• colorRamp (Optional[QgsColorRamp] = None) – vector color ramp. Ownership is transferred to the shader.

• colorRampType (Qgis.ShaderInterpolationMethod = Qgis.ShaderInterpolationMethod.Linear) – type of color ramp shader

• classificationMode (Qgis.ShaderClassificationMethod = Qgis.ShaderClassificationMethod.Continuous) – classification mode

• classes (int = 0) – number of classes

• clip (bool = False) – clip out of range values

• extent (QgsRectangle = QgsRectangle()) – extent used in classification (only used in quantile mode)

setBand(self, bandNo: int)

Sets the band used by the renderer.

setClassificationMax(self, max: float)

Parameters:

max (float)

setClassificationMin(self, min: float)

Parameters:

min (float)

setShader(self, shader: QgsRasterShader | None)

Takes ownership of the shader

Parameters:
