setExtent(self, extent: QgsRectangle)¶

Sets the extent to use for minimum and maximum value calculation.

Parameters: extent – extent in raster layer’s CRS

Note

if a map canvas is set using setMapCanvas(), its extent will take precedence over any extent set using this method.

setFromMinMaxOrigin(self, QgsRasterMinMaxOrigin)¶: Sets the “source” of min/max values.

setMapCanvas(self, canvas: QgsMapCanvas)¶

Sets the map canvas associated with the widget. This allows the widget to retrieve the current map extent from the canvas. If a canvas is set it will take precedence over any extent set from calling setExtent().

Parameters: canvas – map canvas
