sec_interp.gui package

class sec_interp.gui.PreviewRenderer(canvas: QgsMapCanvas | None = None)[source]

Bases: object

Renders interactive preview using native PyQGIS resources.

Acts as an orchestrator for several specialized modules: - PreviewLayerFactory: Handles layer creation and symbology. - PreviewAxesManager: Handles grid lines and axes labels. - PreviewOptimizer: Handles geometric simplification (LOD). - PreviewLegendRenderer: Handles legend drawing.

__init__(canvas: QgsMapCanvas | None = None)[source]

Initialize preview renderer.

Parameters:

canvas – QgsMapCanvas instance (optional)

property active_units

Expose active units from factory for legend compatibility.

draw_legend(painter: qgis.PyQt.QtGui.QPainter, rect: qgis.PyQt.QtCore.QRectF)[source]

Draw legend on the given painter. Delegates to PreviewLegendRenderer.

export_to_image(layers: list, extent, width: int, height: int, output_path: str, dpi: int = 300, show_legend: bool = True) → bool[source]

Export preview to image file. Maintains same logic but orchestrated.

render(topo_data: ProfileData, geol_data: GeologyData | None = None, struct_data: StructureData | None = None, vert_exag: float = 1.0, dip_line_length: float | None = None, max_points: int = 1000, preserve_extent: bool = False, use_adaptive_sampling: bool = False, drillhole_data: list | None = None, interp_data: list[InterpretationPolygon] | None = None, show_legend: bool = True, **kwargs) → tuple[QgsMapCanvas | None, list][source]

Render preview with all data layers.

class sec_interp.gui.SecInterpDialog(*args: Any, **kwargs: Any)[source]

Bases: SecInterpMainWindow

Type:

QgsInterface

plugin_instance

Type:

SecInterp

messagebar

The message bar widget for notifications.

Type:

QgsMessageBar
