Remarks
PURPOSE: Provides the windowed Geographic Information System (GIS) viewer implementation for displaying map layers, basemaps, graticules, selections, and topmost graphics inside a Swing JComponent.
BEHAVIOR: Bridges core viewer logic with Swing paint, mouse, keyboard, component, and window events. Supports rendering updates, coordinate transforms between map and screen space, printing, PDF output, and bitmap export.
CONSTRAINTS: For bitmap-only output without a windowed presentation surface, use TGIS_ViewerBmp instead.
Available metadata keys:
| Metadata | Values | Default | Description |
|---|---|---|---|
| TGIS_ViewerWnd.Paint.NavigateFeedback.FullCache | TRUE FALSE | TRUE | If true then all labels, selections, and topmost layers will be visible upon scaling, dragging etc. |
| TGIS_ViewerWnd.Paint.Progressive.Transparency | 0..100 | 60 | Long-term operations will be drawn as semitransparent. |
| TGIS_ViewerWnd.Paint.Progressive.FullCache | TRUE FALSE | TRUE | If true then long-term operations will be drawn behind last cached view. |
| TGIS_ViewerWnd.Paint.LabelsOnTop | TRUE FALSE | FALSE | If true then labels are drawn on top. |
| TGIS_ViewerWnd.Paint.Topmost.LabelsOnTop | TRUE FALSE | FALSE | If true then for topmost layers labels are drawn on top. |
