| May 11, 2022 at 9:54 | comment | added | Paul | This did the trick! degrees = (mapRectangle.getMaxX() - mapRectangle.getMinX()); Map hints = new HashMap(); hints.put("dps", 96); double scale = RendererUtilities.calculateOGCScale(mapRectangle, canvasWidth, hints); | |
| May 11, 2022 at 8:33 | comment | added | Paul | degrees = (mapRectangle.getMaxX() - mapRectangle.getMinX()); int screenWidthInPix = mapFrame.getMapPane().getBounds().width; scale = (double) screenWidthInpix/degrees; // where shall I use pixel size?? | |

| May 11, 2022 at 7:39 | comment | added | Ian Turton | Geotools uses the OGC scale and pixel size of 96dpi, when you are using wgs84 the scale will be in pixels per degree so there will be no metres involved | |
