New Post: Lack of performance with Markers in WPF
Hi Radioman,
I have been using your great GMap.Net for a few months now and I have a problem to submit.
Here is what i do:
I call this method only one at the beginning. So if you have any clue for me to improve the performance it would be great.
Thanks a lot by advance for your help and one again for your job.

I have been using your great GMap.Net for a few months now and I have a problem to submit.
Here is what i do:
- I display a GMapControl in my UserControl.
-
Then I draw some areas on it (using GMapPolygon).
-
When dragging my map around the areas, the drag is very slow and cade (everything is perfect when areas are not displayed)
foreach (GeoZoneEntity area in areas)
{
Color areaColor = (Color)ColorConverter.ConvertFromString(area.Color);
// define brushes
SolidColorBrush strokeBrush = new SolidColorBrush(Colors.Black);
SolidColorBrush fillBrush = new SolidColorBrush(areaColor);
// build point list ad PointLatLong
List<PointLatLng> points = new List<PointLatLng>();
foreach (GeoZonePointEntity point in area.GeoZonePoints)
{
points.Add(new PointLatLng(point.Latitude, point.Longitude));
}
GMapPolygon polygon = new GMapPolygon(points);
polygon.RegenerateShape(mapControl);
if (polygon.Shape != null && polygon.Shape is Path)
{
(polygon.Shape as Path).StrokeThickness = 0.5;
(polygon.Shape as Path).Stroke = strokeBrush;
(polygon.Shape as Path).Fill = fillBrush;
}
mapControl.Markers.Add(polygon);
}
I call this method only one at the beginning. So if you have any clue for me to improve the performance it would be great.
Thanks a lot by advance for your help and one again for your job.

New Post: Inheriting from Polygon Type
Hello;
i'm trying to define my own Polygon implementation, adding an inernal marker that will add Tool Tip functionnality, however i faced two problems:
first , the GoogleMarker with image type None do not render (value of Bitmap can not be null).
second , the marker when set with some image, do not render in it's position.

Updated Wiki: MONO support
to be able run via mono:
- add libmono-winforms2.0-cil (Mono System.Windows.Forms library (for CLI 2.0)) in package manager, this will add all the other needed dependencies
- set MONO to compilation symbols for GMap.NET.Core andGMap.NET.WindowsForms
- choose Release target, Rebuild
vuala! It works ;}

New Post: Customizing Markers to Draw Geometric Shapes
Hello every one;
After many attempts to implement some geometric shapes , i realized that the only way to keep input over them is to update Size and Offset each time before rendering them, i have been reading some discussions where it is probably not a good idea, however, the GMapMarker Class is based on some initial "fixed" Sizes and Offsets that will not change over zooming, this is why i coul not find a good way to do that.
have any one foud a good solution to draw custom , updatable shapes without setting Size and Offset in the "OnRender" Method ??

New Post: Get underlying coordinates
I am using a custom marker that displays a pie shape on the map as a decoration for other markers. I would like to know if there is currently a way to get the collection of points under this shape(in Lat/Lng) so I can create my KML for exporting the marker data.
I know KML does not currently support arc geometry so a collection of points would work fine.

New Post: How do I get gps points along the route set?
Hello guys,
I'm doing an app where I set on the map a route based on some points that user are going to insert on a textbox.
Ok, my route is fine and works great. Now I need to export a list with some position based on this same route. Something like: for each 10m on the route I generate a new point...
For example, I generate one route with 3 points and need to export that with 10 points.
Any idea?
Thanks for any anwers and sorry about my english! =P

Closed Unassigned: How can I print GMap.NET maps? [16101]
So there is GMapControl on form. I want to print map, and here is code
```
PrintDocument doc = new PrintDocument { DocumentName = "Map printing file" };
doc.PrintPage += DocOnPrintPage;
PrintDialog dialog = new PrintDialog { Document = doc };
DialogResult result = dialog.ShowDialog();
if (result == DialogResult.OK) doc.Print();
```
and
```
private void DocOnPrintPage(object sender, PrintPageEventArgs e)
{
var img = View.gmap.ToImage();
System.Drawing.Point loc = new System.Drawing.Point(0, 0);
e.Graphics.DrawImage(img, loc);
}
```
I'm using ToImage() method, but it does not work as I want (it's like PrintScreen, because there are another objects like cursor, dialogbox, etc.) Is there any workaround to implement printing without this objects?
P.S. Gmap.Net.Core and Gmap.Net.WindowForms verison is 1.7.0.0, and .Net FrameWork version is 4.0 and I cant upgrade .Net Framework version, because some of clients are using Windows XP.
P.P.S Thank you for replies
Comments: it's working! cheers ;}
