Draw Pixel with ArcGIS in C# WPF

EzraSidran — Mon, 08 Oct 2012 18:01:39 GMT

I need a function:

DrawPixel(x,y, RGB)

that simply draws a pixel of a specified RGB value on the screen at an x,y location. Apparently this is impossible in WPF, however this is do-able via ArcGIS.

The client that I'm working for uses ArcGIS and, apparently, somewhere in there is a function that will let me do this.

Can somebody please point me in the right direction?

Thanks.

Hi,

To add a temporary point to the map you should use the GraphicsLayer class: http://resources.arcgis.com/en/help/runtime-wpf/apiref/index.html?ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.Graphic.html.

When you say X,Y coordinates, if you mean screen coordinates you can use the Map.ScreenToMap method to convert: http://resources.arcgis.com/en/help/runtime-wpf/apiref/ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.Map~ScreenToMap.html.

The map coordinates should be in the same coordinate system as the map but the map will reproject them if it needs to.

Cheers

Mike
