C# API for Rendering Map to BMP Format
We will use the Aspose.GIS for .NET API to render maps to BMP format. It is an API that supports working with geospatial data stored in various file formats. It also provides the ability to render maps and create, read, and convert geographic data without any additional software. You can either install the API through NuGet or download it directly from the Downloads section.
PM> Install-Package Aspose.GISRender Map to BMP Format using C#
The following are the steps to render maps to BMP format.
- Create an instance of the Map class.
- Create a vector layer from the shapefile and add it to the map.
- Render the map as a BMP using the Map.Render(string outputPath, Renderer renderer) method.
The following sample code shows how to render a map to BMP format using C#.
Rendering Map to Specific Projection using C#
The following are the steps to render a map to a specific projection.
- Create an instance of the Map class.
- Create a vector layer from the shapefile and add it to the map.
- Set the map’s spatial reference system using the Map.SpatialReferenceSystem property.
- Save the map as a BMP image using the Map.Render(string outputPath, Renderer renderer) method.
The following sample code shows how to render a map to a specific projection using C#.
Add Marker with Custom Style using C#
The following are the steps to add a marker with custom style to a map.
- Create an instance of the Map class.
- Create an instance of the SimpleMarker class.
- Set the properties of the SimpleMarker object according to your requirements.
- Create a vector layer from the geojson file and add it to the map along with the markers.
- Save the map as a BMP image using the Map.Render(string outputPath, Renderer renderer) method.
The following sample code shows how to add a custom-style marker to a map using C#.
