LEADTOOLS provides support for loading a vector image as a raster image. Vector formats such as DXF, DWG and SVG can be converted to a raster image through a process called rasterization.
Rasterization is the process of converting a vector image to a raster image. To determine whether a certain file on disk (or in a .NET stream) contains a vector image file rather than a regular raster image, call the RasterCodecs.GetInformation or RasterCodecs.GetInformationAsync method and check the CodecsVectorImageInfo.IsVectorFile property. Here is a code snippet:
CodecsImageInfo imageInfo = rasterCodecsInstance.GetInformation(fileName, true);
if(imageInfo.Vector.IsVectorFile)
{
// A vector image file (DXF, DWG, SVG, etc)
Console.WriteLine("Vector file");
// Your code specific to working with a vector image goes here
}
To rasterize a vector image file, set the properties of the CodecsVectorLoadOptions to the desired values, and then call the RasterCodecs.Load or RasterCodecs.LoadAsync methods.
A vector image file format usually does not have a physical size. The user can specify a viewport (physical size up to which the drawing can be rendered) ViewWidth and ViewHeight. How the drawing is to be rendered inside this viewport depends on the current viewport mode set with ViewMode. Default viewport size is 640x480 pixels.
