The CADViewer demo demonstrates this functionality. See Samples.
The following CADRaster sample illustrates how you can create a raster page from a CAD page:
| C# |
Copy Code |
using System.IO;
using ImageGear.Formats;
using ImageGear.Formats.CAD;
public static void CadToRaster(string path)
{
ImGearCADPage page = null;
// Load file.
using (FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read))
{
page = ImGearFileFormats.LoadPage(fileStream, 0);
}
// Get an ImGearRasterPage from the loaded ImGearCADPage
ImGearRasterPage raster = page.Rasterize();
} |
| VB.NET |
Copy Code |
Imports System.IO
Imports ImageGear.Formats
Imports ImageGear.Formats.CAD
Public Sub CadToRaster(path As String)
Dim page as ImGearCADPage
' Load file.
Using fileStream as FileStream = New FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read))
page = ImGearFileFormats.LoadPage(fileStream, 0)
End Using
' Get an ImGearRasterPage from the loaded ImGearCADPage
Dim raster as ImGearRasterPage = page.Rasterize()
End Sub |
If you simply wish to save your CAD file as an image the following sample shows how this can be done:
| C# |
Copy Code |
using System.IO;
using ImageGear.Formats;
using ImageGear.Formats.CAD;
public static void CadToImage(string inPath, string outPath)
{
ImGearCADPage page = null;
// Load file.
using (FileStream fileStream = new FileStream(inPath, FileMode.Open, FileAccess.Read, FileShare.Read))
{
page = ImGearFileFormats.LoadPage(fileStream, 0);
}
// Save a CAD file to a PNG image
ImGearSavingFormats formatOut = ImGearSavingFormats.PNG;
using (FileStream fileStream = new FileStream(outPath, FileMode.Create, FileAccess.Write, FileShare.Read))
{
ImGearFileFormats.SavePage(page, fileStream, formatOut);
}
} |
| VB.NET |
Copy Code |
Imports System.IO
Imports ImageGear.Formats
Imports ImageGear.Formats.CAD
Public Sub CadToImage(inPath As String, outPath As String)
Dim page as ImGearCADPage
' Load file.
Using fileStream as FileStream = New FileStream(inPath, FileMode.Open, FileAccess.Read, FileShare.Read))
page = ImGearFileFormats.LoadPage(fileStream, 0)
End Using
' Save a CAD file to a PNG image
Dim formatOut As ImGearSavingFormats = ImGearSavingFormats.PNG
Using fileStream as FileStream = New FileStream(outPath, FileMode.Create, FileAccess.Write, FileShare.Read))
ImGearFileFormats.SavePage(page, fileStream, formatOut)
End Using
End Sub |
Any conversions made to the CADPage’s camera will reflect in the saved image.
