CAD to Image

The CADViewer demo demonstrates this functionality. See Samples.

The following CADRaster sample illustrates how you can create a raster page from a CAD page:

CS
VBNET

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(); }

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

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:

CS
VBNET

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); } }

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

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.
