Using DXFImportNET in ASP.NET

[txia007]

Dim FCADImage As CADImage
FCADImage = New CADImage

FCADImage.Load("D:\Inetpub\wwwroot\DXF\RW030.dxf") FCADImage.SaveToFile("D:\Inetpub\wwwroot\JPG\foo.jpg",System.Drawing.Imaging.ImageFormat.Jpeg)

All i want to do is load the dxf file to the CADImage object, and convert it to JPG; However, when i do it in the ASP.NET there is an error message saying "invalid parameters", can someone explain a bit?

Hello,

Before saving image to the file it is necessary to call CADImage.Draw

The following code demonstrates how it can be done:

Code: Select all

FCADImage.LoadFromFile(@"D:\1.dxf"); 
Bitmap b1 = new Bitmap(500, 500);
FCADImage.Draw(Graphics.FromImage(b1), new RectangleF(0, 0, b1.Width, b1.Height));
FCADImage.SaveToFile(@"D:\1.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

For anyone interested, in ASP.NET you usually are not trying to save a file locally. Most of the time the idea is to prepare the image for downloading. The link below contains example code in C# on how to do that from a .NET ASHX handler.

Hello,

If they don't use absolute paths it is possible to go by the following way:

Code: Select all

FCADImage.SaveToFile(@"http://localhost/MyDir/1.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

Nevertheless you can get absolute path using 'Server.MapPath'.
