CADToPDF exports a blank page

[EBrown]

I am using the demo library, but I'm told that it should be fully functional. The code executes without any obvious errors, but the PDF file I get as output is simply a blank file.

My code is this:

Code: Select all

public bool SaveToPDF(string strSrc, string strDest) {
 bool success = false;

 try {
  CADImage img = new CADImage();
  img.UseDoubleBuffering = false;

  img.GraphicsOutMode = DrawGraphicsMode.Export;

  img.LoadFromFile(strSrc);
  img.GetExtents();

  CADImport.Export.CADToPDF c2p = new CADImport.Export.CADToPDF(img);

  if (System.IO.File.Exists(strDest)) File.Delete(strDest);
  c2p.SaveToFile(strDest);
  success = true;
 } catch (Exception ex) {
 }
 return success;
}

Please help? Thanks in advance!

Hello.
CAD Import .NET provides a set of classes for import different formats. Each class must be used to import corresond format. For example CADImage class provided for import DXF files, DWGImage - for import DWG. An attempt to import file of other than DXF format with your code will result in blank screen visualization. Further export to PDF will generate a blank page.
Generally we recommend to call CADImage.CreateImageByExtension method that creates object of required class for specified file extention.

Code: Select all

 try {
  CADImage img = CADImage.CreateImageByExtension(strSrc);
  img.UseDoubleBuffering = false;

Wonderful! That did the trick.

It would be useful if the documentation commented on this being the better way to load an existing file.

Thanks!
