Usage examples:

CADNET-19 Convert/Export images to DXF file formates

  • Set new font
  • Hide entities
  • Update text
 foreach(var file in new DirectoryInfo(filesDir).EnumerateFiles("*.dxf")) {

 // ****************************

 //  Set new font per document

 // ****************************

 using(var cadImage = (CadImage) Image.Load(file.FullName)) {

  // Iterate over the items of CadStyleTableObject

  foreach(CadStyleTableObject style in cadImage.Styles) {

   // Set font name

   style.PrimaryFontName = "Broadway";

  }

  cadImage.Save(file.FullName + "_font.dxf");

 }

 // ****************************

 //  Hide all "straight" lines

 // ****************************

 using(var cadImage = (CadImage) Image.Load(file.FullName)) {

  foreach(var entity in cadImage.Entities) {

   // Make lines invisible

   if (entity.TypeName == CadEntityTypeName.LINE) {

    entity.Visible = 0;

   }

  }

  cadImage.Save(file.FullName + "_lines.dxf");

 }

 // ****************************

 //  Manipulations with text

 // ****************************

 using(var cadImage = (CadImage) Image.Load(file.FullName)) {

  foreach(var entity in cadImage.Entities) {

   if (entity.TypeName == CadEntityTypeName.TEXT) {

    ((CadText) entity).DefaultValue = "New text here!!! :)";

    break;

   }

  }

  cadImage.Save(file.FullName + "_text.dxf");

 }

}

CADNET-712 Distinguish between DWT and DWG formats from provided drawing stream

 var formatTypeDwt = Image.GetFileFormat(GetFileFromDesktop("sample.dwt"));

Assert.IsTrue(formatTypeDwt.ToString().ToLower().Contains("dwt"));

var formatTypeDwg = Image.GetFileFormat(GetFileFromDesktop("sample.dwg"));

Assert.IsTrue(formatTypeDwg.ToString().ToLower().Contains("dwg"));
