Check whether external referenced images exist and replace references

How to edit of hyperlinks on objects

Issue: How to check whether external referenced images exist and replace references (CADNET-8088).

Tips: To do this, get an entity of type CadObjectTypeName.IMAGEDEF from the drawing entities and use CadRasterImageDef to check.

Example:

foreach (CadBaseObject baseObject in cadImage.Objects)
{
  if (baseObject.TypeName == CadObjectTypeName.IMAGEDEF)
  {
    // the relation between CadRasterImageDef (in cadImage.Objects) and CadRasterImage (in cadImage.Entities) is by
    // cadRasterImageDef.ObjectHandle == cadRasterImage.ImageDefReference

    CadRasterImageDef rasterImageDef = (CadRasterImageDef)baseObject;

    // path may be relative or absolute
    if (!File.Exists(rasterImageDef.FileName))
    {
     // rasterImageDef.FileName = @"D:\Users\Oleksii\Desktop\c2.jpg"; 
      rasterImageDef.FileName = "13521951017666.jpg";
     cadImage.UpdateSize();
    }
  }
}
