Steps to Remove Annotations from DCM in Net

GroupDocs.Annotation makes it easier for Net developers to remove annotation details from DCM files within any Net-based application by implementing a few easy steps.

  • Create Reply objects with comment and date.
  • Instantiate SaveOptions object and set AnnotationTypes = AnnotationType.None.
  • Call save method with resultant document path or stream and SaveOptions object.

// 1- How to remove annotation from document using annotation index

using (Annotator annotator = new Annotator("result.bmp"))
{
    annotator.Remove(0);
    annotator.Save("removed.bmp");
}

// 2- How to remove annotation from document using annotation object

using (Annotator annotator = new Annotator("result.bmp"))
{
    var tmp = annotator.Get();
    annotator.Remove(tmp[0]);
    annotator.Save("removed.bmp");
}

// 3- How to remove some annotations from document using list of ID’s

using (Annotator annotator = new Annotator("result.bmp"))
{
    var idList = new List{1, 2, 3};
    annotator.Remove(idList);
    annotator.Save("removed.bmp");
}

// 4- How to remove some annotations from document using list of annotations

using (Annotator annotator = new Annotator("result.bmp"))
{
    var tmp = annotator.Get();
    annotator.Remove(tmp);
    annotator.Save("removed.bmp");
}

Steps to Edit Annotations from DCM in Net

GroupDocs.Annotation makes it easier for Net developers to update various annotation properties from DCM files within any Net-based application by implementing a few easy steps.

  • Instantiate Annotator object with input document path or stream with instantiated LoadOptions with ImportAnnotations = true.
  • Create some AnnotationBase implementation and set Id of existed annotation (if annotation with that Id not found, nothing will be changed) or path list of annotations (all existed annotations will be removed).
  • Call update method of Annotator object with passed annotations.
  • Call save method with resultant document path or stream and SaveOptions object.

// open annotated document
using (Annotator annotator = new Annotator("result.bmp"))
{
    //assuming we are going to change some properties of existing annotation
        AreaAnnotation updated = new AreaAnnotation
            {
                    // It's important to set existed annotation Id
                    Id = 1,
                    BackgroundColor = 255,
                    Box = new Rectangle(0, 0, 50, 200),
                    CreatedOn = DateTime.Now,
                    Message = "This is updated annotation",
                    Replies = new List
                    {
                        new Reply
                        {
                            Comment = "Updated first comment",
                            RepliedOn = DateTime.Now
                        },
                        new Reply
                        {
                            Comment = "Updated second comment",
                            RepliedOn = DateTime.Now
                        }
                    }
                };
        // update annotation
        annotator.Update(updated);
        annotator.Save("result.bmp");
}

Steps to Extract Annotations from DCM in Net

GroupDocs.Annotation makes it easy for Net developers to annotate documents and extract annotation information from DCM files within any Net-based application by implementing a few easy steps.

  • Create Reply objects with comment and date.
  • Instantiate LoadOptions object and call SetImportAnnotations with true argument.
  • Define variable with type List.
  • Call get method and return result to variable above.

// for using this example input file ("annotated.bmp") must be with annotations
using (Annotator annotator = new Annotator("annotated.bmp"))
{
    List annotations = annotator.Get();
    XmlSerializer formatter = new XmlSerializer(typeof(List));
    using (FileStream fs = new FileStream("annotations.xml", FileMode.Create))
    {
        fs.SetLength(0);
        formatter.Serialize(fs, annotations);
    }
}

About DCM File Format

Files with .DCM extension represent digital image which stores medical information of patients such as MRIs, CT scans and ultrasound images. It was developed by the National Electrical Manufacturers Association (NEMA) and was meant to standardize the imaging file format for distribution and viewing of medical images. It is similar to DICOM file format and can include patient’s information for reference.
