Public API and Backward Incompatible Changes
This section lists public API changes that were introduced in GroupDocs.Annotation for .NET 17.3.0. It includes not only new and obsoleted public methods, but also a description of any changes in the behavior behind the scenes in GroupDocs.Annotation which may affect existing code. Any behavior introduced that could be seen as a regression and modifies existing behavior is especially important and is documented here.
DjVu
DjVu files after the annotation has been added will be saved to PDF file format:
List<AnnotationInfo> annotations = new List<AnnotationInfo>();
AnnotationConfig cfg = new AnnotationConfig();
cfg.StoragePath = "StorageFolder";
AnnotationImageHandler annotator = new AnnotationImageHandler(cfg);
AnnotationInfo pointAnnotation = new AnnotationInfo()
{
PageNumber = 5,
Type = AnnotationType.Point,
Box = new Rectangle(100, 100, 0, 0),
FieldText = "Hello!",
CreatorName = "John"
};
annotations.Add(pointAnnotation);
Stream cleanImage = Assembly.GetExecutingAssembly().GetManifestResourceStream("0.djvu");
//result is PDF file
Stream result = annotator.ExportAnnotationsToDocument(cleanImage, annotations, DocumentType.Images);
using (FileStream fileStream = new FileStream("Annotated.pdf"),FileMode.Create))
{
byte[] buffer = new byte[result.Length];
result.Seek(0, SeekOrigin.Begin);
result.Read(buffer, 0, buffer.Length);
fileStream.Write(buffer, 0, buffer.Length);
}
DICOM
DICOM-files after the annotation has been added will be saved to BMP file:
List<AnnotationInfo> annotations = new List<AnnotationInfo>();
AnnotationConfig cfg = new AnnotationConfig();
cfg.StoragePath = "StorageFolder";
AnnotationImageHandler annotator = new AnnotationImageHandler(cfg);
AnnotationInfo pointAnnotation = new AnnotationInfo()
{
PageNumber = 0,
Type = AnnotationType.Point,
Box = new Rectangle(100, 100, 0, 0),
FieldText = "Hello!",
CreatorName = "John"
};
annotations.Add(pointAnnotation);
Stream cleanImage = Assembly.GetExecutingAssembly().GetManifestResourceStream("0.dcm");
//result as bmp file
Stream result = annotator.ExportAnnotationsToDocument(cleanImage, annotations, DocumentType.Images);
using (FileStream fileStream = new FileStream("Annotated.bmp"),FileMode.Create))
{
byte[] buffer = new byte[result.Length];
result.Seek(0, SeekOrigin.Begin);
result.Read(buffer, 0, buffer.Length);
fileStream.Write(buffer, 0, buffer.Length);
}
CAD-files (DWG)
CAD-files after the annotation has been added will be saved to BMP file:
List<AnnotationInfo> annotations = new List<AnnotationInfo>();
AnnotationConfig cfg = new AnnotationConfig();
cfg.StoragePath = "StorageFolder";
AnnotationImageHandler annotator = new AnnotationImageHandler(cfg);
AnnotationInfo distanceAnnotation = new AnnotationInfo()
{
CreatedOn = DateTime.Now,
Type = AnnotationType.Distance,
Box = new Rectangle(20, 20, 250, 250),
BackgroundColor = -15988609,
Text = "500px",
FontFamily = "Arial"
};
annotations.Add(distanceAnnotation);
Stream cleanImage = Assembly.GetExecutingAssembly().GetManifestResourceStream("0.dwg");
//result as bmp file
Stream result = annotator.ExportAnnotationsToDocument(cleanImage, annotations, DocumentType.Images);
using (FileStream fileStream = new FileStream("Annotated.bmp"),FileMode.Create))
{
byte[] buffer = new byte[result.Length];
result.Seek(0, SeekOrigin.Begin);
result.Read(buffer, 0, buffer.Length);
fileStream.Write(buffer, 0, buffer.Length);
}
EMF/WMF
EMF/WMF-files after the annotation has been added will be saved to PNG files:
List<AnnotationInfo> annotations = new List<AnnotationInfo>();
AnnotationConfig cfg = new AnnotationConfig();
cfg.StoragePath = "StorageFolder";
AnnotationImageHandler annotator = new AnnotationImageHandler(cfg);
AnnotationInfo distanceAnnotation = new AnnotationInfo()
{
CreatedOn = DateTime.Now,
Type = AnnotationType.Distance,
Box = new Rectangle(20, 20, 250, 250),
BackgroundColor = -15988609,
Text = "500px",
FontFamily = "Arial"
};
annotations.Add(distanceAnnotation);
Stream cleanImage = Assembly.GetExecutingAssembly().GetManifestResourceStream("0.wmf");
//result as bmp file
Stream result = annotator.ExportAnnotationsToDocument(cleanImage, annotations, DocumentType.Images);
using (FileStream fileStream = new FileStream("Annotated.png"),FileMode.Create))
{
byte[] buffer = new byte[result.Length];
result.Seek(0, SeekOrigin.Begin);
result.Read(buffer, 0, buffer.Length);
fileStream.Write(buffer, 0, buffer.Length);
}
