StampAnnotation read image data

Aspose.PDF Product Family
1

Is there any way to read the image data for a saved StampAnnotation? The getImage function returns null for saved documents.

Code;

  File oPath = new File(Environment.getExternalStorageDirectory(), "Documents");
  File oPdfLic = new File(oPath, "aspose_pdf.lic");
  File oPdfIn = new File(oPath, "test.pdf");
  File oPdfOut = new File(oPath, "test2.pdf");
  File oImage = new File(oPath, "test.jpg");


  FileInputStream oStream = new FileInputStream(oPdfLic.getAbsolutePath());
  License oLicense = new License();
  oLicense.setLicense(oStream);
  oStream.close();

  // create document
  {
    com.aspose.pdf.Document oDoc = new com.aspose.pdf.Document(oPdfIn.getAbsolutePath());
    Page oPage = oDoc.getPages().get_Item(1);

    FileInputStream oInFile = new FileInputStream(oImage.getAbsolutePath());

    Rectangle oImgRect = new Rectangle(5f, 5f, 150f, 150f);
    StampAnnotation oStamp = new StampAnnotation(oPage, oImgRect);

    oStamp.setImage(oInFile);

    oPage.getAnnotations().add(oStamp);
    oInFile.close();

    oPdfOut.delete();
    oDoc.save(oPdfOut.getAbsolutePath());
    oDoc.close();
  }

  // use saved document
  {
    com.aspose.pdf.Document oDoc = new com.aspose.pdf.Document(oPdfOut.getAbsolutePath());
    Page oPage = oDoc.getPages().get_Item(1);

    StampAnnotation oStamp = (StampAnnotation) oPage.getAnnotations().get_Item(1);

    // stream is null //
    InputStream oStreamIsNull = oStamp.getImage();
    log("onCreate", "is null: " + (oStreamIsNull == null));
  }

Hello, I have the same problem that the Image property in Stamp Annotation returns null value when I try to get the image stream. Here is my code:
foreach(Annotation annotation in pdfDocument.Pages[i+1].Annotations){
StampAnnotation stamp = (StampAnnotation) annotation;
combinedText += String.Format(“image {0},”,stamp.Image == null ? “true” : “false”);
}
The stamp.Image will return null which results in output “true” in this case, this is C#, not Java. Please help me! Thank you.

TYPES.pdf (235.7 KB)
for(int i = 0;i < 19;i++){
foreach(Annotation annotation in pdfDocument.Pages[i+1].Annotations){
var name = annotation.AnnotationType.ToString();
if(name == “Polygon”){
PolygonAnnotation polygon = (PolygonAnnotation) annotation;
combinedText += String.Format("{0},",polygon.Subject);
}
else if(name == “Stamp”){
StampAnnotation stamp = (StampAnnotation) annotation;
combinedText += String.Format(“image {0},”,stamp.Image == null ? “true” : “false”);
}
else{
combinedText += String.Format("{0},",name);
}
}
}
Here is the pdf document and the sample code, it has 19 pages, and the last page has all the stamps. Thank you for your help.

Hello, I am just checking on the progress of ticket PDFNET-51839? Any progress so far?
By the way, in Annotation class, there is a function called ToImage(), but it is a protected class, is there anyway I can get the image stream for each annotation in a PDF file?
Thank you
