I'm trying to find the position of an xobject in an existing pdf
file. I'm wondering if there is a way to use stream.get(PdfName. . .
to return the location of the object. The code I'm using is as follows.
for (int i = 1; i < reader.getXrefSize(); i++)
{
PdfObject pdfobj = reader.getPdfObject(i);
if (!pdfobj.isStream()) {
continue;
}
PdfStream stream = (PdfStream) pdfobj;
PdfObject pdfsubtype = stream.get(PdfName.SUBTYPE);
if (pdfsubtype == null) {
continue;
}
if (!pdfsubtype.toString().equals(PdfName.IMAGE.toString())) {
continue;
}
byte[] img = PdfReader.getStreamBytesRaw((PRStream) stream);
System.out.println("height:" + stream.get(PdfName.HEIGHT));
System.out.println("width:" + stream.get(PdfName.WIDTH));
System.out.println("Position: " + stream.get(PdfName.IMAGE));
System.out.println("bitspercomponent:" +
stream.get(PdfName.BITSPERCOMPONENT));
}
}
}
