Hi,
I have a pdf created with Adobe Acrobat 9, I am trying to access the
alternate text for images of this document, but always appears as null.
This is the code I'm using:
PdfReader reader = new PdfReader("c:\\tmp\\textoAlternativo.pdf");
for (int i = 0; i < reader.getXrefSize(); i++) {
PdfObject pdfobj = reader.getPdfObject(i);
if (pdfobj != null) {
if (pdfobj.isStream()) {
PdfStream stream = (PdfStream) pdfobj;
PdfObject pdfsubtype = stream.get(PdfName.SUBTYPE);
if (pdfsubtype != null) {
if (pdfsubtype.toString().equals(PdfName.IMAGE.toString()))
{
byte[] img = PdfReader.getStreamBytesRaw((PRStream)
stream);
Image img1 = Image.getInstance(img);
System.out.println("alt1 "+img1.getAlt());
System.out.println("alt2 "+stream.get(PdfName.ALT));
}
}
}
}
}
Thanks,
Juan Antonio Mayol
