Hi , I am able to extract images in JPEG(.jpg, .jpeg, .jpe) format only not
other.
public void extractImages(){
try{
PdfReader chartReader = new PdfReader("myPdf.pdf");
for (int i = 0; i < chartReader.getXrefSize(); i++) {
PdfObject pdfobj = chartReader.getPdfObject(i);
if (pdfobj != null && pdfobj.isStream()) {
PdfStream stream = (PdfStream) pdfobj;
PdfObject pdfsubtype = stream.get(PdfName.SUBTYPE);
//System.out.println("Stream subType: " + pdfsubtype);
if (pdfsubtype != null && pdfsubtype.equals(PdfName.IMAGE))
{
byte[] image =
PdfReader.getStreamBytesRaw((PRStream) stream);
System.out.println("Image bytes
length:"+image.length);
// byte[] image =
PdfReader.getStreamBytes((PRStream) stream);
FileOutputStream fw = new FileOutputStream(i +
".jpg");
fw.write(image);
fw.flush();
fw.close();
}
}
}
}catch(Exception e){
e.printStackTrace();
}
}
