Add a Bitmap image in a PDF document in Android - pdf

Question

please, how can i directly pass a bitmap image to a pdf file. I have made a graph with GraphView and at the end i convert it to Bitmap, inside an OnClickListener:
write.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View arg0) {
Bitmap bitmap;
graph.setDrawingCacheEnabled(true);
bitmap = Bitmap.createBitmap(graph.getDrawingCache());
graph.setDrawingCacheEnabled(false);
String filename = "imagen";
FileOperations fop = new FileOperations();
fop.write(filename, bitmap);
if (fop.write(filename,bitmap)) {
Toast.makeText(getApplicationContext(),
filename + ".pdf created", Toast.LENGTH_SHORT)
.show();
} else {
Toast.makeText(getApplicationContext(), "I/O error",
Toast.LENGTH_SHORT).show();
}
}
});
The problem is that in the class FileOperations:
public FileOperations() {
}
public Boolean write(String fname, Bitmap bm) {
try {
String fpath = "/sdcard/" + fname + ".pdf";
File file = new File(fpath);
if (!file.exists()) {
file.createNewFile();
}
Document document = new Document();
PdfWriter.getInstance(document,
new FileOutputStream(file.getAbsoluteFile()));
document.open();
String filename = bm.toString();
com.itextpdf.text.Image image =com.itextpdf.text.Image.getInstance(filename);
document.add(image);
document.add(new Paragraph("Hello World2!"));
// step 5
document.close();
Log.d("Suceess", "Sucess");
return true;
} catch (IOException e) {
e.printStackTrace();
return false;
} catch (DocumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return false;
}
}
}
I want to know how can i pass the bitmap Image to add it in the pdf document, i do this but i think this works only when i give it a path.
String filename = bm.toString();
com.itextpdf.text.Image image =com.itextpdf.text.Image.getInstance(filename);

Answer 1

I just solve it:
document.open();
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG, 100 , stream);
Image myImg = Image.getInstance(stream.toByteArray());
myImg.setAlignment(Image.MIDDLE);
document.add(myImg);
in the FileOperations class
