Thank you received: 0

After the PDF is opened, I executed the code below:

float w = pdfReader.PDFGetDoc().GetPageWidth(0);
float h = pdfReader.PDFGetDoc().GetPageHeight(0);
float ih = 44 * getDensity();
float iw = ih / h * w;
Page page = pdfReader.PDFGetDoc().GetPage(0);
Bitmap bmp = Bitmap.createBitmap((int) iw, (int) ih, Bitmap.Config.ARGB_8888);
bmp.eraseColor(Color.WHITE);
page.RenderThumb(bmp);

However, the bmp object is still blank. Did I miss out something?
