Using PDFBox change PDF file to Bitmap, but meet some highlight part, so i got a poor conversion...

this is the wrong file page preview:

and my code :

PDDocument document = PDDocument.load(assetManager.open("XXX.pdf"));
PDFRenderer renderer = new PDFRenderer(document);
pageImage = renderer.renderImage(0, 1, ImageType.ARGB);

// Save the render result to an image
String path = root.getAbsolutePath() + "/render.png";
File renderFile = new File(path);
FileOutputStream fileOut = new FileOutputStream(renderFile);
pageImage.compress(Bitmap.CompressFormat.PNG, 100, fileOut);
fileOut.close();

And then I got this result Image：
