How to convert pdf to png in Android?

Question

A little problem i'm having right now with my app. I've found solutions in Java, using Ghost4J... But it uses java.awt.Image, that I can't import in Android. I java, I have something like that :

PDFDocument document = new PDFDocument();
                document.load(file);

                SimpleRenderer renderer = new SimpleRenderer();
                renderer.setResolution();

                List<Image> images = renderer.render(document);
                for (int i = 0; i < images.size(); i++) {
                    ImageIO.write((RenderedImage) images.get(i), "png", new File((i + 1) + ".png"));
                }

So, my problem is that I have a picture in pdf format, and I need to convert it in png, cause I use a printer that can't handle pdf...

Hope you guys, will find a way... Thanks a lot, and sorry for my english!

I don't think that the screenshot is what he wants. Imagine that the user zoom on particular zone in the PDF. if he takes a screenshot, his image will cover only the active zone and not all the page — Mohamed Amjad LASRI, Dec 29 '15 at 16:26

PdfRenderer is what you are looking for. More precisely: the method render in the PdfRender.Page class.

void    render(Bitmap destination, Rect destClip, Matrix transform, int renderMode)

it runders the PDF page to a bitmap. And then from bitmap to PNG use the method bitmap.compress

Thanks for your answer, didn't know that... But it appears that it needs api 21, my current min in 15... Is there a way for earlier versions? Thx – Dec 29 '15 at 17:08
