Converting PDF to image (with proper formatting)

android, format, image, pdf, pdfbox

Solution

it turns out that jpedal(lgpl) does the converting perfectly(just like a snapshot).

here is what I have used :

PdfDecoder decode_pdf = new PdfDecoder(true);


FontMappings.setFontReplacements();

    decode_pdf.openPdfFile("Hello World.pdf"); 


 decode_pdf.setExtractionMode(0,800,3);

 try {

     for(int i=0;i<40;i++)
     {  
         BufferedImage img=decode_pdf.getPageAsImage(2+i);

    ImageIO.write(img, "png",new File(String.valueOf(i)+"out.png"));
     }
} catch (IOException ex) {
    Logger.getLogger(NewJFrame.class.getName()).log(Level.SEVERE, null, ex);
}

    decode_pdf.closePdfFile();

} catch (PdfException e) {
    e.printStackTrace();
}

it works fine.

Problem

i have a pdf file(attached). My objective is to convert a pdf to an image using pdfbox AS IT IS,(same as using snipping tool in windows). The pdf has all kinds of shapes and text . i am using the following code: ``` PDDocument doc = PDDocument.load("Hello World.pdf"); PDPage firstPage = (PDPage) doc.getDocumentCatalog().getAllPages().get(67); BufferedImage bufferedImage = firstPage.convertToImage(imageType,screenResolution); ImageIO.write(bufferedImage, "png",new File("out.png")); ``` when i use the code, the image file gives totally wrong outputs(out.png attached) how do i make pdfbox take something like a direct snapshot image? also, i noticed that the image quality of the png is not so good, is there any way to increase the resolution of the generated image? EDIT: here is the pdf(see page number 68) https://drive.google.com/file/d/0B0ZiP71EQHz2NVZUcElvbFNreEU/edit?usp=sharing EDIT 2: it seems that all the text isvanishing. i also tried using the PDFImageWriter class ``` test.writeImage(doc, "png", null, 68, 69, "final.png",TYPE_USHORT_GRAY,200 ); ``` same result
