Hi:

Attached is a zip file containing a 1 page PDF scanned
PDF doc and the image extracted using pdfBox.

As you can see, the PDF file shows the document fine,
but the image (which it saved with suffix png.png) is
completely garbled.

I have tried the following ways, all with the same
result:

(a) PDPage.convertToImage() --> BufferedImage -->
ImageIO.write(image,"png",...)

Code:

PDDocument document = PDDocument.load("test3.pdf");
List pages = document.getDocumentCatalog().getAllPages
();
PDPage page = (PDPage)pages.get(0);
BufferedImage image = page.convertToImage();
ImageIO.write(image, "png", new File("test31.png"));

(b) PDPage --> PDResources --> getImages() --> obtain
the PDXObjectImage() from iterator --> getRGBImage() -
-> BufferedImage --> ImageIO.write().

PDDocument document = PDDocument.load("test3.pdf");
List pages = document.getDocumentCatalog().getAllPages
();
PDPage page = (PDPage)pages.get(0);
PDResources resources = page.getResources();
Map images = resources.getImages();
if( images != null )
{
Iterator imageIter = images.keySet().iterator();
while( imageIter.hasNext() )

{ String key = (String)imageIter.next(); PDXObjectImage image = (PDXObjectImage) images.get( key ); image.write2file("test3."+image.getSuffix()); BufferedImage bufImg = image.getRGBImage(); ImageIO.write(bufImg, "png", new File ("test31.png")); }

}

Please let me know!
