Project: PDFBox
Issue Type: Bug
Affects Versions: 1.8.2
Environment: Windows 8
JDK 1.7
Reporter: Paulo R C Mello Junior
I'm in the fight to perfectly convert a PDF to an image.
But the stacktrace below breaks my application!

getRGBImage
SEVERE: Something went wrong ... the pixelmap doesn't contain any data.

I really need to fix this problem in order to succeed in converting
You know why this error occurs?
You know how I can fix this error?
is some dependence of my environment that i forgot? or a failure of PDFBox
framewor ?
Follow my code below:
---
public static List<BufferedImage> getPdfPagesAsImages(String pdfPath,
int i)
throws FileNotFoundException, IOException {
List<BufferedImage> bImages = new ArrayList<BufferedImage>();
File f = new File(pdfPath);
if (f.exists()) {
int resolution = 185;
PDDocument pdfDocument = null;
pdfDocument = PDDocument.loadNonSeq(f, null);
if (pdfDocument != null) {
@SuppressWarnings("unchecked")
List<PDPage> pages = (List<PDPage>) pdfDocument
.getDocumentCatalog().getAllPages();
int j = 1;
for (PDPage p : pages) {
System.out.println(j);
BufferedImage convertedImage = p.convertToImage(
BufferedImage.TYPE_INT_BGR ,
resolution);
saveImageToRepository(i, j, convertedImage);
j++;
if (isNegativeImage(convertedImage)) {
bImages.add(invertNegativeImage(convertedImage));
} else {
bImages.add(convertedImage);
}
}
System.out.println(pdfPath +" sucess");
}
pdfDocument.close();
}else{
System.out.println(pdfPath +" nao existe");
}
return bImages;
}
private static void saveImageToRepository(int i, int j,
BufferedImage convertedImage) throws IOException {
File outputfile = new File("C:/Desenvolvimento/bkp/convertido/"
+ i + j+ ".png");
ImageIO.write(convertedImage, "png", outputfile);
}
---
I create a list of images
these images are saved to be loaded in the browser later on a JSF component.
