Shigeru Okada updated PDFBOX-5140:
----------------------------------
Description:
I tried to change PDF file including Chinese font to JPG file.
Source code is as below.
private List<String> convertPdf2Jpg(File pdfFile) {
List<String> jpgList = new ArrayList<String>();
try {
PDDocument document = PDDocument.load(pdfFile);
PDFRenderer pdfRenderer = new PDFRenderer(document);
for (int i = 0; i < document.getNumberOfPages(); i++) {
BufferedImage image = null;
try{
image =
pdfRenderer.renderImageWithDPI(i, 300 ,ImageType.RGB);
String jpgName =
pdfFile.getPath().split(".pdf")[0] + "_" + String.format("%03d", i+1) + ".jpg";
ImageIOUtil.writeImage(image, jpgName,
300);
jpgList.add(jpgName);
}
catch(Exception e) {
document.close();
LOG.error(pdfFile + "(" + i + " page) "
+ " can't convert pdf to jpg file (convertPdf2Jpg())." + e.toString());
throwPdfBoxException("convertPdf2Jpg():" + pdfFile + "(" + i + " page) " + "
can't convert pdf to jpg file." + e.toString());
}
}
document.close();
}
catch(Exception e){
LOG.error(pdfFile + "Can't load PDF file
(convertPdf2Jpg()).");
}
return jpgList;
}
I attached example of PDF and JPG. Chinese characters are broken.
It seems that it depends on font.
If you need more information, please let me know.
Thanks
