I think the issue is that the required font it not on the Azure Kubernetes
image that we are now running on. We are not allowed to load any fonts on
this image. Is there a way to embed the required font into the java code that
is creating the image from the PDF file? The java code is included below:
public class PDFToImage {
public static Object transformMessage(String baos) throws Exception
{
ByteArrayOutputStream[] imageBaos;
byte[] decodedString =
Base64.getDecoder().decode(baos.getBytes("UTF-8"));
// Get the input stream
try(PDDocument pddDoc = Loader.loadPDF(decodedString) ){
PDFRenderer pr = new PDFRenderer (pddDoc);
int pageCount = pddDoc.getNumberOfPages();
BufferedImage bim = new BufferedImage(25,25,
BufferedImage.TYPE_INT_ARGB);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
imageBaos = new ByteArrayOutputStream[pageCount];
for (int page = 0; page<pageCount;page++) {
BufferedImage bimage = pr.renderImageWithDPI(page, 150,
ImageType.RGB);
bim = joinBufferedImage(bim,bimage);
}
ImageIO.write(bim, "png", stream);
pddDoc.close();
byte[] bytes = stream.toByteArray();
return bytes;
} catch (IOException e) {
e.printStackTrace();
throw new Exception(e);
}
}
private static BufferedImage joinBufferedImage(BufferedImage img1,
BufferedImage img2) {
// TODO Auto-generated method stub
int offset = 5;
int wid = Math.max(img1.getWidth(),img2.getWidth() + offset);
int height = img1.getHeight() + img2.getHeight() + offset;
BufferedImage newImage = new
BufferedImage(wid,height,BufferedImage.TYPE_INT_RGB);
Graphics2D g2 = newImage.createGraphics();
Color oldColor = g2.getColor();
g2.setPaint(Color.WHITE);
g2.fillRect(0, 0, wid, height);
g2.setColor(oldColor);
g2.drawImage(img1, null, 0, 0);
g2.drawImage(img2, null, 0, img1.getHeight() + offset);
g2.dispose();
return newImage;
}
}

Hi,
I tested with 3.0.1 and got one log message:
Unexpected XRefTable Entry: 0 24
that's because that line is " 0 24" instead of "0 24". However that
doesn't seem to have a negative effect. Here's how the image looks:

Hi,
We'd need the PDF file, please upload to a sharehoster. Your attachments (all
of them) didn't get through.
Also try to use the latest snapshot
https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/pdfbox-app/3.0.2-SNAPSHOT/
and look at the log messages.

*Subject:* PDFBox 3.0.1 Font changes when rendering PDF to Image
Hi,
I am using PDFBox to render a PDF to a .png image. In the past, I
used version 2.0.23 which worked without issue. When the image is
rendered in verion 3.0.1, the text part of the PDF document does not
properly convert the Font (Times Roman). How can I fix this issue?
I have attached the images to show the comparison of what is being
rendered in version 3.0.1 versus 2.0.23.
Thanks for any help you can provide.
