Webrtc Go created PDFBOX-2083:
---------------------------------
Summary: Some characters overlap other characters, font changed
Key: PDFBOX-2083
URL: https://issues.apache.org/jira/browse/PDFBOX-2083
Project: PDFBox
Issue Type: Bug
Environment: windows8
Reporter: Webrtc Go
Hi, please forgive my english first.
I tried to convert a pdf file to images, using pdfbox 1.8.4 within
tika-app-1.5.jar.
The jpeg files I got were not ideal.
The content in the images were different from the pdf file.
Some characters were in different places, and some characters overlapped others.
There were many lines of console information which read:
'13:49:07,094 WARN [PDSimpleFont:107] Changing font on <l> from <Courier New
Italic> to the default font
13:49:07,094 WARN [PDSimpleFont:107] Changing font on <l> from <Courier New
Italic> to the default font
13:49:07,095 WARN [PDSimpleFont:107] Changing font on <y> from <Courier New
Italic> to the default font
13:49:07,095 WARN [PDSimpleFont:107] Changing font on <l> from <Courier New
Italic> to the default font
...'
Could you give me some instruction, tell me how to solve this problem, how to
get ideal images?
Thanks a lot.
I attached the pdf file and one of the images.
And here are my code:
PDDocument doc = PDDocument.load(input + ".pdf");
List<PDPage> pages = doc.getDocumentCatalog().getAllPages();
for (int i = 0; i < pages.size(); i++) {
PDPage page = pages.get(i);
BufferedImage image = page.convertToImage();
Iterator<ImageWriter> iter = ImageIO.getImageWritersBySuffix("JPG");
ImageWriter writer = iter.next();
File outFile = new File(input + i + ".jpg");
FileOutputStream out = new FileOutputStream(outFile);
ImageOutputStream outImage = ImageIO.createImageOutputStream(out);
writer.setOutput(outImage);
writer.write(new IIOImage(image, null, null));
writer.dispose();
out.close();
}
doc.close();
