issues with PDF to HTML conversion with Arabic text

[mgalal123]

Hi,
I converted a PDF with English and Arabic text using saveToStream(outStream, FileFormat.HTML) which produced miss formed Arabic text.

Attached are the PDF and generated HTML.

it's been more than one month since we raised this. I wonder if you have put it in the right queue given we have purchased extra support license which should give our issues more priority.

Hi,
Don't you think this is too much time to fix an issue like this ? Has anyone checked it at all or it has been just ignored or missed in your records ?

Hello,

We did not miss SPIREPDF-5587 issue and have been working on it. But it does have a lot of difficulty and complexity.

For hyphenated types like Arabic characters, displaying PDF content in Adobe is rendered using unicode and glyphs corresponding to each other. We found that browsers (such as Google and Internet Explorer) have their own internal rules for handling hyphenated languages that differ from Adobe's. We also found that different browsers, such as Google and Internet Explorer, display different results.

At present, our developers are taking a long time to investigate the processing rules of the browsers and have not fully investigated it yet. Please give us more time. Thank you for your understanding and support.

Hi,
Thanks for your reply.
At least for now we would expect a workaround to move forward. So please ask your development team to suggest another way of implementation to ensure we are not impacted by this issue.

Hi,

Thanks for your understanding.
Are you willing to accept the solution of first converting PDF to image and draw the image to a new PdfDocument, and then converting it to HTML files?
sampe code:

Code: Select all

        PdfDocument doc = new PdfDocument();
        doc.loadFromFile(folder+"source.pdf");
        PdfDocument pdfDocument = new PdfDocument();
        PdfPageBase pdfPageBase;
        for (int i = 0; i < doc.getPages().getCount(); i++) {
            pdfPageBase = pdfDocument.getPages().add(doc.getPages().get(i).getSize(),new PdfMargins(0));
            BufferedImage bufferedImage = doc.saveAsImage(i);
            pdfPageBase.getCanvas().drawImage(PdfImage.fromImage(bufferedImage),0,0);
            bufferedImage.getGraphics().dispose();
        }
        //Set the conversion option to embed image in html
        pdfDocument.getConvertOptions().setPdfToHtmlOptions(true,true);
        //Convert to html file
        pdfDocument.saveToFile(folder+"1.html", FileFormat.HTML);
        pdfDocument.close();
        doc.close();
