Hello, we use code sample from Developer Guide to replace text token in PDF (which is generated from MS Word). We update PDF and save it. It usually open correctly. But if we stream PDF from web server to browser IE 11 Acrobat Reader window is opened and randomly it shows general error dialog:
Adobe Reader
An error exists on this page. Acrobat may not display the page correctly. Please contact the person who created the PDF document to correct the problem.
Problem is that this happens randomly. This did not happen before we started to update our PDF with Aspose PDF. We use latest version 11.5.0. We set font ExpertSans-Regular which is embedded and isSubset returns true.
Is there any way we could diagnose problem? I attach PDF sample.
Test_publication_3.pdf is generated from MS Word
Barclays_Test_Credit_Publication_123.pdf is created when we replace text using Aspose PDF. It sometimes causes problem as described above.
Note: I also filed separate report about growing file size during this operation which was accepted as bug here. Is it possible it could be somehow connected? PDF file size grows after simple replacement
Here is our sample code based on Developer Guide:
PdfReplacementResult result = new PdfReplacementResult();
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
try {
Document pdfDocument = new com.aspose.pdf.Document(documentStream);
for (String placeholderToReplace : textReplacementMap.keySet()) {
String textReplacement = textReplacementMap.get(placeholderToReplace);
TextFragmentAbsorber textFragmentAbsorber = new com.aspose.pdf.TextFragmentAbsorber(placeholderToReplace);
TextSearchOptions textSearchOptions = new com.aspose.pdf.TextSearchOptions(true);
textFragmentAbsorber.setTextSearchOptions(textSearchOptions);
pdfDocument.getPages().accept(textFragmentAbsorber);
com.aspose.pdf.TextFragmentCollection textFragmentCollection = textFragmentAbsorber.getTextFragments();
for (com.aspose.pdf.TextFragment textFragment : (Iterable<com.aspose.pdf.TextFragment>) textFragmentCollection) {
String foundText = textFragment.getText();
// Replace only when replacement text is different from original text
if (!foundText.equals(textReplacement)) {
textFragment.setText(textReplacement);
// Set other font for JP
Font font = FontRepository.findFont(“ExpertSans-Regular”);
textFragment.getTextState().setFont(font);
}
}
}
pdfDocument.optimize();
pdfDocument.save(outputStream);
