Dear Aspose Team,

As far as I see there is an option to save PDF files in single HTML.
But I need to convert PDF files in single HTML (all resources embedded) with stream.
Is there any examples how to do this?

Thanks

Hello Tilal,
Thank you for your response. I tried to use this example, but without success.

I got the following exception:

Inconsistent saving options detected : 'CustomStrategyOfCssUrlCreation','CustomCssSavingStrategy','CustomResourceSavingStrategy' may not be null when requested saving to stream!

And here is my code:
HtmlSaveOptions htmlSaveOps = new HtmlSaveOptions();
htmlSaveOps.RasterImagesSavingMode = HtmlSaveOptions.RasterImagesSavingModes.AsEmbeddedPartsOfPngPageBackground;
htmlSaveOps.FontSavingMode = HtmlSaveOptions.FontSavingModes.AlwaysSaveAsWOFF;
htmlSaveOps.PartsEmbeddingMode = HtmlSaveOptions.PartsEmbeddingModes.EmbedAllIntoHtml;
htmlSaveOps.LettersPositioningMethod = LettersPositioningMethods.UseEmUnitsAndCompensationOfRoundingErrorsInCss;
htmlSaveOps.setSplitIntoPages(false);
htmlSaveOps.CustomHtmlSavingStrategy = new HtmlSaveOptions.HtmlPageMarkupSavingStrategy() {
@Override
public void invoke(com.aspose.pdf.HtmlSaveOptions.HtmlPageMarkupSavingInfo htmlSavingInfo) {
// TODO Auto-generated method stub
byte[] resultHtmlAsBytes = new byte[(int) htmlSavingInfo.ContentStream.getLength()];
htmlSavingInfo.ContentStream.read(resultHtmlAsBytes, 0, resultHtmlAsBytes.length);
// here You can use any writable stream, file stream is taken
// just as example
ByteArrayOutputStream fos;
try {
fos = new ByteArrayOutputStream();
fos.write(resultHtmlAsBytes);
fos.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
};

ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
pdf.save(outputStream, htmlSaveOps);

==================================================================

Please help me solve this problem, thanks.

Hi Lai,


Thanks for your feedback. Please pay attention when saving PDF to HTML with embedded resources in a single stream you need to pass a non-existing HTML file name in save method instead stream, original saving to stream will be done in CustomHtmlSavingStrategy as stated at the end of code snippet in documentation link.

//all real saving will be done in
CustomHtmlSavingStrategy<o:p></o:p>

//ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

//pdf.save(outputStream, htmlSaveOps);

String outHtmlFile = "SomeUnexistingFile.html";

doc.save(outHtmlFile, newOptions);
