@jVivek

Can you please explain a bit more about what type of issue are you facing? Are you facing some exception or output image is not as per your expectations? Please try to use the latest version of the API and provide us the requested information if you still notice any issues with it.

@jVivek

Looks like you are using Aspose.Words to generate PDF from HTML and then using Aspose.PDF to convert obtained PDF into an image.

Can you please try with 24.12 version of each API? If issue still persists, please share following:

PDF document generated by Aspose.Words (instead of saving to stream, please try to save it to file path)
Image generated by Aspose.PDF 24.12

@jVivek

Looks like the origin of exception is Aspose.Words. We have moved the thread to respective category where you will be assisted shortly.

jVivek · January 15, 2025, 4:23am

Hello @asad.ali
Where did you move this could you please tag me their and we have a license of Aspose-words and aspose-pdf then could you please suggest me where i can get quick assistance about it

@alexey.noskov could you please help above topic

alexey.noskov · January 15, 2025, 6:22am

@jVivek Unfortunately, I cannot reproduce the problem on my side. I can successfully converted your HTML document to images using the following simple code:

Document doc = new Document("C:\\Temp\\in.html");
PageSetup ps = doc.getFirstSection().getPageSetup();
// Set margins.
ps.setTopMargin(0);
ps.setBottomMargin(0);
ps.setLeftMargin(0);
ps.setRightMargin(0);
// Set page size and orientation.
ps.setPaperSize(PaperSize.A3);
ps.setOrientation(Orientation.LANDSCAPE);

ImageSaveOptions opt = new ImageSaveOptions(SaveFormat.PNG);
for (int i = 0; i < doc.getPageCount(); i++)
{
    opt.setPageSet(new PageSet(i));
    doc.save("C:\\Temp\\out_" + i + ".png", opt);
}
