Slow Performance About Html To Pdf in .net Core 2.1

Aspose.PDF Product Family
#1

Hi ,

I have 150 KB html file and we want to generate pdf and get pdf bytes , but its very slow to creating Document class and increasing the document size (150KB to 340 KB) after converting to PDF.

i have another scenario another html tags to converting to PDF but just only “<p>Hello World</p>” and converting to pdf.The output pdf size is 28 KB.

I think it’s so high.

So how can i manage with this ?

Thank you , best regards.

[C#]

       string html = "<p>Hello World!</p>";

        byte[] bytes = UTF8Encoding.UTF8.GetBytes(html);

        HtmlLoadOptions options = new HtmlLoadOptions();
        Document document = new Document(new MemoryStream(bytes), options);
        Aspose.Pdf.Optimization.OptimizationOptions optimizationOptions = new Aspose.Pdf.Optimization.OptimizationOptions
        {
            RemoveUnusedObjects = true,
            RemoveUnusedStreams = true,.
            AllowReusePageContent = true,
        };
        document.OptimizeResources(optimizationOptions);
        MemoryStream memoryStream = new MemoryStream();
        document.Save(memoryStream, SaveFormat.Pdf);
        document.Save(@"C:\pdfFiles\fksp5.pdf");

Thanks for your inquiry.

Please note that Aspose.PDF API loads different resources into memory (when program launches first time) which need to be used most and frequently during processing of document. Which is why you will notice significant difference of time consumption between multiple runs of a program.

We have also tested the scenario in our environment where you code took 28 seconds for the first launch and subsequent running of same code took only ~7 seconds.

As far as the size of output document concerned, we have logged an investigation ticket in our issue tracking system as PDFNET-46292. We will definitely investigate the issue and keep you posted with the status of ticket resolution. Please be patient and spare us little time.

We are sorry for the inconvenience.

Thank you @asad.ali ,

I think 7 seconds is to much to converting because it’s just write to Hello World :relaxed: .Our company recently buy the license(Site Small Business).
So this case urgent for our side.

We’re waiting.
