PDF and/or Words - Splitting SVG across pages

Aspose.Total Product Family
1

Hi,


We have a very long SVG image that we would like to insert into a PDF and/or Word document. When doing this, Aspose scales the image down so that it is very small and impossible to read. Is it possible to have Aspose split the SVG image across multiple pages?

See attached SVG file.

Thanks!

Hi Joel,


Thanks for your inquiry.

Please note that Aspose.Words tries to mimic the same behavior as MS Word do. The SVG is not directly supported in Microsoft Word document, so during inserting SVG image, it will be converted to a format supported by Microsoft Word document and then inserted. Also, Microsoft Word natively supports image formats like Wmf, Emf, Jpeg, Png, Pict.

The problem occurs because the size of image is bigger than max allowed size of MS Word page. Please use the following code snippet to achieve your requirement. Hope this helps you.

Hi Joel,


Thanks for contacting support.

I have tried converting the SVG file to PDF format using Aspose.Pdf for .NET 8.3.0 and as per my observations, the contents are overlapping in resultant file. For
the sake of correction, I have logged it in our issue tracking system as PDFNEWNET-35738. We
will investigate this issue in details and will keep you updated on the status
of a correction.

We apologize for your inconvenience.

Hi Joel,


Thanks for your patience. As stated above your reported issue has been fixed in Aspose.Pdf for .NET 9.4.0. Please check following code snippet for the purpose.

SvgLoadOptions options = new SvgLoadOptions();<o:p></o:p>

options.ConversionEngine = SvgLoadOptions.ConversionEngines.NewEngine;

options.PageInfo.Margin.Top = 0;

options.PageInfo.Margin.Left = 0;

options.PageInfo.Margin.Bottom = 0;

options.PageInfo.Margin.Right = 0;

string inFile = @"35738.svg";

string outFile = @"35738.pdf";

Document pdfDocument = new Document(inFile, options);

pdfDocument.Save(outFile);


Please feel free to contact us for any further assistance.
