PDF and/or Words - Splitting SVG across pages


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.


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.

public static void ConvertImageToPdf(string inputFileName, string outputFileName)<o:p></o:p>


// Create Aspose.Words.Document and DocumentBuilder.<o:p></o:p>

// The builder makes it simple to add content to the document.<o:p></o:p>

Document doc = new Document();<o:p></o:p>

DocumentBuilder builder = new DocumentBuilder(doc);<o:p></o:p>

// Read the image from file, ensure it is disposed.<o:p></o:p>

using (Image image = Image.FromFile(inputFileName))<o:p></o:p>


// Get the number of frames in the image.<o:p></o:p>

int framesCount = image.GetFrameCount(FrameDimension.Page);<o:p></o:p>

// Loop through all frames.<o:p></o:p>

for (int frameIdx = 0; frameIdx < framesCount; frameIdx++)<o:p></o:p>


// Insert a section break before each new page, in case of a multi-frame TIFF.<o:p></o:p>

if (frameIdx != 0)<o:p></o:p>


// Select active frame.<o:p></o:p>

image.SelectActiveFrame(FrameDimension.Page, frameIdx);<o:p></o:p>

// Max page size<o:p></o:p>

const double maxPageHeight = 1584;<o:p></o:p>

const double maxPageWidth = 1584;<o:p></o:p>

double currentImageHeight = ConvertUtil.PixelToPoint(image.Height, image.VerticalResolution);<o:p></o:p>

double currentImageWidth = ConvertUtil.PixelToPoint(image.Width, image.HorizontalResolution);<o:p></o:p>

if (currentImageWidth >= maxPageWidth || currentImageHeight >= maxPageHeight)<o:p></o:p>


// Get max image size.<o:p></o:p>

CalculateImageSize(image, maxPageHeight, maxPageWidth, outcurrentImageHeight, out currentImageWidth);<o:p></o:p>


// We want the size of the page to be the same as the size of the image.<o:p></o:p>

// Convert pixels to points to size the page to the actual image size.<o:p></o:p>

PageSetup ps = builder.PageSetup;<o:p></o:p>

ps.PageWidth = currentImageWidth;<o:p></o:p>

ps.PageHeight = currentImageHeight;<o:p></o:p>

// Insert the image into the document and position it at the top left corner of the page.<o:p></o:p>












// Save the document to PDF.<o:p></o:p>



/// Calculates size of Image<o:p></o:p>

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.

The issues you have found earlier (filed as PDFNEWNET-35738) have been fixed in Aspose.Pdf for .NET 9.4.0.

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);


Please feel free to contact us for any further assistance.

Best Regards,
