Convert pdf to svg by pages



Aspose provides

(1)Convert All PDF Pages to PNG Images

// For complete examples and data files, please go to
// Open document
Document pdfDocument = new Document(“input.pdf”);

// Loop through all the pages of PDF file
for (int pageCount = 1; pageCount <= pdfDocument.getPages().size(); pageCount++) {
// Create stream object to save the output image imageStream = new“Converted_Image” + pageCount + “.png”);

// Create Resolution object
Resolution resolution = new Resolution(300);
// Create PngDevice object with particular resolution
PngDevice pngDevice = new PngDevice(resolution);
// Convert a particular page and save the image to stream
pngDevice.process(pdfDocument.getPages().get_Item(pageCount), imageStream);

// Close the stream


(2) Convert PDF to SVG
Document doc = new Document(“D:\test.pdf”);
// instantiate an object of SvgSaveOptions
SvgSaveOptions saveOptions = new SvgSaveOptions();
// do not compress SVG image to Zip archive
saveOptions.CompressOutputToZipArchive = false;
// resultant file name
String outFileName = “D:\Output.svg”;
// save the output in SVG files, saveOptions);

Do you show me the sample code for convert pdf all pages to SVG ? Just like (1) which has “PngDevice.process” for each page of pdf, looking for the similar way for “svg”. Now only “convert whole
pdf file to one SVG image”.





Thank you for contacting support.

You may iterate through each page and save it to SVG format one after another. Below is a code snippet for your kind reference.

// Load PDF document
Document document = new Document(dataDir + "pdfSource_Greg.pdf");
foreach (Aspose.Pdf.Page page in document.Pages)
    Document doc = new Document();
    // Instantiate an object of SvgSaveOptions
    SvgSaveOptions saveOptions = new SvgSaveOptions();
    // Do not compress SVG image to Zip archive
    saveOptions.CompressOutputToZipArchive = false;
    // Save the output in SVG files
    doc.Save(dataDir + "PDFToSVG_"+ page.Number +"_out.svg", saveOptions);

We hope this will be helpful. Please feel free to contact us if you need any further assistance.



Thanks for the sample code and it works.
However, in some case, the result is not expected.

Please see the attached input.pdf and output_screenshot, you will see the problem.
