Vector graphic wmf to pdf

I am trying to turn multiple vector graphic wmf files into a single, multi page vector graphic pdf. Does anyone know how this can be done? We have Aspose.PDF but this does not seem to handle SVG files.

Hi Tony,


Adding more to Rashid’s comments, you may also consider visiting the following link for information on Use Image from Local Disk

Thanks Rashid,


I have tried the SVG converter code and I am finding that the conversion will not finish and I have to stop my program. I am using an svg file generated by a utility called emf2vec and I have used the sample code from your website for the encoding.

Also ideally what I would like is to do a straight conversion from a vector graphic wmf file to pdf but maintaining the vector graphic mode. I have used Aspose.PDF to convert from wmf to PDF but it appears to rasterise and I lose quality.

Hi Tony,

Thank you for sharing the details.

Can you please share some details regarding sample source code and template documents you are using or create a sample application to show the issue. This will help us to figure out the exact issue and reply back to you soon.

We apologize for your inconvenience.

Thanks & Regards,

Hi Rashid,


I really have just taken the code from your web site with modifications to set input and output as follows:

// instantiate LoadOption object using SVG load option
Aspose.Pdf.LoadOptions loadopt = new Aspose.Pdf.SvgLoadOptions();
// create Document object
Aspose.Pdf.Document doc = new Aspose.Pdf.Document(“c:\imagemajick\emf2vec0.svg”, loadopt);
// save the resultant PDF document
doc.Save(OutputFilePath);

When I debug it all hangs after the Aspose.Pdf.Document doc = new Aspose.Pdf.Document(“c:\imagemajick\emf2vec0.svg”, loadopt); call.

The only real unknown is the svg file that we generated from a utility we found online.I have uploaded the file. Please note that it is an svg file but the uploader will not allow svg extensions so I had to change it.

Tony

Hi Tony,

Thanks for sharing the sample source code and template document with us.

I tested the scenario using your sample source code and source SVG file and able to notice that there might be an issue with your source file. I have also tested the scenario with another sample file and it's working fine. Source and resultant documents are attached for your reference.

Please feel free to contact support in case you need any further assistance.

Thanks & Regards,

Much appreciated Rashid. Your file indeed converts fine. All I really need now is something that can convert immediately from vector graphic wmf to vector graphic pdf. Although Aspose.PDF can convert SVG files to PDF it does not look as though it can go straight from vector graphic wmf to PDF without rasterising which loses quality.

Hello Tony,


Thanks for sharing the details.

As per my understanding, you have first converted the WMF file into SVG format and then you have tried using Aspose.Pdf for .NET to convert the SVG file into PDF format. The reason you are getting error while converting SVG file into PDF format is because you have used some online utility to convert EMF file to SVG format and as a result, the SVG file got corrupted.

Can you please share the source WMF file so that we can test the conversion at our end. We are sorry for your inconvenience.

Hi Rashid,


Can you confirm if Aspose.PDF can convert from WMF to PDF but maintaining the vector graphic format for quality reasons. As stated before it looks as though the WMF file is maybe being converted to PNG and then to PDF since quality is obviously reduced. If Aspose.PDF does not do this, is there any chance it may happen in the future?

Regards

Tony

Hi Tony,

Thanks for your inquiry. Kindly use the below mentioned code for converting WMF to PDF.

[C#]

//Instantiate Pdf instance by calling its empty constructor<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Aspose.Pdf.Generator.Pdf pdf1 = new Aspose.Pdf.Generator.Pdf();

//Add a section into the pdf document

Aspose.Pdf.Generator.Section sec = pdf1.Sections.Add();

//Create a FileStream object to read the imag file

FileStream fs = File.OpenRead(@"d:\pdffiles\grid.wmf");

//Read the image into Byte array

byte[] data = new byte[fs.Length];

fs.Read(data, 0, data.Length);

//Create a MemoryStream object from image Byte array

MemoryStream ms = new MemoryStream(data);

//Create an image object in the section

Aspose.Pdf.Generator.Image imageht = new Aspose.Pdf.Generator.Image(sec);

//Set the type of image using ImageFileType enumeration

imageht.ImageInfo.ImageFileType = Aspose.Pdf.Generator.ImageFileType.Wmf;

//Specify the image source as MemoryStream

imageht.ImageInfo.ImageStream = ms;

//Add image object into the Paragraphs collection of the section

sec.Paragraphs.Add(imageht);

//Save the Pdf

pdf1.Save(@"d:\pdffiles\grid.pdf");

// Close the MemoryStream Object

ms.Close();

Please feel free to contact support in case you need any further assistance.
