Postscript to PDF Conversion Results In Blank Document

Aspose.PDF Product Family
1

I’m interested in converting a postscript file, built from an outside process, into both PDF and HTML formats. I’ve followed all examples that I can find on the forums here and StackOverflow but result in a blank PDF document or blank HTML document each time.

I can provide code samples if needed but am primarily following this one:

I’m currently using a temporary license and an wondering if that is the issue? Any and all pointers greatly appreciated.

Would you please share your sample source file(s) for our reference which you are trying to convert into PDF? We will test the scenario in our environment and address it accordingly.

Current code is posted here. This is basically what is shown in the example that I attached in the OP.

FileStream inputStream = new FileStream(qualifiedPsFileName, FileMode.Open, FileAccess.Read);
PsDocument psDocument = new PsDocument(inputStream);

FileStream outputStream = new FileStream(qualifiedPdfFileName, FileMode.Create, FileAccess.Write);
PdfDevice pdfDevice = new PdfDevice(outputStream);
Aspose.Page.EPS.Device.PdfSaveOptions pdfSaveOptions = new Aspose.Page.EPS.Device.PdfSaveOptions()
{
	SupressErrors = false,
	Debug = false
};

PdfDocument pdfDocument = new PdfDocument();
pdfDocument.Save(outputStream);

Here’s a typical PS file that should easily convert to PDF:

It looks like you have obtained the license for Aspose.PDF but in your code, you are using Aspose.Page. I order to convert Postscript file into PDF using Aspose.PDF, please use following code snippet:

string inFile = dataDir + "demo.ps";
string outFile = dataDir + "PStoPDF.pdf";
Document doc = new Document(inFile, new PsLoadOptions() { FontsFolders = new[] { "C:\\Windows\\Fonts" } });
doc.Save(outFile);

Also, please check below files generated in our environment.
