Aspose.Page for .NET PS Merger allows to merge PostScript (PS) files to PDF document with using of any language supported by .NET platform: C#, VB, J#.
It is necessary to do several steps in order to perform PS merge:

1. Initialise a PsDocument with the primary PS file, e.g., var document = new PsDocument("first.ps");.
2. Define a string array containing the paths of the additional PS files to merge, for example:

   string[] additionalPs = { "second.ps", "third.ps" };

3. Create a PdfSaveOptions instance, optionally set AdditionalFontsFolder and enable SuppressError = true to capture non‑critical warnings.
4. Add each additional PS file to the document (e.g., foreach (var file in additionalPs) document.AddPage(file);) and then save the merged PDF:

   document.Save("merged.pdf", pdfSaveOptions);

5. When SuppressError is true, any warnings are stored in document.Exceptions; you can iterate this collection after saving to review the issues.

The following code snippet shows how to merge PS files to PDF document in C#:

// Merge several PS files to one PDF document.

// Initialize PS document with the first PostScript file
PsDocument document = new PsDocument(DataDir + "input.ps");

// Create an array of PostScript files that will be merged with the first one
string[] filesForMerge = new string[] { DataDir + "input2.ps", DataDir + "input3.ps" };

// If you want to convert Postscript file despite of minor errors set this flag
bool suppressErrors = true;

//Initialize options object with necessary parameters.
PdfSaveOptions options = new PdfSaveOptions(suppressErrors);
// If you want to add special folder where fonts are stored. Default fonts folder in OS is always included.
options.AdditionalFontsFolders = new string[] { @"{FONT_FOLDER}" };

// Default page size is 595x842 and it is not mandatory to set it in SaveOptions
// But if you need to specify the page size following line
//PdfSaveOptions options = new PdfSaveOptions(suppressErrors, new Aspose.Page.Drawing.Size(595, 842));

document.MergeToPdf(OutputDir + "outputPDF_out.pdf", filesForMerge, options);

//Review errors
if (suppressErrors)
{
    foreach (Exception ex in options.Exceptions)
    {
        Console.WriteLine(ex.Message);
    }
}

See PS merge in Java and C++.

Let’s consider PdfSaveOptions. Using this class we can assign different conversion parameters while merging PS files to PDF.

• AdditionalFontsFolder specifies locations where to find fonts. System fonts folders are always included by default.
• SuppressError controls behaviour of PS merger when non-critical errors are appeared. If value is true than it is possible to view a list of such errors after merging in Exceptions field. Default value is true.
• Debug allows outputting debug information to console. Default value is false.
