Aspose.Page for .NET EPS Merger allows to merge Encapsulated PostScript (EPS) files to PDF document with using of any language supported by .NET platform: C#, VB, J#.
To merge EPS files into a single PDF, follow these steps:

1. Create a PsDocument instance by passing the path of the first EPS file to its constructor, which loads the EPS content for merging.
2. Define a string array containing the file paths of the additional EPS files to be merged, e.g., string[] epsFiles = { "second.eps", "third.eps" };.
3. Instantiate PdfSaveOptions, set AdditionalFontsFolder to the folder with custom fonts, and optionally set SuppressError = true to collect non‑critical errors.
4. Call document.AddPage(epsFiles); (or use the appropriate merge method) and then document.Save("merged.pdf", pdfSaveOptions); to produce a single PDF.
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 EPS files to PDF document in C#:

// Merge several EPS files to one PDF document.

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

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

// 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);
    }
}

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

• Size specifies the size of the pages in resulting document.
• AdditionalFontsFolder specifies locations where to find fonts. System fonts folders are always included by default.
• SuppressError controls behaviour of EPS 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.
