PDF Converter til .NET

Introduktion til PDF Converter for .NET

PDF Converter for .NET er en kraftfuld plugin, der gør det muligt for udviklere at konvertere forskellige filformater til PDF-dokumenter. Denne guide giver en oversigt over de tilgængelige funktioner, sammen med kode eksempler i C# for at få dig startet.

Konvertering af Excel-filer til PDF

To convert Excel files to PDF, you can use the Aspose.Cells namespace. Here’s a simple example:

using Aspose.Cells;

// Load the Excel file
Workbook workbook = new Workbook("example.xlsx");

// Convert the Excel file to PDF
workbook.Save("output.pdf", SaveFormat.Pdf);

In this example, we load an Excel file using the Workbook class and then save it as a PDF file using the Save method.

Konverter billeder til PDF

To convert images to PDF, you can use the System.Drawing namespace in conjunction with Aspose.CellsHer er et eksempel:

using System.Drawing;
using Aspose.Cells;

// Create a new workbook
Workbook workbook = new Workbook();

// Add the image to the workbook
Worksheet worksheet = workbook.Worksheets.Add();
worksheet.Pictures.Add(1, 1, "image.png");

// Convert the workbook to PDF
workbook.Save("output.pdf", SaveFormat.Pdf);

I dette eksempel lader vi en billedfil op og tilføjer den til en ny arbejdsbok, og gemmer derefter arbejdet som en PDF-fil.

Tilpasning af PDF-udgang

You can customize the PDF output by using various options provided by the PdfSaveOptions class. For example:

using Aspose.Cells;

// Load the Excel file
Workbook workbook = new Workbook("example.xlsx");

// Create a new PdfSaveOptions object
PdfSaveOptions options = new PdfSaveOptions();

// Set the PDF compression
options.PdfCompression = PdfCompressionCore.Flate;

// Set the compliance level to PDF/A-1b
options.Compliance = PdfCompliance.PdfA1b;

// Convert the Excel file to PDF with custom options
workbook.Save("output.pdf", options);

In this example, we create a new PdfSaveOptions object and set the compression and compliance. We then pass this object to the Save method to convert the Excel file to PDF with custom options.
