Jpeg to PDF Conversion in C#

In the following C# programming demo, we will firstly take Jpeg to PDF conversion as an example.

// Define input and output files path.
String inputFilePath = @"***.jpg";
String outputFilePath = @"***.pdf";

// Convert Jpeg to PDF and show conversion result.
ConvertResult result = DocumentConverter.ToDocument(inputFilePath, outputFilePath, FileType.DOC_PDF);
switch (result)
{
        case ConvertResult.NO_ERROR:
                Console.WriteLine("Success");
                break;
        case ConvertResult.FILE_TYPE_UNSUPPORT:
                Console.WriteLine("Fail: can not convert to PDF, file type unsupport");
                break;
        case ConvertResult.FILE_TYPE_UNMATCH:
                Console.WriteLine("Fail: input file is not a document");
        default:
                Console.WriteLine("Fail: unknown error");
                break;
}

Png to PDF Conversion in C#

You may use this demo code in your C# application to implement rapid conversion from Png image to PDF document.

// Define input and output files path.
String inputFilePath = @"***.png";
String outputFilePath = @"***.pdf";

// Convert Jpeg to PDF and show conversion result.
ConvertResult result = DocumentConverter.ToDocument(inputFilePath, outputFilePath, FileType.DOC_PDF);
switch (result)
{
        case ConvertResult.NO_ERROR:
                Console.WriteLine("Success");
                break;
        case ConvertResult.FILE_TYPE_UNSUPPORT:
                Console.WriteLine("Fail: can not convert to PDF, file type unsupport");
                break;
        case ConvertResult.FILE_TYPE_UNMATCH:
                Console.WriteLine("Fail: input file is not a document");
        default:
                Console.WriteLine("Fail: unknown error");
                break;
}

Bmp to PDF Conversion in C#

For converting Bmp image to PDF file, please refer to this C# programming example.

// Define input and output files path.
String inputFilePath = @"***.bmp";
String outputFilePath = @"***.pdf";

// Convert Jpeg to PDF and show conversion result.
ConvertResult result = DocumentConverter.ToDocument(inputFilePath, outputFilePath, FileType.DOC_PDF);
switch (result)
{
        case ConvertResult.NO_ERROR:
                Console.WriteLine("Success");
                break;
        case ConvertResult.FILE_TYPE_UNSUPPORT:
                Console.WriteLine("Fail: can not convert to PDF, file type unsupport");
                break;
        case ConvertResult.FILE_TYPE_UNMATCH:
                Console.WriteLine("Fail: input file is not a document");
        default:
                Console.WriteLine("Fail: unknown error");
                break;
}

Gif to PDF Conversion in C#

Besides Jpeg, Png, and Bmp, C# developers can also render and convert raster image Gif to Adobe PDF document.

// Define input and output files path.
String inputFilePath = @"***.gif";
String outputFilePath = @"***.pdf";

// Convert Jpeg to PDF and show conversion result.
ConvertResult result = DocumentConverter.ToDocument(inputFilePath, outputFilePath, FileType.DOC_PDF);
switch (result)
{
        case ConvertResult.NO_ERROR:
                Console.WriteLine("Success");
                break;
        case ConvertResult.FILE_TYPE_UNSUPPORT:
                Console.WriteLine("Fail: can not convert to PDF, file type unsupport");
                break;
        case ConvertResult.FILE_TYPE_UNMATCH:
                Console.WriteLine("Fail: input file is not a document");
        default:
                Console.WriteLine("Fail: unknown error");
                break;
}
