Conversion

Convert Image to PDF and embed metadata

Convert a JPEG image to a PDF document. Set the XMP metadata of the PDF document based on a conforming XMP file, which contains information such as author, title and creator.

C# sample:

// Create the converter
using (Img2Pdf converter = new Img2Pdf())
{
    // Create output file
    if (!converter.Create(outPath, "", "", PDFPermission.ePermNoEncryption))
        throw new Exception(String.Format("Output file {0} cannot be created. {1} " +
            "(ErrorCode: 0x{2:x})", outPath, converter.ErrorMessage, converter.ErrorCode));

    // Set xmp metadata
    converter.SetMetadata(metaFile);

    // Convert pages from input image to PDF
    if (!converter.CreatePageFromImage(inPath))
        throw new Exception(String.Format("Pages cannot be created from image input {0}. " +
            "{1} (ErrorCode: 0x{2:x})", inPath, converter.ErrorMessage, converter.ErrorCode));

    // Close output file
    if (!converter.Close())
        throw new Exception(String.Format("Output file {0} cannot be closed. " +
            "{1} (ErrorCode: 0x{2:x})", outPath, converter.ErrorMessage, converter.ErrorCode));
