PDF File Encoding to Base64

See more Base64 Examples

Demonstrates how to encode a PDF file to base64, and then decode. C++

#include <CkBinData.h>

void ChilkatSample(void)
    {
    bool success = false;

    CkBinData pdfData;

    success = pdfData.LoadFile("qa_data/helloWorld.pdf");
    if (success != true) {
        std::cout << "failed to load PDF file." << "\r\n";
        return;
    }

    // Encode the PDF to base64
    // Note: to produce base64 on multiple lines (as it would appear in the MIME of an email),
    // pass the string "base64_mime" instead of "base64".
    const char *b64 = pdfData.getEncoded("base64");
    std::cout << b64 << "\r\n";

    // Decode from base64 PDF.
    CkBinData pdfData2;
    pdfData2.AppendEncoded(b64,"base64");
    success = pdfData2.WriteFile("qa_output/helloWorld2.pdf");
    if (success != true) {
        std::cout << "failed to write PDF file." << "\r\n";
        return;
    }
    }
