PDF File Encoding to Base64

See more Base64 Examples

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

#include <CkBinDataW.h>

void ChilkatSample(void)
    {
    bool success = false;

    CkBinDataW pdfData;

    success = pdfData.LoadFile(L"qa_data/helloWorld.pdf");
    if (success != true) {
        wprintf(L"failed to load PDF file.\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 wchar_t *b64 = pdfData.getEncoded(L"base64");
    wprintf(L"%s\n",b64);

    // Decode from base64 PDF.
    CkBinDataW pdfData2;
    pdfData2.AppendEncoded(b64,L"base64");
    success = pdfData2.WriteFile(L"qa_output/helloWorld2.pdf");
    if (success != true) {
        wprintf(L"failed to write PDF file.\n");
        return;
    }
    }
