Getting a text or a image from the Linux clipboard and saving it to a file using QT

#include <QApplication>
#include <QClipboard>
#include <QMimeData>
#include <stdio.h>
#include "window.h"

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QClipboard *clipboard = QApplication::clipboard();
    const QMimeData *mimeData = clipboard->mimeData();
    QPixmap pixmap;

    if (clipboard == 0) {
        printf("Error");
        return 1;
    }

    if (mimeData->hasImage()) {
        printf("Found an image. Saving to /tmp/test.ppm\r\n");
        pixmap = qvariant_cast<QPixmap>(mimeData->imageData());
        pixmap.save("/tmp/test.ppm");

    } else if (mimeData->hasText()) {
        printf("Found a text. Writing to stdout\r\n");
        printf("Text: %s\r\n", clipboard->text().toStdString().c_str());
    } else
