[SOLVED] QImage problem - adding/reading path of image with key/text [SOLVED]

Hello, I've written following code:

Code:

---

bool CMerchandizeBrowser::embeddedPicPath(QImage image, QString strFilename)
{
    QImageWriter picImageWriter;    // image key writer
 
    picImageWriter.setFormat(strSupportedFormat);    // sets supported format
    if (picImageWriter.supportsOption(QImageIOHandler::Description))
    {
        qDebug() << strSupportedFormat << " supports embedded text.";
        if (image.text(strKeyImagePathName).isEmpty())
        {
            // pic path has not yet been saved
            image.setText(strKeyImagePathName, strFilename);    // sets embedded text
            return image.save(strFilename, strSupportedFormat);    // saves pic with embedded text
        } else {
            return false;    // path already embedded, abort operation
        }
    } else {
        qDebug() << strSupportedFormat << " does not support embedded text.";
        return false;    // operation failure
    }
    return false;    // operation failure
}

which is responsible to embedd a QImage path into image, but

Code:

---

return image.save(strFilename, strSupportedFormat);

---

returns false. Does anyone has idea why?

Now I thought the chenged picture cannot be written into same filename and I've changed code to:

Code:

---

bool CMerchandizeBrowser::embeddedPicPath(QImage image, QString strFilename)
{
    QImageWriter picImageWriter;    // image key writer
 
    picImageWriter.setFormat(strSupportedFormat);    // sets supported format
    if (picImageWriter.supportsOption(QImageIOHandler::Description))
    {
        qDebug() << strSupportedFormat << " supports embedded text.";
        if (image.text(strKeyImagePathName).isEmpty())
        {
            // pic path has not yet been saved
            image.setText(strKeyImagePathName, strFilename);    // sets embedded text
            strFilename.insert(strFilename.indexOf(strNameExtDelimiter), strFilenameEmbeddedExtendtor);
            qDebug() << "strFilename: " << strFilename;    // debug
            return image.save(strFilename, strSupportedFormat);    // saves pic with embedded text
        } else {
            return false;    // path already embedded, abort operation
        }
    } else {
        qDebug() << strSupportedFormat << " does not support embedded text.";
        return false;    // operation failure
    }
    //return true;    // operation sucess
}

It works now, thank you all anyway!
