QPainter drawText on a QImage: Wrong text color???!!!

  • @
    QImage tmpImage = rgb32.convertToFormat(QImage::Format_ARGB32_Premultiplied);

    QPainter painter;
    painter.setPen(fontColor); // The font color comes from user select on a QColorDialog
    painter.setFont(QFont("Chicago", fontSize)); // The font size comes from user input

    rgb32 = tmpImage.convertToFormat(QImage::Format_RGB32);

    Hello everyone :)

    I want to draw a number on a QImage (a series of QImages) fetched from a video sequence. I used the code above.

    The problem is, the text color, which comes from user select, is not printed correctly. For example, the fontColor is Qt::red, but a blue text were printed.

    I also tried other compositionmode, such as

    but nothing changed.

    Can anybody help me?

    Thanks in advanced.

    1. Did you try to draw text on usual image loaded to tmpImage?
    2. Why you use Format_ARGB32_Premultiplied? Video didn't has alpha layer.
