    Default How to display image with QPixmap from QVector?

    Could someone help me with displaying video from a camera. The values from camera are stored in QVector. Is it possible to display it this way?

    My data is stored in QVector<uint16_t> then i want to scale it to QVector<uint8_t> and into QPixmap class. Or if it's possible directly from QVector<uint16_t> to QPixmap class

    uint16_t is different than uint8_t. You'd have to create a new vector and copy data from the original one. Then you can use QImage::loadFromData() or something similar.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.
