    is there a way to get a pixel from a bitmap mask 1-bpp?

    Hi Bas!

    I believe there’s no easy way to do this. You can try asking in the official Qt Forums, they might be able to help you.
    Just an idea: You could have a chance by using a Canvas to draw the image and access the pixel data.




    hi Günther,


    i wanted to show an png image on a background by using slow fade and add some particles for some magical effect.

    i ended up with the following solution: get the center of the content of the png and use a circular random spread.

                    item.x = parImg.x + parImg.px + ( Math.random() * parImg.pradiusX )*Math.cos(angle) - (item.width>>1);
                    item.y = parImg.y + + ( Math.random() * parImg.pradiusY )*Math.sin(angle) - (item.height>>1);


    using the canvas could have been an option 🙂
