upload image knob!!

edited March 2016 in Library Questions

Hello! I presented a doubt in the CP5 library! I need it to load an image on a knob and me is impossible. I am a beginner in processing and I can not solve it! This is for a project and appreciate answers! sorry for my bad English . Cheers!


  • I'm not sure what you are trying to do.

    A knob is what you turn to open a door.

    Maybe you could post your code so we can see what you are attempting?

  • What I try to do is upload an image , a figure like this:


    for different value of the knob there will be a waveform. In this way images appear on the knob ( images sine , triangle , saw , square ) .

    I tried using image ( PImage , x , y) but is plotted under the knob.

    I hope you understand me this time . Sorry for my English

    No matter what you do, the controls are always drawn last so you can't draw over the top of them.

    Ok thank you very much .. do you another question in another discussion as they could not answer me . I need a ShowMessage appears above the program window , as in the following image:


    What I got so far is that the ShowMessage appears under the window. look :


    Need to appear as in the first image, the following code: JOptionPane.showInputDialog("Elija la entrada deseada");

    Thank you !

  • Interesting problem, I assume you are using Processing 3 can you post a short sketch that demonstrates the problem?

  • The only thing I do is write the code posted .. What I do in the void setup () , and since probe . The problem will come from where I place the line of code ?
