Drag and drop : How to zoom ?

noé cambou

hi :D
Do you know how can i zoom in my game ? i would try to make a zoom as many other games (such as clash of clan, garden scapes etc...). With 2 fingers which are going to extremities of the screen.
Do you know if i can make it easily with free version of Gamemaker or if i have to pay Android version for example ?

Thank you very much :D
