UP!

I've found two things:

- Using

1. pixels[y*width+x]

I can get pixel color in screen but without take care of different image which composes scene. After getting pixel color i can determine which button was clicked BUT
      - i can't hide the color image, color which are detected with pixels[] must be in the visible image.
      - if there are some text in front of button color, pixels[] will get text color instead of button one.
      - i can't use two button with same color or they will display the same event.

Good point is that with this method i can moove and rotate my image and still getting good pixel color.

- Second method using

1. imageColor.get(x,y)
2. imageColor1.get(x,y)
   

I can get pixel color of each image which composes scene. I can differentiate each image so i can use same color on different image because i target one image file before getting it's pixel color. I can hide my imageColor and just display the image that must be saw BUT
      - i can't move or rotate my images, they were fixed at 0,0 where the loadImage() load the image. If i try to use Matrix or (method) image(imageColor, 100, 100, imageWidth, imageHeight), the get(x,y) method will continue to take care of loadImage() and process with 0,0 origin and not 100,100.
      - i can't move or rotate my images so i must work with a full screen image(s).
      - i can't make moving or rotating button, all inter-active image button must be static.

What i would like obtain:

A system which allow to move or rotate my (complexe) button (not rectangle or circle) and continue to get the good pixel color in order to derterminate which button just be clicked.

Ok, thx for your help.

Now my problem is, i try to use G4P but:

1.         String[] files;
2.         files = new String[] {
3.                 "coins0.png", "coins1.png", "coins2.png"
4.               };
5.          btnCoins = new GImageButton(parent, 400, 20, files);

make this error, and i dont understant what i'm doing wrong.
