I want to achieve a color picker. There are two PNG in screenshot.
The front rectangular icon with arrows is stationary, and back color bar can be moved. Now I use "touch region" and "Displacements" to implement it, but I have no idea how to hide the excess of color bar.
Can Inflexion UI hide one part of PNG?
I can see what you are trying to do here. Inflexion does not allow you hide sections of the PNG. To solve this you would need to implement your design so that front retangular icon with arrows has 'panels' at either end that could be used to hide the excess color bar parts underneath.
Hope this helps.

You mean that the front rectangular icon should be large enough on above to cover the color bar? If so, there is another problem. In each screen, we have a background picture. So the layout from lower z-order is: background -> color bar -> front rectangular region. The background picture can be changed, and the front rectangular region is just on the center and not large enough.
If put the color bar under the background picture, we can not see the color bar.
My understanding is that we can cut the center of background picture to fit the front rectangular icon, and put the color bar under background? Yes, I think this can resolve our problem. But in this opinion, we need to cut every background picture, and need to keep these cut background pictures and original background pictures in flash rom space.
Is my understanding correct? If no other easy method, ok, we can take this.
