Why is it not giving you the right results? CalculatePrintedSize is for text. CalculateRelativeWidgetBounds is all you need. Specify the panel as the root for that function.
Use UITexture to display non-atlased images.
ah it appears I was making a mistake in my own calculations

, it works.
About the UITexture, It appears my clipping doesnt work on it.
I want to use it as image to zoom into, with clipping...
Is there a way around this?
******edit: nevermind, I shouldn't post before really trying myself

Ok one more question then:
I changed the shader in order to get the clipping on the UITexture.
However, I assign textures to it from another scipt, with texture2D.
I can see the textures switching correctly in the UITexture, but somehow the image wont update during a play test..?
