How to render 64x64 px image as 32x32 px on ttoolbutton

[KingOrmon]

Hello,

 

I am playing with retina icons. I see that if use <img src="my64px.png" witdh="32px" height="32px"> icons are smoothly drawed.

 

I would like use a hack of TUniImagelist that allow insert 64 px or larger image and render as 32px for example.

 

Any solution ?
