2d transform/scale around set center?

Question

How can I do a something like 2d transform which would allow to scale something around a center of transform? Not just left or right?

And do it not 0,5 or 1,5 but rather exactly to 55 x 1500 pixels for example ?

Does anyone ever tried to make such a node?

I hate 2d transform , It's so monstrously inconvenient and blurry . Any image editor starting dfrom Photoshop have this feature for decades.

Is there any way to make your own transform gizmo that would have those features?

Oops - sorry, I misread your post. Why not have two for the price of one &#128578;This one should both rotate and scale around a chosen point Pixel processor function :  Dave

You could use the pixel processor and feed it inputs for rotation and rotation centre.

In the pixel processor function below I've just used 0 to 1 for rotation and 0,0 to 1,1 for centre position (0,0 is top left). You could add a little more math to calculate the centre as a pixel based position based on $size.

Make sure you set the Sample Gray node in the pixel processor to to bilinear filtering mode
