What were you trying to do?

I tried to take an image from a read node and center it to the image via a transform node. In my case, HD Format 1920px, so I put in 960px in x.

What did you expect to happen? What happened instead?

The transform node puts the image off center by the half value of the images width. If I reset the center on the transform node and minus that value from the translate value, the image appears to be at the right position.

I think the transform node does not take the center of the image into account and uses the x0y0 origin of the image instead.

Step-by-step reproduction instructions

1. load image via read node
2. add a transform to half the size of your canvas size
3. the image is off
4. press reset center if your transform is not at the middle already
5. minus that value with the translate x value
6. the image is at the right location
