[SOLUTION] set UI RectTransform Anchor Presets from code c#
Example of usage solution:
_ImgTransform.SetAnchor(AnchorPresets.TopRight);
_ImgTransform.SetAnchor(AnchorPresets.TopRight,-10,-10);
ImgTransform.SetPivot(PivotPresets.TopRight);
Didn't test, but must to work ok:

Thank you! AnchorPresets. BottomStretch seems to be obsolete preset value, I guess it can be removed. Also no need in Vector3 when assigning anchored position, can do source.anchoredPosition = new Vector2(offsetX, offsetY); ins$$anonymous$$d.
Works like charm. Started writing it from scratch and figured will check if someone has done it already and voila! It saved me an hour or two. Thanks for posting this.
Thanks for it - it was pretty much what I was searching for. I rewrote it a little bit to use DoTween and make a smooth transition instead of instant jump to the new position since that was what I needed.

Wow, what a lot of code to write, do you not use tables? float[] table = new float[]{0,1,0,1,0.5,1,0.5,1,1,1,1,1 ...} int base = allign << 2; source.AnchorMin = new Vector2(table[base++], table[base++]); source.AnchorMax = new Vector2(table[base++], table[base]);
Oops, bad format, try again:
Wow, what a lot of code to write, do you not use tables?
float[] table = new float[]{0,1,0,1,0.5,1,0.5,1,1,1,1,1 ...}
int base = allign << 2;
source.AnchorMin = new Vector2(table[base++], table[base++]);
source.AnchorMax = new Vector2(table[base++], table[base]);
