AFAIK Expand from centre is for mouse moves only. The position/size fields in the tool options are always for top-left corner and complete size. Note that you can do some arithmetic in these fields, for instance in a 400x300 image you can do create a 200x100 centered selection with by entering:
When you strike [enter] Gimp does the computation and shows the result in the field.
In other words, Xcenter-(Xsize/2)), YCenter-(YSize/2).
Code:
Position
(400/2)-(200/2) and (300/2)-(100/2)
Size
200 and 100When you strike [enter] Gimp does the computation and shows the result in the field.
In other words, Xcenter-(Xsize/2)), YCenter-(YSize/2).
