user18258: What is the best way to position the anchor point in the exact center of the smaller circle of this PNG figure?
My methods were all manual and in this way I did not have good results.


user20110: You can create a different file by filling in the desired region in red.

Go to website: WOLFRAM DEVELOPMENT PLATFORM
And enter the code below:
image=Import["C:\\Users\\Image.png"]
value={ImageDimensions[image]}-{Mean[ImageValuePositions[image,Red][[All,#]]]&/@{1,2}}


Enter the values offered for the anchor point. In this case: 386.995 and 173.982
