I want to draw a circle with center {x,y} in an image. I use the following code:
img = Image[Graphics[{
{Red, Thick, Circle[{100, 200}, 20]},
{Opacity[0, Black],Rectangle[{0, 0}, {500, 500}]}
},
ImageSize -> {500, 500}],ColorSpace -> "RGB"]
What I don't understand is that if I print the Image to the screen the position of the circle is not as expected. As you can see {100,200} is not the center of the circle.
How could I print a circle with the right coordinates?
