I use an TImageEnView.
When i set the image to be centered inside imageview i would like to get cursor x,y in relation to the beginning of the image, not the beginning of imageenview.
Which parameter can i use to substract the distance of
imageenview.left / top
and
imageenview.iebitmap.left / top

I hope you understand of what i´m speaking of.

You can also use XScr2Bmp and YScr2Bmp, which take care of zoom and pan:

BitmapX := ImageEnView.XScr2Bmp(componentX);
BitmapY := ImageEnView.YScr2Bmp(componentY);
