Hi Listers,
I have a circle drawn on the monitor screen. I know its diameter and its
centre point in screen pixels.
I want to make sure that text I draw on the screen is completely within this
circle. I use the TextOut function, which uses a POINT sructure for
positioning the text. I can use GetTextExtentPoint32 to calculate the size and
location of the enclosing rectangle of the text. I need to make sure that all
four of the corners of that rectangle are going to fall within the circle.
Can some one please tell me how I can determine the location of the
circumference of the circle, so that I can check that my text rectangle will
fall completely within it? I'm more than 50 years out of high school, and
didn't study mathematics or geometry, or whatever it is that I need, at
university.
Thanks in advance.
Ian
