> @alisenchung  I tried by increasing and decreasing the line position a bit, the current combination provided optimal positioning of both the shadow and highlight line within the border for all the scales. The slight inconsistency in spacing is probably due to rounding losses in loop count, stroke width and corner. I'll check it again.

Oh, I meant the actual code spacing, theres a space between scaledCorner and 1, but not space between midPoint and stkWidth
