RoundRectangle (Symmetric) William W.
this roundrect function should work in windows 95 paths (WIN95=true)
all the way to the present pretty darn fast comparable to the gdi Roundrect Function and its always symmetrical
since it uses one arc of the ellipse for all the corners
also the number of segments
used to draw the corner can be specified
otherwise they are calculated to be fast yet still good quality
ONE Important Difference:
While the GDI RoundRect is considered a filled shape
This Roundrect fuction does NOT fill the shape drawn
it only frames/outlines the shape if win95= true
You use Polygon instead of polyline
if you desire filled shapes to be drawn but you lose windows 95 path compatibility (WIN95=false)
SEGMENTS
you can overide this by specifying segments when calling this function
otherwise its calculated
Note if you have too few segments it may make shapes non-symmetric
Remember when specifying segments its only for one corner so segments*4
Segments also can define quality from 0-3 above 3 segments and it defines the number of segments used to draw the figure
0=Low, 1=Med Low, 2=Med, 3= High, 4= 4 segments, 5= 5 segments, 6=......
I was looking for info on drawing Round Rectangles really could not find too much that would also work in Windows 95 I tried bezier curves but they were very hard to get perfectly symmetrical results due to the right/Bottom clipping in compatibility mode and frequently the edges were unsightly
so heres my RoundRect that works in Windows 95 paths has customiziable segments and seems to output what the GDI RoundRect outputs but in a higher quality and most times faster try it out let me know if you like it
sorrry to updaye so soon i found a math error that was giving weird results fixed
also added a few things and optmized to the max
compile it and you will really see the difference
