Hi Pierre,

Thank you for the feedback.

I am very interested in your method. Could you please provide some more details?

My method is probably very poor, but my goal was to make a circle that could be defined via user input in iziBasic, which would then be sent the parameters to PP and use native API to draw it.

Since PP receives strings from iB (iziBasic), I had to pass the parameters as a string and then let PP cut and convert the string...

Some of the code should probably be changed to the following...

x:=StrAToI(SubString "rect",1,3);

which would be a small bit more efficient (or at least easier to follow when viewing).

The "native" iziBasic method (listed on my site as well) of using the MidPoint Circle Algorithm is a little slower than the PP applet method, but it does allow for hollow circles, in which my method using PP applet certainly did not (looked hollow but weren't :( ). It is terribly slow (too slow for a drawing app) if one has a chance to look at it to and has ideas to speed it up that would be great... maybe I need to dump the routine into a PP applet for speed issues?

If you have any thoughts on speeding up the process of drawing ellipses, as posted a few threads down, that would be great. Unfortunately, I was unable to follow the MidPoint Ellipse Algorithm (just a programmer for a hobby, never took a real class of it) so I had to revert to a meshing of the draw routine and sin/cosine manipulations.

Thanks for taking the time to look at the project. I look forward to any information/assistance that you may provide.

Regards,
bh77a
