2ton,
try this link http://unurbandictionary.comule.com/polygon_large/
I made it detect a larger area(twice the regular size) to join/close off shapes.
See if it's easier and let me know

Molly, you have an ipad mini, maybe you can try that link too?

I am trying it out. I can see that the points are larger but they are just sitting there and not making the closed connection into a polygon.

OOps, there is goes. I was tapping all over and all of a sudden a triangle appeared.

getting points to make a polygon is either random or incredibly slow on the tablet. I can only make triangles, but that is ok. Sometimes when I make the polygon points it will work, other times it just makes the little point but no polygon is made. I have no idea why as there doesn't seem to be any sort of pattern to how it happens.

an observation…there seems to be a bit of conflict between the regular touch commands built into the iPad and the touch being used as a mouse click. For instance, when you try to move a point, you often end up also scrolling the picture as you move the point. However, having larger points is helpful, and a great improvement.

yeah moving the point scroll the page i read about that and there didn't seem to be a good solution around that since we're trying to simulate the mouse.

It is not really that big of a problem. The worse thing is that the polygons appearing seems so random.

2ton,

try http://unurbandictionary.comule.com/polygon_large/ again.
I added 3 new links (it's defaulted to 3 points at start)
3 points
4 points
5 points
So if you want to draw triangles just click on 3 points you don't have to close it off, it'll auto close.
But if you plan to do a 4 sided polygon just click on 4 points and it'll set to auto close after you click 4 points
and the same for 5 points.

Try it out and let me know if this is an improvement since you don't have to try to close off the polygon but it auto-closes after a number of specified points.

according to 2 ton (through a series of private messages).
http://unurbandictionary.comule.com/polygon_test/ works great on ipad

I finally got this sent to my computer to post. Of course, it's not a great pic, but my tablet is a mini and I was using my fat fingers. What is exciting is that it worked quite easily, you can choose your pic file, you can choose the shape of each polygon, you can move vertices without scrolling accidentally. Trandoductin did an amazing job of changing the code many times to find a way to make it work. I can't say about saving it, I didn't even try, I just took a screen shot. I need to test with a picture that the other versions would not work on, and then test on how I can save it to the iPad. I have not had so much time recently, but hopefully soon can do this. *sorry it's sideways, that's the was it comes up on the iPad.

2 ton,
try this
if you click on 5 points link then instead of picking 5 points, try picking 3 points and then click on the 1st point to manually close triangle see if that works. This works with a mouse. So if you tell it to auto-close after 5 points, you can still do triangles by manually clicking on first point without having to click 3 points link.

yup, it works fine! I have misplace the stylus, so I can't try to make a good pic until I relocate it. But all is working great! It saves as svg just fine, but I have to find out how to save it as a jpg…the iOS way is sometimes different that osx.

so closing polygons manually works too? I didn't expect that.

It works very well now. Great little program to play with on a tablet!
