Bad rounded corners, its a bug or its me?

[joejac]

Hello,

I spent countless hours with this:

I draw a shape with the Standard Shape Tool - Draw Rounded rectangle
I select in Shape Properties - Look - Line width either 0.25, 0.5 or 1 I play the movie and the button shape has an awful rounded corners drawn. For line width of 2 it is better but for 3 is bad again, and I need 0.25 width, can some body explain this behavior to me, please?

I do not want to go to an Image vector program to draw my buttons, export and import into Koolmoves. Please help me with this to find what its going on with the rounded corner inside Koolmoves.

By the way I did a search in this forum for "round corners" and I noticed that links to examples and tutorials are broken.

I would suggest a Koolmoves place for the documentation and all the nice tutorials to be posted there and preserved in time.

Your kind help it is very much appreciated.

regards
joejac

There is such a place http://koolexchange.com

I'm not sure what's going on with your shapes I'll look a bit.

Bret, the tool for rectangles with rounded corners does not give a smooth line, I notice most often it is worse on the bottom corners.

Interesting, I hadn't noticed this before but you seem to be right.
It seems to be an issue with the number of rounded nodes. I tried drawing one in another program and bringing it in as an SVG (which works pretty well for simple shapes) and noticed many more nodes in the corners which looked much better.

I had metioned this sometime back. I either set the line to 0 or used transparency for the line. But looking at Bret's svg import image, I'll have to try that.

That rectangle was done in Realdraw from http://Mediachance.com

Didn't get good results from Inkscape

Thanks Bret!

I suspect it is a pixel round off problem. You might try nudging the bad points.

I am not sure only what conditions fractional widths work but it is definitely not screen display.

Not sure I understand Bob, but what I'm seeing looks like it's that the individual line segments making up the rounded corner are just too big. In the SVG it's still there made up of straigt lines but notice there are 4 curve points and 5 fixed points compared to 1 round and 2 fixed in the KM drawn corner. Seems to me this might be something that could be improved upon.

[Bob Hartzell]

Are you saying that there aren't enough corner points to handle the roundedness?

[Stoke Laurie]

Thats absolutly the case Bret, the appearance will better, the greater the number of nodes. Flash mx and above allows the user to select the number, so thats one possible fix route. In the meantime, something that does work well is to create a regular rectangle, then apply the curved line option to both of the short sides, this creates an acceptable long oval with straight top and bottom.

Hello gentlemen,

I am a little confused here, isn't Koolmoves a vector graphics program? I do not understand much on the issue but as far as I know vector graphics are based on mathematical equations to draw images, so for this reason the drawings are continuous and smooth in contrast with bitmap programs. If so, probably the equation used inside KM to draw curves needs to be checked by your programmer.

I have KM V 5.7.6

Any help it is very much appreciated.

Vector drawings are based on points, not mathematical equations. Curves are dependent upon how many points define the curve.
