[OpenLayer] A few bugs

[OpenLayer] A few bugs

Hi,

First I would like to say that OpenLayer is the best library that I've ever used.

But I've found what I think is bugs (using the latest snapshot ofcourse).

1) "Ellipse" is not in "ol::" namespace, you have to use ol::Ellipse currently.

2) Ellipse: Impossible to set outline width higher than 1.0. Else the shape move very fast in diagonal and disapear (ex: ol::Ellipse ellipse(200.0,200.0,100.0,60.0,2.0);

3) TextRenderer: Print() with CENTER mode for multi-lines strings slows down the game by 75% (!!). No effect on fps with a single line...

4) Anti-Aliasing: With my Gfx Card (GeForce Go 6200), I get strange results, commented on the screenshots:
{"name":"aliasing7bs.png","src":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/9\/3\/9312a958d1da87cab2f62114a2e293d6.png","w":664,"h":124,"tn":"\/\/djungxnpq2nug.cloudfront.net\/image\/cache\/9\/3\/9312a958d1da87cab2f62114a2e293d6"}

So antialiasing works for Bitmap(), but not for the Shape(). However if I force antialiasing with the card settings (instead of leaving the app control it), it works... So it's probably something missing in the OL code.

That's all for now (we really need an OL part in those forums )

Thanks

I'm not sure why you are having these problems. Fladimir doesn't seem to be around at the moment either. Perhaps someone else can help?

That's probably because OL uses fsaa, which is a hardware routine (I don't think GL supports a software routine)

---Allegro Version 4.2.0 (beta4)
The hardest part is getting started.

ummmm.. Ellipse IS in the ol namespace.
Also you must define an outlinewidth between 0.0 - 1.0 otherwise it's not going to work... it defaults to 1.0

character.cpp:257: error: `Ellipse' undeclared (first use this function)
character.cpp:257: error: (Each undeclared identifier is reported only once for each function it appears in.)

ol::Ellipse fix the problem.
I have no problem with Rect or any other OL class. ("using namespace ol" ofc)

For rectangle or Poly you can use wider outline width than 1.0 (wich is a good thing). Why limit it with Ellipses ? (and it should not bug like that if 1.0 is the maximum)

Me is working on something that runs just fine on my computer.
But on other computers it crashes.

Guilt has gotten this from debug.
We've decided to blame OpenLayer for the crash.
