Draw area from BGRA to BGRA

[circular]

Hello bigeno,

I've optimized polygon drawing. I applied the modification you proposed about not adding duplicate points, and also rewrote TBGRAFillInfo : now there is TOnePassFillPolyInfo which is twice as fast.

It's on subversion.

hm, something is wrong with EmptyPoints. I get Range Check Error in bgrafillinfo.pas under TOnePassFillPolyInfo.Create.
Line 1029 with

Code: [Select]

p^.next := @FOnePass[FNext[i]];
//when FNext[i] = -1

when I disable Range Check Error I get AV in bgrapolygon.pas. Line 780

Ok thanks. I've solved the problem. I'm also preparing a benchmark. Please wait.

Done. It's updated on subversion. And here is a benchmark :

well done
but still ther is a problem with PolygonF. If you draw with bmp.CanvasBGRA.PolygonF(poly,true) instead FillShape then will crash.

Thanks.

Oh well yes I forgot that multishape filler changes the intersection array, so that it must create intersection array if necessary. That should be fixed.

Well spotted
