Canvas->FloodFill operation
I have used in my component: Canvas->FloodFill method
(under C++Builder5 with Win98)
for filling about 200 fields (about 4/4 pixels) in my application.
It was working pretty good.
Now I'm using C++Builder6 on WinXP
and it appears to be very slow!!! is there something changed since
C++Builder5 ???
I think it slowing down about 100 times. :(
My code is as is:
int x, y, iField,
for (iField=0; iField<=200; iField++ )
{
x = GetFieldPositionX(iField); // My function, that returns each
field x position
y = GetFieldPositionY(iField); // My function, that returns each
field y position
Canvas->Brush->Color = clBlack;
Canvas->FloodFill(x, y, clWhite, fsSurface);
}
My fields are not rectangles, but:
for test purposes I have tried FillRect method instead FloodFill,
and the speed is pretty good for me.
Canvas->FillRect(Rect(xc,y,xc+4,y+4));
Why Canvas->FloodFill is so slow here, and how to make it faster?
(while my areas to fill are not rectangular).
Help please.
