Tile image as background

[lainz]

BTW I've added a new property 'Tile' in BGRASpriteAnimation in the git repository of BGRAControls.

That's right Lainz, you can use GetPart.

You can also use the Fill method. Instead of writing

Code: [Select]

var
  tile: TBGRABitmap;
begin
  tile := background.GetPart(rect(0,0,Width,Height)) as TBGRABitmap;
  Bitmap.PutImage(0,0,tile,dmSet);
  tile.Free;
end;
You can write

Code: [Select]

begin
  Bitmap.Fill(background);
end;

I can fill transparent bitmap?

[circular]

Of course, with FillTransparent method.

My question is if I can fill a bitmap with transparent area with Bitmap1.Fill(Bitmap2); (bitmap2 has alpha pixels);

You can add procedure TBGRADefaultBitmap.Fill(texture: IBGRAScanner);   with a new option transparent: boolean, or drawmode: TDrawMode;

Ah ok, you mean when there are alpha pixels, they are blended and you would like to use dmSet mode instead ?

They aren't blended with Fill(bitmap) because by default is dmSet in:

Code: [Select]

procedure TBGRADefaultBitmap.Fill(texture: IBGRAScanner);
begin
  FillRect(FClipRect.Left,FClipRect.Top,FClipRect.Right,FClipRect.Bottom,texture,dmSet);
end;   
BTW I've solved the problem using FillRect.

Code: [Select]

battleroom.FillRect(0, 0, battleroom.Width, battleroom.Height, grid, dmDrawWithTransparency); 

[circular]

Ok. I've added Fill(IBGRAScanner, TDrawMode) on subversion
