Subject: Filling in a rectangle with colors

I am trying to put three colors into a rectangle, but it is not working as I "think it should".


procedure TForm1.CreateNewImage(const Path2Image : ShortString);
jpeg1 : TJpegImage;
bitmap2 : TBitMap;
i, j : Integer;
ForeRow: pRGBTripleArray;
// Let's see if I can color a rectangle.
// If that works, then I'll try painting a
// border
BitMap2 := TBitMap.Create;
BitMap2.Width := 150;
BitMap2.Height := 100;
for i := 0 to BitMap2.Height - 1 do begin
ForeRow := Bitmap2.ScanLine[i];
for j := 0 to Bitmap2.Width - 1 do
ForeRow[j].rgbtBlue := 100; // We will try using 100
ForeRow[j].rgbtRed := 100;
ForeRow[j].rgbtGreen := 100;
end; {for i}

bitmap2.SaveToFile(ProgPath + 'Painted.bmp');
