Graphical Methodes of the PictureBox Object

I use a filling algorithm along with the point and pset methods of the picturebox to fill or mask shapes contained in a bitmap like a tree or a house
this way seems to be rather slow
is there any other way which enabels me to perform graphical analysis and changes to a bitmap rather than pset
, point methods

Take a look at the FloodFill and ExtFloodFill API's. What they do is (quickly) fill an area (in a device context) which is defined by a single boundary color. Here is an example of using FloodFill to fill a triangle:

' Place the following code in the declarations section of the form.
Private Declare Sub FloodFill Lib "GDI32" Alias "FloodFill" _
(ByVal hDC As Long, ByVal X As Long, ByVal Y As _
Long, ByVal crColor As Long) As Long

Private Sub Form_Click ()
ScaleMode = vbPixels ' Windows draws in pixels.
ForeColor = vbBlack ' Set draw line to black.
Line (100, 50)-(300, 50) ' Draw a triangle.
Line -(200, 200)
Line -(100, 50)
FillStyle = vbFSSolid ' Set FillStyle to solid.
FillColor = RGB(128, 128, 255) ' Set FillColor.
' Call Windows API to fill.
FloodFill hDC, 200, 100, ForeColor
End Sub
