Splash screen

  • 12 years ago

    Hello,

    I am new to VB.NET since September 2006.

    I have a project that requires to create the code for two traingles with a graduated color scheme in a splash screen form. Hint: These triangles were created by drawing successibely shorter lines and varying the color for each line drawn. The top triangle varies the green value from 0 to 255. The red and blue values are zero. The lower-right triangle was created by varing the blue from 255 to 0. The red and green values are 0.

    I do not know how to create these triangles. I need your help.

    Many thanks.

    Are you required to create the triangles using code or can you just create an image in another program and use that for your splash screen?

    I am required to write codes to create two triangles with a graduated color scheme.

    Sorry for the confusion.

    Here is a little code and info that might help out a little.
        Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
            'An array of points that defines a triangle
            Dim points(2) As Point
            'An image the size of the form
            Dim bmp As New Bitmap(Me.ClientSize.Width, Me.ClientSize.Height)
            'A graphics object to do the drawing
            Dim gr As Graphics = Graphics.FromImage(bmp)
    
            'Bottom left point
            points(0) = New Point(0, bmp.Height)
            'Bottom right point
            points(1) = New Point(bmp.Width, bmp.Height)
            'Top middle point
            points(2) = New Point(CInt(bmp.Width / 2), 0)
    
            'Use AntiAliasing to create smoother edges
            gr.SmoothingMode = Drawing2D.SmoothingMode.AntiAlias
    
            'Fill a polygon defined by the points array and filled with blue
            gr.FillPolygon(Brushes.Blue, points)
            'Clean up
            gr.Dispose()
    
            'Set the forms background image to our triangle
            Me.BackgroundImage = bmp
    
            'I don't know much about creating gradients but I know you can create
            'gradient brushes using:
            'System.Drawing.Drawing2D.LinearGradientBrush()
            'System.Drawing.Drawing2D.PathGradientBrush()
            'Hopefully this will get you started.
        End Sub
