Animated winform idle panel
I am currently writing advanced execution control, 100% open source, and I have created some basic styles with gradients and solid colors.
One option I wanted to add is the animation in the bar, prety is very similar to Windows 7 and the green progress bar. So I need to add a moving "Glow" to% bar, however my attempt at that looks terrible.
My method is to draw an ellipse with the given size and move it to the x position until it reaches the end when the animation starts again.
First, does anyone have any links or code to help me achieve the current window 7 glow effect using GDI or some similar method?
I have a few other animations to be added to the panel as well, so GDI.
private void renderAnimation(PaintEventArgs e)
{
if (this.AnimType == animoptions.Halo)
{
Rectangle rec = e.ClipRectangle;
Rectangle glow = new Rectangle();
//SolidBrush brush = new SolidBrush(Color.FromArgb(100, Color.White));
//int offset = (int)(rec.Width * ((double)Value / Maximum)) - 4;
int offset = (int)(rec.Width / Maximum) * Value;
if (this.animxoffset > offset)
{
this.animxoffset = 0;
}
glow.Height = rec.Height - 4;
if (this.animxoffset + glow.X > offset)
{
glow.Width = offset - (this.animxoffset + 50);
}
else
{
glow.Width = 50;
}
glow.X = this.animxoffset;
LinearGradientBrush brush = new LinearGradientBrush(glow, Color.FromArgb(0, Color.White), Color.FromArgb(100, Color.White), LinearGradientMode.Horizontal);
e.Graphics.FillEllipse(brush, this.animxoffset, 2, glow.Width, glow.Height);
brush.Dispose();
string temp = offset.ToString();
e.Graphics.DrawString(temp + " : " + glow.X.ToString(), DefaultFont, Brushes.Black, 2, 2);
animTimer = new System.Timers.Timer();
animTimer.Interval = 10;
animTimer.Elapsed += new System.Timers.ElapsedEventHandler(t_Elapsed);
animTimer.Start();
}
}
void t_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
this.animTimer.Stop();
this.animxoffset += 2;
Invalidate();
}

This is just an example of a glow repeating across the feather array. You can also use a transparent image (although this can have a performance impact).
Pen[] gradient = { new Pen(Color.FromArgb(255, 200, 200, 255)), new Pen(Color.FromArgb(150, 200, 200, 255)), new Pen(Color.FromArgb(100, 200, 200, 255)) };
int x = 20;
int y = 20;
int sizex = 200;
int sizey = 10;
int value = 25;
//draw progress bar basic outline (position - 1 to compensate for the outline)
e.Graphics.DrawRectangle(Pens.Black, new Rectangle(x-1, y-1, sizex, sizey));
//draw the percentage done
e.Graphics.FillRectangle(Brushes.AliceBlue, new Rectangle(x, y, (sizex/100)*value, sizey));
//to add the glow effect just add lines around the area you want to glow.
for (int i = 0; i < gradient.Length; i++)
{
e.Graphics.DrawRectangle(gradient[i], new Rectangle(x - (i + 1), y - (i + 1), (sizex / 100) * value + (2 * i), sizey + (2 * i)));
}
