How to render a graphical volume display in nPVR

[McBainUK]

I'd like to show a progress bar type graphical display to show the current volume as part of my Volume OSD plugin.

I'd like to implement this in nPVR in an efficient and nice looking way. But, graphical stuff has never been my strong point so I'd like to open it up to the group

Any help gratefully received.

I'm at work and haven't got time to edit this, but here's the code I use in the System plugin for drawing, which includes progress bars with gradient paints (cFreeL, cFreeR, etc are Color objects):

Code:

// Return an image for a given drive (name).
public Image GetImage(Hashtable parameters, string name, int width, int height)
{
    // If the request is for "@drvIcon", just return the stored bitmap
    if (images[name] != null)
        return (Image) images[name];

    // If the request is for "@drvRatio, then we need to draw the chart
    if (ratios[name] != null)
    {
        float percent = (float)ratios[name];

        Brush bg = new LinearGradientBrush(new Rectangle(0, 0, width+width/3, height), cFreeL, cFreeR, 45, false);
        Brush fg = new LinearGradientBrush(new Rectangle(0, 0, width+width/3, height), cUsedL, cUsedR, 45, false);                

        Bitmap bitmap = new Bitmap(width, height);
        Graphics g = Graphics.FromImage(bitmap);

        g.FillRectangle(bg, 0, 0, width - 1, height - 1);
        g.FillRectangle(fg, 0, 0, (percent) * (width - 1), height - 1);
        g.DrawRectangle(new Pen(cOutline, 5), 0, 0, width - 1, height - 1);
        g.Dispose();

        return bitmap;
    }

    return null;
}

That looks like a very good start. Thanks.

Out of interest what is 'TimeSharer' referring to in your sig, a holiday apartment search plugin?

Heh. It was my solution to this problem (http://forums.nextpvr.com/showthread.php...g-channels), but I still can't decide whether to make it public or not.
