Adding GraphicsPath to Bitmap?

[jay]

I have a bitmap and a graphicspath object. I draw pixels on m_Bitmap and I'm
drawing text using m_Graphics GraphicsPath object.

However, saving my work with m_Bitmap.Save doesn't save GraphicsPath along
with it.

How do I save it all in a single file? Or how do I "glue" graphicspath to
bitmap so they save together?

thanks,
jay

If you're intention is to modify a bitmap with graphics in the path then you
need to obtain the Graphics object for the bitmap using Graphics.FromImage,
draw the GraphicsPath to that image using DrawPath or FillPath and then save
the image to a file.

Bitmap bm=Bitmap.FromFile(filename);
Graphics g=Graphics.FromImage(bm);
GraphicsPath pth=new GraphicsPath();
pth.AddEllipse(10,10,200,150);
g.FillPath(Brushes.Yellow,pth);
g.DrawPath(Pens.Black,pth);
g.Dispose();
bm.Save(anotherfilename,ImageFormat.jpeg);

DISCLAIMER: late at night, not compiled, hope you get the picture, (pun
intended)
