sp.SaveImage("chart.png",System.Drawing.Imaging.ImageFormat.Png,144);
sp.SaveImage("chart.emf",System.Drawing.Imaging.ImageFormat.Emf);

Overloads

• public void SaveImage(string filename);
• public void SaveImage(string filename,ImageFormat format);
• public void SaveImage(string filename,ImageFormat format,int dpi);
• public void SaveImage(string filename,ImageFormat format,EmfType emftype);
• public void SaveImage(string filename,ImageFormat format,TextRenderingHint textmode);
• public void SaveImage(string filename,ImageFormat format,int dpi,TextRenderingHint textmode);
• public void SaveImage(string filename,ImageFormat format,EmfType emftype,TextRenderingHint textmode);

Description

To prepare an image for publication, you may need a DPI setting of 300-1200 depending on the demands of the repro house. For a chart to be shown on the web, a resolution of 96dpi is generally adequate. The text will be anti-aliased by default, but you may over-ride the text-rendering algorithm by passing in the standard .Net rendering hint as a final option.

For charts saved as Metafiles you may need to experiment with the optimum EmfType parameter. Modern software should read the new GDI+ metafile tags correctly, but older applications may require the old tags as a fallback. The default is to use both forms, but this may make the file larger than you need.
