Add the Registry Settings

To export a slide as a picture with a resolution greater than the default 96 dpi, you must add a registry value. To do this, follow these steps.

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

1. Quit your Microsoft Windows programs.
2. Click Start, and then click Run.
3. In the Open box, type regedit, and then click OK.
4. Expand the registry to the following key:

   HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\PowerPoint\Options

5. With the Options key selected, point to New on the Edit menu, and then click DWORD Value.
6. Type ExportBitmapResolution, and then press ENTER.
7. With ExportBitmapResolution selected, click Modify on the Edit menu.
8. In the Value data box, type the resolution value that you want, based on the following table.
   
   Note The maximum resolution setting that PowerPoint 2003 exports is 307 dpi.
   
   

   Decimal value	Pixels (horizontal x vertical)	Dots-per-inch (horizontal and vertical)
   50	500 x 375	50 dpi
   96 (default)	960 x 720	96 dpi
   100	1000 x 750	100 dpi

Limitations

When you set the ExportBitmapResolution registry value in the registry to change the export resolution of a picture in Microsoft Office PowerPoint 2003, there is a limitation that you must be aware of. The maximum resolution setting that Office PowerPoint 2003 exports is 3072 pixels measured from the longest edge of the slide. For Example, the standard 10x7.5" slide would have a maximum effective DPI value of 307. (10x307) = 3070. The measurement of 3070 pixels falls within the 3072 limit. Any DPI settings higher than 307 for the standard slide would revert to the limit of 3072.

Decimal value	Pixels (horizontal x vertical)	Dots-per-inch (horizontal and vertical)
307	3072 x 2304	307 dpi

Note The limitation of 3072 pixels applies to programmatically saving the slide as well. Code that is designed to export the slide at a given pixel measurement will also be limited to 3072 pixels. For example, ActiveWindow.Selection.SlideRange(1).export "c:\filename.jpg","JPG",4000,3000 will result in a graphic being programmatically exported at 3072x2304 pixels.
