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.
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

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.
