Adding the registry settings

Important: The following steps show 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.

Export a PowerPoint slide as an image file

Start PowerPoint, and then open your slide presentation
Open the slide that you want to export
On the File menu, click Save As
In the Save as type box, select the type of image that you want to export your slide as, and then click Save

For example, in the Save as type box, select one of the following:

JPEG File Interchange Format (*.jpg)
TIFF Tag Image File Format (*.tif)
PNG Portable Network Graphics Format (*.png)
GIF Graphics Interchange Format (.gif)
Device Independent Bitmap (*.bmp)

How to determine the resolution of the image file

With the image file selected in the Windows Explorer,  point to Properties on the File menu, click the Properties, and then click the Summary tab in the pop up Window as shown below

Before adding a registry value, the default resolution for the exported image file is 96 DPI




After adding a registry value, the resolution for the exported image file becomes 300 DPI




Special note:

By changing registry setting allows you to save a PPT slide to an image with 300 DPI resolution, however there is no guarantee if the resolution of originally embedded images in PPT slides is less than 300 DPI. In other words, you CANNOT bump up the image resolution from low to high.

However you will be guaranteed your saved images from PowerPoint have true 300 DPI if the embedded images in PPT slides are vector graphics. All PPT diagrams we developed are vector graphics which allow you to have not only crystal sharp display on the screen, but also publication ready for your paper submission.
