How to prepare presentations for posting on the STAR websitesThis page is intended to provide guidance to authors who are preparing presentations, typically in Microsoft PowerPoint, for seminars or meetings and eventual posting on the STAR internet website, the STAR intranet, the JCSDA website, or related project sites. We hope to assist you in making a web-friendly and portable presentation file that can be quickly added to websites and can also be e-mailed without overwhelming the file-size constraints for file attachments to e-mail. Requirements for presentation files intended for STAR internet and intranet posting
Using PowerPoint animation featuresFrequently presentation authors use PowerPoint's animation features to overlay one drawing or text object on top of another dynamically. This looks great running through PowerPoint's presentation engine, but be advised that creating a PDF from such files will just stack up all the objects on a page and render them. If you care to prevent this, use separate pages to simulate animation effects, and then the resulting PDF file won't be illegible. Reducing the file size of PowerPoint filesMany presentations developed for STAR seminars contain upwards of 50 slides and are over 10MB saved as native PPT files. One common cause of very large file size is that authors embed high resolution images in their presentations. While desirable for printing, high resolution images aren't necessary for online presentation and viewing. The following technique will help you to reduce the file size of images in the version of your presentation you are sending to STAR for placement on the websites. PowerPoint has a feature that properly reduces the file size and resolution of embedded images to optimize file size while retaining sufficient image quality to render nicely on screen.
Embedded objects from other applicationsMany authors use other applications to create images, charts, maps, and graphs that they then place in their presentation files. How you embed the images, charts, and graphs from other applications into PowerPoint can have ENORMOUS impact on the size of the resulting PowerPoint file. Don't embed graphics into PowerPoint via the clipboardIf you create your charts, graphs, or images in a different application and then copy the content to the clipboard, go to an open PowerPoint file, and then paste the graphic directly onto the page with a Paste or <CTRL>-V command, the resulting files have the potential to be enormous. How big? Sometimes more than 100 MB. This is a big problem. Instead of pasting from the clipboard, IMPORT graphic content into PowerPointIn the program where the graphics you want to use are created, EXPORT the graphics to a standalone file, either vector or bitmap as appropriate. Then go to your open PowerPoint document and select Insert > Picture > From file, and then select your graphic file with the browse tool. More information on optimizing PowerPoint file size:
