We appreciate your contribution to one of our largest educational forums. Thanks to your participation, we have expanded our vision to create the new Wolfram Community, which will bring together members of our entire global family. With the launch of the new Wolfram Community, the Wolfram Faculty Program Forum will be retired on August 6, 2013.
We encourage all members of the Wolfram Faculty Program Forum to join Wolfram Community. Sign in with your Wolfram ID at http://community.wolfram.com to get started.
Wolfram Community features discussion groups for all Wolfram products as well as topic-based groups like education, chemistry, and geometry.
And don't worry: all discussions on the Faculty Forum will be preserved for reference. We're simply switching this site over to read-only mode as we work to bring the entire Wolfram Community together for learning, sharing, and collaborating.
1. When I drag in or paste a PDF — my preferred graphics format — into an Apple iWork document, it scales beautifully when a user changes the magnification of the document. This is also true when I save the document as PDF using Preview. I notice, however, that when I paste or import a PDF into Mathematica, the image is fine at actual size but if the document is magnified, the image loses its resolution and become jaggy. I was wondering if there is any function I can apply to imported graphics so that they scale nicely. This would be important for both CDFs and presentations shown with a projector.
2. Is there a set of “best practices” in creating good looking Mathematica presentations? In Apple’s Keynote, for example, the font size for slide titles is often 64 to 72 points, and 40 points for bullets. These formatting considerations are taken care of. But I notice in Mathematica that we go from regular notebooks, where text cells are 12-point Times, to presentations by entering presentation mode where font sizes stay the same. Is it okay to stick with that or should I be creating presentation templates with 40-point text for slide bullets and much bigger text for slide titles and subtitles? I realize that it is easy to change font sizes, but that would mean maintaining two notebooks for each topic, one for class notes that would be distributed as CDFs and the other, with big fonts and big math, for presentations. That would be a hassle.
3. Do I have to worry about cross-platform compatibility of fonts in CDFs? When I create a PDF, the fonts I use are embedded, so I can use Didot, which is installed on most Macs but not Windows, and be sure that my Windows users will be able to see what I intended them to see. Craig answered this, and he says that Mathematica generates all of the fonts for CDFs, so it is not a problem. However, he referred to CDFs running in a browser. Can anyone confirm that the fonts are embedded in CDF files? I don't much like browser stuff and especially Flash, and it has been my experience that students find downloadable files more useful.
4. Whenever I create notes in PDF for my students, I use a consistent look. I’d like to do that with my CDFs and presentations, and I’m wondering whether there is an easy tutorial on creating and importing style sheets. This would be a big timesaver because any change to a style could then be reflected in all of my documents. Is there a Stylesheets-For-Dummies tutorial? Once again, being able to apply a stylesheet to many documents automatically is going to make for a good workflow.
5. Is there a menu item or keyboard shortcut that would allow me to collapse all parent cells of a particular type, for example, “Collapse all Sections,” or close all input cells, in those cases where I don’t want students to see or be able to modify the input? Apparently, yes, but my wish for future versions of Mathematica would be to have menu items for the purpose.
CDFs are cool. It was only last night that I came across Wolfram's web page on embedding them. One limitation, or more accurately, a missed opportunity, that I see in their use in education and research is the inability to export and import, although I can see why Wolfram needs to block that. [...] With CDFs as they are now, I can create a nifty grade report where students can look up their grades by choosing their student ID in a popup menu in a Manipulate, as long as I update the CDF with new grades and repost it every time a new assignment or test has been down; but if the CDF allowed importing, all I'd have to do is update the file of raw grades. Not a big difference, but all the same.
If you poke around the Option Inspector, you'll find an option for "EmbedExternalFonts". I believe this embeds non-Mathematica fonts assuming that the font's properties allow for embedding, and I also believe this is new functionality that wasn't available in previous versions.
