Re: st: Video from multiple graph exports
I see. I had misinterpreted your earlier response to suggest that
you had done something more fancy, but I suspect for some users these
represent useful ideas to get started. I could imagine extending
this to examples such as integrating automatic PDF generation into an
ado file, passing options to epstopdf via Stata, and/or engaging in
batch processing of files from within Stata.
For my own curiosity, is the "start" command standard in the Windows
equivalent of a shell? (I'm so used to working with Unix-based OSs,
I'm not even sure if "shell" is the right word here.) Does it simply
launch the program associated with the file extension of the listed
file -- in this case some pre-specified PDF reader?
Thanks,
Mike

Martin:
Since epstopdf is available for the same three platforms as Stata
(i.e., Mac, Unix, Windows), perhaps a few examples showing how
you "talk to it from inside Stata" would be of general interest.
Indeed, without stepping on the feet of the Stata Journal
editors, I think this would be a good topic for a Stata Tip in an
upcoming issue of the SJ.

Well, epstopdf is free as well and I know how to talk to it from

Any Mac can "print to PDF" and there are a number of options for
getting a PC to print to PDF. One reliable free version is
"PDFCreator"

"Export the Stata graphs as PDF format. (A feature only available

In Windows, -gr export- as .eps and use !epstopdf from your MikTeX
distribution. Not much more effort than on the MAC...

Dan:
I have done something like this for several presentations --
although I
typically prefer to use a remote to step through the "movie
frames"
rather than automate the transitions. That way I can stop and
comment on
certain slides (the audience sees it as "freezing" the
animation), or go
back to a specific slide to answer questions.
The caveat, given the details you have provided in your
message: my
process requires a Macintosh. Specifically, it requires use of
Keynote,
Apple's presentation software available only for Mac OS X.
Briefly, in three steps (though I am happy to provide details if
requested):
1. Export the Stata graphs as PDF format. (A feature only
available in
the Mac version, I believe.)
2. Place PDFs of graphs into individual slides in Keynote.
3. Add automatic timed transitions and effects as needed. You
can set
transition times on a per-slide basis, as you inquired.
This whole process is very easy with Keynote, as it provides fine
controls for aligning the graphs and professional transitions
between
slides. Plus, since everything is done with PDF, you don't
get those
"jaggies" (i.e. pixelation) that often afflict graphics in
PowerPoint.
Additionally, with Keynote you can export your presentation to
QuickTime
(.mov) or Flash (.swf) formats as a self- running, cross-
platform file if
desired.
I suspect one could use LaTeX-based presentation tools (beamer?
powerdot?
prosper?) to accomplish the same thing, albeit with (much)
more effort.
Hope this helps,
Mike

Hi Folks,
I'm considering making a movie using multiple Stata graphs,
exported.
E.g., for t=0,1,...n, graphing the data at each t, and then
using a
slide-show program to stack the graphs in time order, creating a
"movie" illustrating how the data changes over time.
My questions:
1. Has anyone does this before, and if so, do you have
recommendations for the most flexible slide-show program?
Specifically, I'm wondering if there is a program that will
allow for
variable intervals between slides (e.g., t=0, 1.5, 2, 2.2,....)
2. Is there a way to overlay a Stata graph on top of a .jpg
file?
I've been doing this manually, using -spmap- to plot my
location-oriented data, exporting graphs as .emf/.wmf,
ungrouping the
result in PowerPoint and aligning the .jpg overlay.
3. Am I trying to use Stata to do something it's not suited
for? I
know JMP can play movies from data, but I don't think the
movies can
be exported, and, well, I'm partial to Stata.
Thanks in advance,
-Dan
