Hope this helps, Mike On Dec 3, 2008, at 7:48 PM, Dan Weitzenfeld wrote:

I think I'm barking up the wrong tree. I found, in a previous statalist discussion, "At the moment Stata does not allow a level of transparency in the graphics engine." It seems that transparency support would be necessary for overlaying a graph on top of an image. Indeed, when I try exporting .pngs with regions having "zero" fill, the resulting file is still opaque.

Sergiy,Basically I'm trying to overlay a graph on top of an image - theimagecan be .jpg, .png, etc. To give you a concrete example, one type of data I work with is eye-tracking data, so I would like to - withinStata - generate a graph in which the image/stimuli is thebackground.The shp -> GIS package is an interesting idea, but it feels likeoverkill because (with the help of -spmap-) Stata will doeverything Ineed except for putting a graph on top of an image. I'll definitely look into it, though. Has anyone written a program that converts -spmap- files (e.g. Basemap files) to .shp? -DanOn Wed, Dec 3, 2008 at 4:05 PM, Sergiy Radyakin<serjradyakin@gmail.com> wrote:Hi! I've done videos like that. Once you have all your frames in .png files, select all of them, drag and drop to the Windows MovieMaker,there check that they are in the proper sequence, and place themintothe timeline. You can adjust the delay interval individually foreachfile or for the whole sequence. You can add a soundtrack right away. Then save as a video file (wmv). Example available.Alternatively, many viewers support command line activated slideshowmode, for Windows platform, check free IrfanView, which is an excellent Viewer/Converter. I don't think you will have a lot of control though, e.g. setting individual delays for each file. http://www.irfanview.com/ http://gd.tuwien.ac.at/graphics/irfantut/commopti.html As for Q2, Stata does not support JPG files for any purpose and you should not either. JPG is a format for digital photography, for noise-rich analog-to-digital conversion (via scanner of digital camera) from the real world to the world of computers. For imagesgenerated inside your computer, use one of the lossless formats,likepng. Why don't you export your data to shp format from Stata andplotin a GIS package?

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 willallow forvariable 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 mylocation-oriented data, exporting graphs as .emf/.wmf,ungrouping theresult in PowerPoint and aligning the .jpg overlay.3. Am I trying to use Stata to do something it's not suitedfor? Iknow JMP can play movies from data, but I don't think the moviescanbe exported, and, well, I'm partial to Stata.
