Exporting an Animated or Static GIF.

eugbug shared this question 1 year ago

I'm trying to export a GIF of a graph. Neither the app nor the online browser version of Geogebra allow me to do this. In the app I have tried using "Export Image" but it does nothing. I also tried selecting "File", but it does nothing either (even if I right click and draw a selection box around a region of the graph). I can't find any option to export in Geogebra online. Also is there an option yet to export an animated GIF?

Which app are you using?

I'm using GeoGebra Classic. Where do I check the version number?

Menu -> Help & Feedback -> About/Licence


Anyway, I was lucky guessing your app, and the instructions for Classic 6 are below ;)

When I highlight a section of graph and select "Export Image", the menu disappears but there is no preview or option to select "download". I can however display the menu again in order to pick "download as", but there's no option to save as a GIF (not a problem because I can convert anyway in any image editing software application).

Do I have to select the region of the graph to save or can I save the whole viewport? If I'm going to have to make an animate GIF manually from a series of stills, they wont be aligned unless I choose the exact same selection for each still.

You can make (hidden) points called

Export_1
Export_2

to define the export rectangle

If it's GeoGebra Classic 6


1. draw a selection rectangle (right click and drag) containing the area that you want to export as a pic

2. select the menu icon on top right, then select Export image

3. a preview of the image is shown. Select Download

4. a dialog window opens, where you can browse your hard disk, select the target folder and assign a name to the file.

If you want to use ExportImage command (see the wiki for more options)

1. resize the Graphics View, because it'll be exported globally.

2.Say you want to use this syntax:

ExportImage("filename", "image.png", "scalecm", 2, "dpi", 600)


This command saves a file called "image.png" of the current view at 600 dpi at a scale 1 unit = 2 cm

Replace "image.png" with the name of the file you want to obtain

Replace 2 with the desired unit in cm


Replace 600 with the desired dpi.


For animated gifs, use the syntaxes listed in the wiki page, e.g.

ExportImage("filename", "image.gif", "type", "gif", "slider", a, "loop", true, "time", 200, "width", 400)
in which all the terms in double quotes are not modifiable, except "image.gif" that is the filename that you want to save.

Please see the wiki for further info, or post a file and explain what portion of it you want to export

Oh yes, I now have a dim distant memory of using that command on a slider a few months ago to generate all the stills!
