ggb files

A ggb (GeoGebra) file is used to save a GeoGebra construction including gui settings, user-defined-tools, and image files. A ggb file is a zip-archive with the following contents:

• geogebra.xml is an XML file describing the main construction
• geogebra_macro.xml (optional) is an XML file describing user-defined-tools
• geogebra_thumbnail.png (optional) is a PNG with maximum dimensions 200 pixels by 200 pixels of the Graphics View at the time of saving
• image files (optional) are saved in subfolders

ggt files

A ggt (GeoGebra Tools) file is used to save one or several user-defined-tools of GeoGebra together with all necessary image and icon files. A ggt file is a zip-archive with the following contents:

• geogebra_macro.xml is an XML file describing one or several user-defined-tools
• image files (optional) are saved in subfolders

geogebra_macro.xml

The geogebra_macro.xml file describes user-defined-tools and has the following structure.

<?xml version="1.0" encoding="utf-8"?>      

 <geogebra format="3.2">

  <macro>

    <macroInput>
        ...                  <-- the <macroInput> tag
    </macroInput>

    <macroOutput>
        ...                  <-- the <macroOutput> tag
    </macroOutput>

    <construction>              
       ...                   <-- the <construction> tag
    </construction>

 </macro>
