GeoGebra XML File Format 2.1

Changes to previous version:

• New subtag <labelOffset> of <element>

• New tags <gui> and subtag <show>, <font>, <splitDivider>
• <euclidianView>: attributes scale, xZero, yZero in <coordSystem> have now double values (former int)

construction

A construction has three string attributes: title, author and date.

<construction title="Construction Title" author="Me" date="1.12.2003">

     <element type="point" label="P"> ...  </element>    

     <command name="Intersect"> ...    </command>

     <expression label="T" exp="A + 1/2 (B-A)"/>

</construction>

element

An element has two attributes: type and label. The following types are valid: point, vector, line, segment, conic, numeric, angle, function.

<element type="line" label="a">

     <show object="true" label="true"/>

     <objColor r="0" g="0" b="255"/>

     <lineStyle thickness="2" type="0"/>

<eqnStyle style="implicit"/>

     <coords x="6.0" y="7.8" z="1.0"/>

</element>

Tags for types point, vector, line, segment, conic, function

<show object="true" label="true"/>

<objColor r="0" g="0" b="255"/>

<labelOffset x="10" y="5"/>

Tags for types vector, line, segment, conic, function

<lineStyle thickness="2" type="0"/>

where type is an integer representing one of the following dashing styles:

0	LINE_TYPE_FULL
10	LINE_TYPE_DASHED_SHORT
15	LINE_TYPE_DASHED_LONG
20	LINE_TYPE_DOTTED
30	LINE_TYPE_DASHED_DOTTED

Tags for types line, conic

<eqnStyle style=" ... " parameter=" ... " />

For an element of type line attribute style may have values explicit, implicit or parametric. For parametric the second attribute parameter specifies the parameter's name.

For an element of type conic attribute style may have values implicit or specific.

Tags for types point, vector, line, segment

<coords x="6.0" y="7.8" z="1.0"/>

where style has value cartesian or polar
