-OpenJUMP can warp vector layers. Warping modifies all the features in a selected layer according to some specified parametres, like vectors. please see also the good documentation in VIVID SOLUTIONs [http://www.vividsolutions.com/jump/bin/JUMP%20User%20Guide.pdf Jump Workbench User's Guide], page 41 to 43.

 * '''Warping''' - It opens a warping dialog containing several buttons to create and delete warping vectors. Warping vectors are created in a new layer and the deformation of the source layer can be processed in one time, or incrementaly, after each vector addition. The triangulation used to interpolate the deformation can also be displayed.

 Geometrical analysis of features. Results are usually saved to a new layer.
-* '''Buffer...''' - This function creates a buffer for every selected geometry if any geometry is selected or for all features of the selected layer if there is no feature selected.
+* '''Buffer...''' - This function creates a buffer around selected features if one or more geometries are selected or around all features if there is no feature selected.
 *:''Union option'' - Buffer tool provides an option to union the result.
 *:''Keep attributes'' - Buffer copies feature attributes by default. If selected features have different schemas, only attributes from the selected layer schema are copied. Attribute copy can be turned off.
-*:''Number of segments'' - Buffer also supports to set the number of segments per circle quarter. May be useful to create lighter geometries as buffer tends to create geometries which have much more points than source geometries.
+*:''Advanced options'' - A second panel offers the following advanced options : end cap style, join style and single sided buffers
 For more information about the buffer plugin, see page [[Buffer PlugIn]]
 * '''Buffer (Multiple Rings)...''' -  Unlike previous buffer tool, this one works only on selected features and there is no option to set end cap style or number of segments. There are buffer options to set up to 10 concentric buffers. User can set the distance and a label for each buffer individually. Unlike normal buffers, the new features do not overlap the inner areas. When multiple features are selected, overlapping Ring Buffers are unioned.

-* '''Beanshell Attribute Calculator <span style="color:red">[OpenJUMP 1.6]</span>''' - Users can compute a new attribute from a beanshell script. Moreover, attribute can be made dynamic by checking the Dynamic checkbox. It means that the value is not stored in memory but evaluated on demand. You can download a screencast from [http://geo.michaelm.free.fr/OpenJUMP/resources/video/ here].
+* '''[[Beanshell Attribute Calculator]] <span style="color:red">[OpenJUMP 1.6]</span>''' - Users can compute a new attribute from a beanshell script. This is a very powerfull plugin, but it needs some knowledge about how to code a beanshell snippet. See the dedicated page. Note that calculated attribute can be made dynamic by checking the Dynamic checkbox. It means that the value is not stored in memory but evaluated on demand. You can download a screencast from [http://geo.michaelm.free.fr/OpenJUMP/resources/video/ here].
 * '''Join TXT table''' - Users can import datas  from a .TXT or .TEXT file into a layer. New datas must have a ''Tab delimitated'' format (Note, the Pirol CSV plugin has advanced table reading functions, e.g. to import points from CSV files).

 * '''Triangulation <span style="color:red">[OpenJUMP 1.6]</span>''' - Triangulate sites contained in a layer (if the layer contains linestrings or polygons, each vertex is considered as a site). Optionally, a second layer containing constraint lines (or break lines) can be defined. This layer must contains linestrings or polygons. If the constraint layer contains polygons, you can exclude triangles located out of the polygons from the result.
 * '''Voronoï diagram <span style="color:red">[OpenJUMP 1.6]</span>''' - Create a Voronoï diagram from a layer containing sites. Cells located on the border of the diagram are extended out of the layer bounding box, to a distance equal to the layer boundingbox size. Optionally, one can transfer attributes from the input site to the result cells.
