wxGUICartographicComposer also called wx.psmap is a wxGUI extension which allows the user to create
interactively hardcopy map outputs. This tool generates ps.map configuration file and then runs ps.map to
create PostScript output. There are two modes - Draftmode for map composing and Previewmode (requires
Python Imaging Library) to see how the result will look like. In draft mode map features (like legend or
scalebar) are represented by a colored rectangle with a label.
Possible output files:
• ps.map instructions file
• PostScript/EPS file
• PDF (using ps2pdf)
Cartographic Composer enables to load in saved instructions file. Loading instruction files created by
Cartographic Composer is more robust, as opposed to loading files created manually.
Currently supported ps.map instructions:
• paper
• maploc
• scale
• border
• raster
• colortable
• vpoints
• vlines
• vareas
• vlegend
• text
• scalebar
• mapinfo
• point
• line
• rectangle
• labels
CARTOGRAPHICCOMPOSERTOOLBARGenerateinstructionsfile
Generates and saves text file with mapping instructions.
Loadinstructionsfile
Load text file with mapping instructions.
Pagesetup
Specify paper size, margins and orientation.
Pointer
Select object on the paper by clicking, drag the cursor while pressing the left mouse button to move
it or resize object (currently only map frame) by clicking on a small black box in its bottom right
corner. Double click to show object properties dialog
Pan
Drag the pan cursor while pressing the left mouse button to move your view.
Zoomin
Interactive zooming with the mouse in both draft and preview mode. Drawing a box or just a left click
with the mouse and zoom-in cursor causes the display to zoom in so that the area defined by the box
fills the display.
Zoomout
Interactive zooming with the mouse in both draft and preview mode. Drawing a box or just a left click
with the mouse and zoom-out cursor causes the display to zoom out so that the area displayed shrinks
to fill the area defined by the box.
Zoomtopage
Zoom to display the entire page
Mapframe
Click and drag to place map frame. If map frame is already drawn, open a dialog to set its
properties.
Rastermap
Shows a dialog to add or change the raster map.
Vectormap
Shows a dialog to add or change current vector maps and their properties:
Dataselection
Select data to draw:
Featuretype
Select which data type to draw. In case of point data, points or centroids can be drawn, in case of
line data, lines or boundaries.
Layerselection

Linestyle
Available for line data. Select line style (solid, dashed, ...) and the look of the ends of the line
(butt, round, ...)
Pattern
Available for areas. Choose pattern file and set the width of the pattern.
Size
Available for point data. Choose size (number of times larger than the size in the icon file) as a
single value or take the size from a map table column.
Rotation
Available for point data. Rotate symbols counterclockwise with the given value or with the value from
a map table column
Width
Available for line data. Set line width in points or take the value from a map table column.
Addoverlays
Add overlays: vector labels, grid (not yet implemented)
Addlabels
