NAME¶

wxGUI.PsMap

DESCRIPTION¶

Note: wxGUI Cartographic Composer is currently under development. wxGUI Cartographic Composer 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 - Draft mode for map composing and Preview mode (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: Cartographic Composer enables to load in saved instructions file. It works better with files created by wx.psmap (more tested). Currently supported ps.map instructions:

CARTOGRAPHIC COMPOSER TOOLBAR¶

Generate instructions file

 

Generates and saves text file with mapping instructions.

Load instructions file

 

Load text file with mapping instructions.

Page setup

 

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.

Zoom in

 

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.

Zoom out

 

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.

Zoom to page

 

Zoom to display the entire page

Map frame

 

Click and drag to place map frame. If map frame is already drawn, open a dialog to set its properties.

Raster map

 

Shows a dialog to add or change the raster map.

Vector map

 

Shows a dialog to add or change current vector maps and their properties:

Data selection

 

Select data to draw:

Feature type

 

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.

Layer selection

 

Select layer and limit data by a SQL query or chose only certain categories.

Mask

 

Whether to use mask or not.

Colors

 

Color settings:

Outline

 

Select outline color and width in points. In case of lines, outline means highlighting.

Fill

 

Select fill color, one color for all vector elements or color from rgb column.

Size and style

Sets size, style, symbols, pattern; depends on data type:

Symbology

Line style

 

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.

Add map elements

 

Add map elements: legend, scalebar, map info, text

Add legend

 

Add raster or vector legend or edit their properties.

Add map info

 

Add information about region, grid and scale or edit map info properties.

Add scalebar

 

Add scalebar or edit its properties.

Add text

 

Add text label.

Remove selected element

 

Select an object and remove it. Pressing Delete key does the same.

Show preview

 

Generates output and switches to Preview mode to see the result. Be patient, it can take a while.

Generate hardcopy map output in PS

 

Generates hardcopy map output in PostScript/EPS file.

Generate hardcopy map output in PDF

 

Generates hardcopy map output in PDF using ps2pdf.
