• Create a Magics python skeleton that displays a global map using the plot command
  • Create and use an output object to set-up  name and format of your output
  • Improve mcoast to taylor the coastlines.
  • Add a mtext object to add some texts.

 

Step by step

In order to be able to create and use Magics objects, the Magics python package has to be imported.

from Magics.macro import *

Any Magics plots will be triggered using the plot command, the simplest plot example is :

plot(mcoast())

The result will be a geographical map, using the default projection, and the default attributes of coastlines.

Magics will instantiate the default driver.

 

 

from Magics.macro import *

plot(mcoast())

 

Create a postscript file called ps.ps, mcoast() create a default coastlines object.

 

 


Setting the output

The object output allows the selection of the output format, and the setting of the output filename .

Have a look at the  PNG output documentation  to see which parameters are available to set-up a PNG output.

To create a PNG output Magics, you have to create an output object and to insert at the first position in the plot command

 

from Magics.macro import *

#settings of the png output 
output = output(
			output_formats = ['png'],
  			output_name = "magics",
    		output_name_first_page_number = "off"
    )

#The plot commad will create a png output called magics.png
plot(output, mcoast())
