- 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
|
taylor - Add a mtext object to add some texts.
|
|
|
First step
In order to be able to create and use Magics objects, the Magics python package has to be imported.
...
Magics will instantiate the default driver, a Postscript driver...

#The default plot command will create a ps called ps.ps
plot(mcoast()) |
|
Create a postscript file called ps.ps, mcoast() create a default coastlines object. | Column |

Setting the output
...
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

output = output(

output_name = "magics",
output_name_first_page_number = "off"
)
#The plot commadcommand will create a pngPNG output called magics.png
plot(output, mcoast()) |
...
The object mcoast allows the parametrisation parameterisation of the coastlines.
Have a look at the Coastlines documentation to see which parameters are available.
To configure the look of your coastlines you have to create a mcoast object with the parameters you want.
The mcoast object has to be inserted in the plot command.

Magics allows the user to add of or several lines of text. The position of the text is by default above the plot, but some parameters aloow allow it to be moved around.
Have a look at the Text Plotting Documentation
A basic html HTML formatting can be used for colour, style, and font size.
The mtext object has to be inserted in the plot command to see the text on the result.
