Adjust newpage() calls

Note

The Macro to Python converter is available from Metview version 5.22.0

We can use newpage() to add a new page to a Postscript or PDF output. In Macro we can call it multiple times for a given graphical output. However, in Python it behaves differently and can only be called as an argument of plot(). The converter is not able ensure this behaviour, instead a warning is placed to the top of the generated Python script and the adjustment has to be made manually.

The following example demonstrates how this conversion can be done:

Macro code

# define PDF output setoutput(pdf_output(output_name: "my_output")) # create display window with one page dw = plot_superpage(pages: [plot_page(view: geoview())]) # plot first page plot(dw, fs_1, visdef_1) # plot second page newpage() plot(dw, fs_2, visdef_2)

Adjusted Python code

# define PDF output mv.setoutput(mv.pdf_output(output_name="my_output")) # create display window with one page dw = mv.plot_superpage(pages=[mv.plot_page(view=mv.geoview())]) # collect all the plot arguments into a list plt_data = [] plt_data.extend([dw, fs_1, visdef_1]) plt_data.append(mv.newpage()) plt_data.extend([dw, fs_2, visdef_2]) # call plot with all the arguments mv.plot(plt_data)
