printbutton : button for printing a matplotlib plot figure

class tesfdmtools.utils.widgets.printbutton.PrintPlot(canvas, window, text=None, orientation='portrait', fontsize=12, font='Bitstream Vera Sans Mono', parent=None)

Opens a Gtk.PrintOperation widget for sending the given plot and text to the printer.

Needs the debian package gir1.2-poppler-0.18 (or higher version) to be installed.

Args:

• canvas = the canvas containing the plot

• window = not used

Kwargs:

• text = text to be with after the plot (only operational for ‘portrait’ mode)

• orientation = ‘portrait’ or ‘landscape’

• fontsize = fontsize (pts) to be used for the text

• font = fonttype to be used

• parent = not used

tesfdmtools.utils.widgets.printbutton.printbutton(figure, parent=None, orientation='portrait')

Insert a printbutton in the matplotlib navigation toolbar. Pressing the button opens a printdialog for printing the current figure plot.

Args:

• figure = the matplotlib figure object

Kwargs:

• orientation = orientation of the plot. landscape or portrait

Example of use

Below is an example of use from a piece of python code using pyplot:

import numpy

import matplotlib
matplotlib.use('GTK3Agg')

import matplotlib.pyplot as plt              # import plt

from tesfdmtools.utils.widgets.printbutton import printbutton        # import printbutton

fig = plt.figure()                   # initialize matpplotlib figure
ax1 = fig.add_subplot(111)           # define axis

printbutton(fig)                     # insert printbutton in toolbar

x=numpy.arange(100)/100.0*numpy.pi*2.0       # define function
y=numpy.sin(x)

ax1.plot(x,y)                                # plot function
ax1.set_title('test printbutton')
ax1.set_xlabel('X')
ax1.set_ylabel('Y')

fig.caption=['This shows the use of the printbutton',\
             'printbutton is inserted in the toolbar']  # some text which goes with the plot

plt.show()                           # show plot, with printbutton in toolbar
plt.close('all')

The pyplot window will show as follows, with the printbutton inserted in the toolbar

The preview of the plot, which is sent to the printer is shown below
