How can I produce a printable PDF file (US letter sized) such that each page represents a month and is partitioned such that each day of the month gets a box of equal size? What if I want to skip weekends and just display weekdays?
What Python modules would I use to accomplish the following?:
You could do it with 3 packages. 'Reportlab' for producing the pdf, 'calendar' for getting the month as lists of lists, and python binding for 'Ghostscript' to transform the pdf produced into a png.
You would start by getting the data from the calendar package, using Reportlab to produce a page of US letter size. The table can be manipulated to have a grid, have each cell a box of the same size and alter the text font, size, and alignment.
You could leave it at that if you just want a pdf, or you can convert this pdf into a image using Ghostscript python bindings. Or if you like you can just run 'Ghostscript' using system('gs ...'). Also Ghostscript must be installed for the python 'Ghostscript' package to work.
If you want to filter out all weekends then you can use good old fashioned list manipulation on the calendar data for that.
Here is a example of how you could produce the pdf. I'm not going to do a whole year just a single month, and I'm not going to bother filtering out the zeros.
from reportlab.lib.units import inch from reportlab.lib import colors from reportlab.lib.pagesizes import letter from reportlab.platypus import SimpleDocTemplate, Table, TableStyle from reportlab.graphics.shapes import Drawing import calendar doc = SimpleDocTemplate('calendar.pdf', pagesize=letter) cal = [['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']] cal.extend(calendar.monthcalendar(2011,9)) table = Table(cal, 7*[inch], len(cal) * [inch]) table.setStyle(TableStyle([ ('FONT', (0, 0), (-1, -1), 'Helvetica'), ('FONT', (0, 0), (-1, 0), 'Helvetica-Bold'), ('FONTSIZE', (0, 0), (-1, -1), 8), ('INNERGRID', (0, 0), (-1, -1), 0.25, colors.black), ('BOX', (0, 0), (-1, -1), 0.25, colors.green), ('ALIGN', (0, 0), (-1, -1), 'CENTER'), ('VALIGN', (0, 0), (-1, -1), 'MIDDLE'), ])) #create the pdf with this doc.build([table])
If you want another page add PageBreak() followed by the next calendar to the list passed to doc.build(). PageBreak is part of reportlab.platypus.
And to convert the pdf to png
import ghostscript args = ['gs', #it seems not to matter what is put in 1st position '-dSAFER', '-dBATCH', '-dNOPAUSE', '-sDEVICE=png16m', '-r100', '-sOutputFile=calendar.png', 'calendar.pdf'] ghostscript.Ghostscript(*args)
Both reportlab and ghostscript packages are available through the use of pip. I created the above in a 'virtualenv' environment.

calendar is part of the standard python library.
