I want to print a monthly calendar on A3 (or 11x17", tabloid) paper, with spiral bindings in the middle of the (cut) sheet. The top half is a nice photo and the bottom is one month, with custom events that I control.
I also know about this Inkscape plugin but it only generates a full year on one page, not at all what I need. And there are various PDF, PowerPoint or ODT templates lying around, but none of those make my life any easier.
I want to programmatically generate the calendar. I have over 30 events I need to fill in and I don't want to do each by hand.
Said tool would also be free software based. Output would be PDF or SVG or some accessible format.
