| ====== Python 使用reportlab 创建PDF格式日历 ====== | ====== Python 使用reportlab 创建PDF格式日历 ====== | ||
| + | 使用到的模块有： | ||
| - | ===== Python 源代码 ===== | + | * calendar (python self contained) |
| + | * reportlab | ||
| + | ===== 功能修改 ===== | ||
| + | 做了下面的一些修改。 | ||
| + | |||
| + | ==== 字体 ==== | ||
| + | |||
| + | 在源代码里面增加了字体部分： | ||
| <code python> | <code python> | ||
| - | #!/usr/bin/env python | + | canvas.setFont("Times-Roman", 20) |
| - | """Create a PDF calendar. | + | </code> |
| - | This script requires Python and Reportlab | + | ==== 增加日历的星期名称 ==== |
| - | ( http://reportlab.org/rl_toolkit.html ). Tested only with Python 2.4 and | + | |
| - | Reportlab 1.2. | + | |
| - | See bottom of file for an example of usage. No command-line interface has been | + | <code python> |
| - | added, but it would be trivial to do so. Furthermore, this script is pretty | + | weekheader = ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat' ]; |
| - | hacky, and could use some refactoring, but it works for what it's intended | + | </code> |
| - | to do. | + | |
| - | Created by Bill Mill on 11/16/05, this script is in the public domain. There | + | 日历表格中行数增加一行，表格的线也都补齐了。 |
| - | are no express warranties, so if you mess stuff up with this script, it's not | + | |
| - | my fault. | + | 生成的日历PDF文件为： {{ :python-files:python-generate-printable-calendar.pdf |}} |
