将大型打印作业作为带有对齐标记的PDF进行布局。
lps的Python项目详细描述
获取图像、打印高度或宽度（以mm为单位）和页面大小，然后 使用对齐标记在多个页面上拆分图像并生成 PDF格式
它用于打印从Openscad导出为svg的投影
对于图像，它支持枕头支持的任何东西，以及SVG 多亏了Cairosvg。
pdf生成由reportlab完成。
$ lps -h
usage: lps [-h] (--width WIDTH | --height HEIGHT) [--page_size PAGE_SIZE]
[--overlap OVERLAP] [--margins MARGINS] [--outfile OUTFILE]
[--svg_start_scale SVG_START_SCALE]
image_file
positional arguments:
image_file Image to parse
optional arguments:
-h, --help show this help message and exit
--width WIDTH Width of image in millimeters
--height HEIGHT Height of image in millimeters
--page_size PAGE_SIZE
Page size, e.g. a3, a4
--overlap OVERLAP Print overlap in mm
--margins MARGINS Print margins in mm
--outfile OUTFILE Filename to save pdf to
--svg_start_scale SVG_START_SCALE
When using SVG, this is the largest scale factor to
attempt to generate an image
$ lps --width 970 --page_size a3 --overlap 20 wrap.svg
