我正在尝试用 tikz 制作折纸模板。我制作了一个 latex 文档，四边边距均为 0.5 厘米。这是我的 tikz 代码：
\documentclass[landscape,a4paper]{article}
\usepackage[top=0.5cm, bottom=0.5cm, left=0.5cm, right=0.5cm]{geometry}
\usepackage{float}
\usepackage{graphics}
\usepackage{graphicx}

\usetikzlibrary{patterns}
\usetikzlibrary{shapes,arrows}
\usetikzlibrary{decorations.pathreplacing}

生成以下页面：
如果你仔细观察，你会发现整个图像似乎都向下移动了。我在 tikz 代码的开头有一个注释掉的矩形，它应该在可打印区域周围放置一个边框。
如果我注释掉最后 4 行（曲线），那么 tikz 图片就在正确的位置。
我并不太担心精确的比例，我真正想要的是它在页面上尽可能大 - 例如，图像的顶部和底部应该接触页面的边缘。
答案1
顶部和底部使用零长度。

看起来 tikz 有一些尾随空格。但是，这是我的代码的输出：
