![ConTeXt:添加两行页面边框](https://linux22.com/image/470253/ConTeXt%EF%BC%9A%E6%B7%BB%E5%8A%A0%E4%B8%A4%E8%A1%8C%E9%A1%B5%E9%9D%A2%E8%BE%B9%E6%A1%86.png)
最近我尝试在 ConTeXt 中为文档添加一个简单的双页边框(使用 mtx-context 版本:2023.09.26 18:19)。例如,更正式的封面或文档可能会使用类似的东西。
如果使用 LaTeX,我会使用eso-pic
或只是添加一个tikzpicture
矩形。现在使用 ConTeXt。如果使用单线,我会使用\framed
如下图所示的https://wiki.contextgarden.net/Framed。但是现在给定一个偏移量和两条要绘制的线。我开始在 MetaPost 中绘制矩形,\startuseMPgraphic
使用unitsquare
并移动它们。
在 ConTeXt 中还有其他(可能更简单)的选项可以做到这一点吗?
我的最小例子:

\setuppapersize[A4][A4]
\setuplayout[topspace=24mm,
backspace=24mm,
header=0pt,
footer=0pt,
height=middle,
width=middle]
\setuppagenumbering[location=]
\setupbodyfont [12pt]
\startuseMPgraphic{pagebackground}
StartPage ;
path outerPath, innerPath;
numeric offset, margin, w, h;
offset := 10mm;
margin := 1mm;
w := OverlayWidth;
h := OverlayHeight;
outerPath := unitsquare xysized (w - 2*offset, h - 2*offset);
outerPath := outerPath shifted (offset, offset);
innerPath := unitsquare xysized (w - 2*offset - 2*margin, h - 2*offset - 2*margin);
innerPath := innerPath shifted (offset + margin, offset + margin);
draw outerPath withpen pencircle scaled 2pt withcolor red;
draw innerPath withpen pencircle scaled 1pt withcolor red;
StopPage ;

您可以将背景应用到文本区域并使用OverlayBox
具有文本块大小的背景,并enlarged
设置边框的偏移量。
\startuseMPgraphic{pageborder}
draw OverlayBox enlarged 10mm withpen pencircle scaled 1pt withcolor "red";
draw OverlayBox enlarged 11mm withpen pencircle scaled 2pt withcolor "red";
\stopuseMPgraphic
