如何用ImageMagick将8×8黑白SVG无失真缩放为80×80 PNG？

我有一个由8×8黑白“像素”组成的SVG图形，SVG代码如下：

<?xml version="1.0"?>
<svg xmlns="http://www.w3.org/2000/svg" width="8" height="8" viewBox="0 0 8 8">
<path fill="#fff" d="M0,0H8V8H0"/>
<path fill="#000" d="M0,0H7V1H6V0H5V3H8V2H7V5H6V5H6V4H8V6H7V8H8V7H1V8H2V5H3V6H4V7H5V4H2V1H3V2H4V3H1V4H0"
fill-rule="evenodd"/>
</svg>

我使用以下ImageMagick命令尝试缩放：

convert a3x2.svg -scale 80x80 a3x2.png

得到的结果与输入完全不符；使用-resize 80x80也无效，会出现模糊且像素值错误的问题。我需要的是将每个原始像素放大为10×10的黑白PNG，无平滑或抖动效果。

补充说明 #

使用Inkscape命令可以实现需求：

inkscape -w 80 -h 80 a3x2.svg -o a3x2.png

该命令能得到正确的转换结果（每个原始像素被无失真放大为10×10的黑白块），但我更倾向使用ImageMagick完成这个操作。

我的ImageMagick版本信息：

执行convert -verbose a3x2.svg txt:的输出结果如下：
