<h2 id="注意">注意!</h2>
<p>本工具仅适用于将预处理好的图片转化为 gcode 代码,不适用于未经处理的原图,因为这会导致一些预期之外的问题!</p>
<h2 id="使用方法">使用方法:</h2>
<ol>
<li>配置运行库,本项目依靠 Pillow 库识别图片中的深色像素,在运行软件之前请确保你已经安装好这个库:</li>
</ol>
<pre><code>pip install pillow
</code></pre>
<ol start="2">
<li>
<p>修改代码开头部分的数值参数。对于使用 0.5 mm 墨水笔绘图的场景,建议毫米每点的值设为 0.25</p>
</li>
<li>
<p>调整图片分辨率,根据所需绘制总大小手动计算图片分辨率,计算公式为:调整后分辨率 = 实际绘图大小 (mm) × 毫米每点</p>
</li>
<li>
<p>将图片文件处理成黑白位图,处理算法可以根据需要选择,一般建议选择扩散仿色</p>
</li>
<li>
<p>保存图片副本为 <code>input.bmp</code></p>
</li>
<li>
<p>运行程序得到 <code>output.gcode</code></p>
</li>
</ol>
<p>得到生成好的代码以后,就可以丢到 CNC 软件中运行了~</p>
