背景需求：
幼儿操作时明显感觉到塑封纸反光，黄色很容易和背景融合，看不清楚。

所以我想让图形生成时，直接有一个黑色边线，便于区分图形
AI生成
1、把以下的代码复制到AI内【教学类-50-01】20240407“数一数”图片样式01：纯色图形与边框不相交，纯色图形和其他纯色图形不相交-CSDN博客
2、补充需求：几何图形轮廓线是黑色的
3、只要加上一个边框颜色，就完成了

打印展示：
感悟：
1.PDF上三种填充和黑色边框线都很鲜艳，
2.但是打印后，几何图案的黑色边框看上去更像灰色（线条很细）
3.这一套题目是图案之间不重叠，所以黑色边框还是有很大作用的。
这篇关于【教学类-50-07】20240502“数一数”图片样式07：数一数（几何图案——图形有黑色外框线）的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
