每天解决一个问题25天2问 ：使用word实现图片大小转换

lkl0305

之前给大家分享了excel实现正弦波数据，今天给大家分享一个word的小用法。

一、问题提出：
在学习OLED时，想显示个图片，但是原始图片的大小一般不符合要求，这就需要图片大小的裁剪、缩放等调整。但是电脑上又没有PS之类的专业图片编辑工具，怎么办？

二、解决办法：
估计每个人电脑上都会装word，使用word就可以很方便的实现转换。
我们以社区的logo为例吧。

把图片插入到word！但是显示的单位是厘米。

而我们想要像素为单位，也可以的，在选项，高级中，勾选如图的设置。

重新查看，发现显示像素了。

调整成列128即可
另存为html格式


然后放到画图中另存为bmp文件


最后生成的图片提取字模


生成的字模为：

1. <font size="3">const uint8_t logoBmp[] = {
   
2. 0x00,0x00,0x00,0x00,0x00,0x00,0x80,0xC0,0xC0,0xC0,0xC0,0xC0,0xC0,0xC0,0xC0,0xC0,
