谁可以编码这个（不是我的原因是什么？只要有人看到这样的东西，好奇。

Who might code this (it's not me!) and for what reason?? Just curious if anyone has seen something like this.

推荐答案

它看起来像一个字体的渲染蒙版（字体中的每个字符（字体+大小+样式）都被渲染一次内存中，然后使用8bpp打印到输出表面），这表示您已启用字体反锯齿。

It looks like a rendered mask for a font (each character in a font (typeface+size+style) is rendered once in-memory, then blitted to the output surface) using 8bpp, which suggests you've got font anti-aliasing enabled.

我假设您的项目涉及到GUI ，您可能会看到GDI用于存储光栅化字体的共享内存区域。

I'm assuming your project involves a GUI, you might be looking at a shared-memory area that GDI uses for storing rasterized fonts.

如果没有，那么这可能只是来自以前进程或操作系统的剩余内存组件在应用程序使用之前未归零。

If not, then this might just be leftover memory from a previous process or OS component that wasn't zeroed before being used by your application.
