推荐答案

您想要什么与他们在一起吗?
如果您是在对原始像素进行操作之后，那么位图和不安全的代码就可以解决(假设您不能使用本机C ++).但是它们会变得巨大，并且需要大量的RAM才能快速工作.

如果您想将它们扔到互联网上，则JPG/PNG/GIF会小很多，并且可以更快地进行传输.但是，它们有损，并且无法提供最佳的图像质量.

没有最佳"表演者:这完全取决于您想对他们做什么.

What do you want to do with them?
If you are after raw pixel manipulation, then bitmap and unsafe code is the way to go (assuming you can''t use native C++). But they can get huge and require substantial quantities of RAM to work fast.

If you want to throw them around the internet, then JPG / PNG / GIF are a lot smaller and can be transferred a lot more quickly. But, they are lossy, and don''t give the best picture quality.

There is no "best" performer: it''s all down to what you want to do with them.
