矢量图形有两个缺点，在实际应用中经常会造成麻烦。 首先，由于矢量图形是由显示图形的图形程序即时重新绘制的，因此同一个图形在两个不同的程序或两台不同的计算机上看起来可能会有差异。 这种问题最常发生在文本上，例如，当所需字体不可用时，渲染软件就会替换成另一种字体。字体替换通常可以让浏览者按照预期阅读文本，但生成的图像很少好看。有一些方法可以避免这些问题，例如在 PDF 文件中勾画或嵌入所有字体，但这可能需要特殊的软件和/或特殊的技术知识才能实现。相比之下，位图图像看起来总是一样的。

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
