WIC和GDI +之间有什么关系？ [英] What's the relationship between WIC and GDI+?

问题描述

我对Windows成像组件（WIC）和GDI +之间的关系很模糊。过去我做了一些工作，例如，WIC产生了视觉上优秀的GIF编码，但我很惊讶我没有看到更多的人将它用于图像处理与GDI +。我知道它没有GDI +的绘制操作，但对于编码/解码来说它似乎更好。那么为什么我们不能看到迁移？WIC和GDI +之间的关系（或更确切的说是WIC）是一个可扩展的图像编解码器框架，它允许实现该框架的应用程序通过提供的编解码器获得对新图像格式的支持。 GDI +是Windows的核心组件，它支持诸如线条，字体，渐变等的绘制操作。

虽然GDI +支持多种常见图像格式，但WIC编解码器可以提供任何图像格式。

I'm fuzzy on the relationship between Windows Imaging Component (WIC) and GDI+. I've done some work in the past that showed that, for example, WIC produces visually superior GIF encodings, but I'm surprised I don't see more people using it for image processing vs. GDI+. I know it doesn't have GDI+'s draw operations, but for encoding/decoding it seems superior. So why don't we see a migration?

解决方案

The relationship (or rather the difference between) WIC and GDI+ is that WIC is an extensible imaging codec framework which allows applications implementing the framework to receive support for new image formats via provided codecs. GDI+ is a core component of Windows which supports draw operations such as lines, fonts, gradients, etc.

While GDI+ has native support for several common image formats, WIC codecs can be provided for any image format.
