如何在Windows Phone 7中更正颜色条带？ [英] How can I correct color banding in windows phone 7?

问题描述

我的Windows Phone 7应用程序有非常漂亮的背景图像，但他们正在被16位彩色设备上的彩色条带破坏。有没有办法我可以纠正这个？我已经尝试保存在photoshop中的几种不同的模式无效。

My windows phone 7 app has very nice background images but they are being destroyed by color banding on a 16bit color device. Is there a way I can correct this? I have tried saving in several different modes in photoshop to no avail.

推荐答案

您需要使用抖动。 Floyd-Steinberg 是一种简单且运行速度快的算法。

You need to use dithering. Floyd-Steinberg is a good algorithm that is simple and runs fast.

你不需要像另一个答案所建议的那样去每像素8位，你可以直接去每个像素16位。你需要知道在开始之前如何拆分为R / G / B。

You don't need to go to 8 bits per pixel as suggested by another answer, you can go directly to 16 bits per pixel. You need to know how it is split into R/G/B before you begin.

这里有一些例子，首先是原来的24位：

Here are some examples, first up is the original 24-bit:

接下来是一个16位没有抖动：

Next is a 16-bit without dithering:

最后16位使用Floyd-Steinberg抖动。

Finally 16-bit with Floyd-Steinberg dithering.

PS我做这个与Paint Shop Pro，我不知道Photoshop有什么类似的。你也可以在代码中做。

P.S. I did this with Paint Shop Pro, I don't know if Photoshop has anything similar. You can do it in code as well.
