为什么透明图像在颤振中看起来质量较差？ [英] Why Transparent Images Look Poor Quality in Flutter?

问题描述

我有带阴影的png图像。没有不成比例的图像缩放问题，缩放比例取决于纵横比。

I have png images that have drop shadow. There is no unproportional images scaling problem, scaling are according to the aspect ratio.

当我使用 Image.asset（）用于将图像放置在手机屏幕上，它们的阴影看上去质量低而不柔和。

When I using Image.asset() for placing images on phone screen, they're and their shadows looks low quality and not soft.

原始图像看起来： http://prnt.sc/p93vo2

Android应用上的图片： https://prnt.sc/p93vz3

Image on Android App: https://prnt.sc/p93vz3

示例图片相同和700x400、96dpi。
您应该看到图像之间的质量差异。
还有一个奇怪的陈述。右侧和底部的阴影密度大于android应用中原始图像的阴影。

Example images are same and 700x400, 96dpi. You should see quality difference between images. There is also a strange stuation. The shadow density on right and bottom side is more than shadow of original image on android app.

我已经尝试过 FilterQuality.high 但没有更改，如何解决？

I've tried FilterQuality.high but no change, how to fix it?
