在Java应用程序端控制图像质量

我发布了一个问题，询问如何处理java应用程序中的模糊图片。我发现我的视窗缩放造成了模糊。现在我有一个更大的问题。我希望通过应用程序控制图像和应用程序的质量，如果可能的话，不必更改任何windows设置

不是将缩放比例改回100%，而是另一个windows建议，即更改java.exe和/或javaw.exe的兼容性设置，以覆盖高DPI设置，由系统执行缩放。它是有效的，因为画面更清晰，但文字却失去了清晰

我发现应用程序的最佳质量是不覆盖高DPI，而只是将缩放设置为100%。文字清晰，图片也清晰

我正在试图找出是否有一种方法可以保持这种质量，而不必让用户更改任何windows设置以使应用程序看起来良好。我想知道代码中是否有实现这一点的方法

下面是一个示例程序，我的缩放比例为125%。图片模糊，但文字良好。

下面是一个DPI被系统覆盖的示例，缩放比例仍为125%，注意文本失去了清晰性，但图片更好

最后，缩放为100%，不再覆盖DPI。这是最好的文字和图片质量

如果有人需要，下面是示例代码
