动画图像Objective-C
我正在使用一个动画块来迭代一组.png图像,使其看起来像是一个角色在屏幕上行走。但是,当我缩小图像时,图像的质量会模糊。目前,我正在测试19幅图像的动画,全部分辨率为371 x 379。但是,我需要它们在屏幕上显示得更小,所以我在我的应用程序中将它们缩放到64 x 65。当我这样做的时候,线条会有点扭曲,当我暂停游戏时,你会发现图像质量并没有达到应有的水平。下面是我用来遍历图像的代码。任何帮助都将不胜感激动画图像Objective-C,objective-c,graphics,uiimageview,core-animation,Objective C,Graphics,Uiimageview,Core Animation,我正在使用一个动画块来迭代一组.png图像,使其看起来像是一个角色在屏幕上行走。但是,当我缩小图像时,图像的质量会模糊。目前,我正在测试19幅图像的动画,全部分辨率为371 x 379。但是,我需要它们在屏幕上显示得更小,所以我在我的应用程序中将它们缩放到64 x 65。当我这样做的时候,线条会有点扭曲,当我暂停游戏时,你会发现图像质量并没有达到应有的水平。下面是我用来遍历图像的代码。任何帮助都将不胜感激 [UIImageView animaiteWithDuration: 3.0

因此,如果有人能告诉我,我是否需要做一些额外的事情来防止图像失真,或者可能是图像本身,我真的可以在阅读Apple API中的所有内容并查看互联网上的每个论坛时使用一些技巧。你的问题应该与代码无关。您正在将图像调整为不同的纵横比。您应该非常小心调整图像大小,因为图像会自然模糊
您最好的选择是创建精确(清晰)的图像,专门针对您将使用它们的大小而设计。您的问题应该与代码无关。您正在将图像调整为不同的纵横比。您应该非常小心调整图像大小,因为图像会自然模糊
