Question

我一直在用Slick2D制作游戏，最近我开始不得不使用控制台进行调试，我注意到我遇到了这些错误：

我完全不知道（经过大量研究）可能导致这种情况的原因。请问可以解释一下吗？

编辑：以下是第一个错误不喜欢的行：splash = new Image("res/img/splash.png"); 以下是第二个错误不喜欢的行：sandMap = new Image("res/img/map/sandmap.png");

编辑2： Sandmap.png Splash.png

Answer 1

如果你仍然遇到这个问题，我可能会有一个解决方案。我使用paint.net并遇到了同样的问题。从paint.net保存图像后，选择保存目标后会弹出保存配置窗口。对我来说，我不得不将Bit-Depth从8位更改为32位。自动检测有时会起作用，但只有当它自动检测到它为32位时。我没有测试24位，它也可以工作。希望这会有所帮助。

Answer 2

org.newdawn.slick.opengl.PNGImageData无法读取数据

此图片的格式不受支持

错误消息说明错了。您的图片已损坏，或不受支持，或未正确保存。你用的是什么样的图像？

Answer 3

@Anubian是正确的，你的PNG必须是腐败的。尝试重新制作它或使用其他软件来创建它。查看Slick2D抛出异常here的位置。我试图使用Wolfgang Fellger的PNG Analyzer，我甚至无法打开你的形象。
