我一直在使用C ++为“使命召唤”(第一次c ++体验,对不起n00b)制作一名教练,最后今天结束。 有一个小问题; 我项目最终版本中的图片(PNG)不会显示。
可以在此处查看图片:http://imgur.com/6mWtETS,0ajBwE9,JlMVUYR,k8AIbAn#0
(前两个是调试教练时得到的。
我认为这与我如何使用GDI +加载图片有关,但我不确切知道是什么,因为培训师不会产生任何错误。
如果有人想知道,我使用的是Visual Studio 2013。
答案 0 :(得分:0)
您正在尝试从文件(cfr。Image GDI+ object constructor)加载图像,这意味着图像必须位于应用程序驻留在Windows平台上的同一目录中。
