您无法在控制台应用程序中加载图像,需要创建Windows应用程序并使用各种位图功能显示图像.您可以先在项目资源中添加一个简单的位图,然后使用 ^ ].
You cannot load images in console apps, you need to create a Windows app and use the various Bitmap functions to display images. You could start by adding a simple bitmap to the resources of your project and use LoadImage()
[^].
我通常从控制台应用程序加载图像.执行诸如去偏斜和色彩还原之类的操作.
在控制台中显示1位图像也是一项琐碎的任务.
不久前,我放弃了LoadImage-发现增加的GDI +支持的格式值得过渡.
我时不时地忘记初始化GDI +,并且应用程序在启动时崩溃.否则,以下功能可以满足我的需求.
I commonly load images from console apps. Performing operations such as deskewing and colour reduction.
It''s also a trivial task to display 1 bit images in the console..
I gave-up on LoadImage a looong time ago - finding that the increased number of formats supported by GDI+ was worth the transition.
Every now and again I forget to initialize GDI+, and the app crashes upon startup. Otherwise, the following function performs adequetly for my needs.
// BMP, GIF, JPEG, PNG, TIFF, Exif, WMF, and EMF
HBITMAP mLoadImg(WCHAR *szFilename)
{
HBITMAP result=NULL;
Gdiplus::Bitmap* bitmap = new Gdiplus::Bitmap(szFilename,false);
bitmap->GetHBITMAP(NULL, &result);
delete bitmap;
return result;
}
使用此功能之前,必须调用以下初始化代码:
Before you use this function you must call the following init-code:
static Gdiplus::GdiplusStartupInput gdiplusStartupInput;
static ULONG_PTR gdiplusToken;
GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL);
之后,您必须关闭GDI +
Afterwards, you have to shut-down GDI+
Gdiplus::GdiplusShutdown(gdiplusToken);
您需要包含gdiplus.h头文件并链接gdiplus库
You''ll need to include the gdiplus.h header file and link the gdiplus library
