前在网上有一个CPictureEx类，用于加载GIF动画，不过该类是mfc封装类，对于不使用mfc的c++程序员来讲，不能使用。为了让该类能够让更多的人方便的使用，使其不再被局限于MFC，花时间改造了一下这个类，改造，该类可以应用于任何MFC、 WTL/ATL及其它INDOWS API编程。由于原来的CPictureEx是继承于CStatic类，改造后，在CPictureEx中直接封装了一个窗口句柄HWND。假设您在一个弹出式Dialog对话框中加载gif动画，您要做的就是在对话框中放一个控件，可以是BUTTON、STATIC等等。假设您加的这个控件的ID是IDC_FLASH，您的对话框窗口句柄是hDlg，则要使用CPictureEx，将非常简单。详情参见源代码。-ago on the Internet which is a CPictureEx category for loading GIF animation, But such is mfc Packaging category for the non-use of the c mfc speaking programmers, which can not be used. To allow such to allow more people to use, it will not be confined to the MFC. renovation of time spent on this category, transformation and can be applied to any such MFC, WTL/ATL and other INDOWS API programming. As the original CPictureEx inherited from CStatic category that after transformation, In CPictureEx directly Packaging a window handle HWND. Suppose you in a pop-up dialog box loaded Dialog gif animation You need to be done is up in a dialog box controls can be

原创，实现了Windows抓屏和保存。其实编写时主要目的是测试StretchBlt函数，此函数在许多机器上运行有BUG，可以用这个程序测试。-originality, the realization of the Windows Capturing the Screen and preservation. In fact, the main purpose of writing is to test StretchBlt function, this function in many machines running on a BUG, can use this test procedure.

其实颜色直方图简单来说，就是统计图像中具有某一特定颜色的象素点数目而形成的各颜色的直方图表示，不同的直方图代表不同图片的特征-color histogram simple fact, it is statistical image with a specific color of the pixel number of points which are in the color histogram, different pictures representing different histogram feature
