在头文件里面添加:
Image* image; GUID Guid ; UINT frameCount; UINT framePos;
ULONG_PTR gdiplusToken;
afx_msg void OnTimer(UINT_PTR nIDEvent);
void LoadGif();
需要依赖头文件:
#include <Gdiplusheaders.h> #include <Gdiplus.h> using namespace Gdiplus;
界面类的构造函数里面添加:
//启动gdi 要不然 Image::FromFile 会失败 GdiplusStartupInput gdiplusStartupInput; GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL); image = NULL; frameCount = 0; framePos = 0;
添加定时器消息处理:
BEGIN_MESSAGE_MAP(CMFCApplication1Dlg, CDialogEx) ON_WM_SYSCOMMAND() ON_WM_PAINT() ON_WM_QUERYDRAGICON() ON_BN_CLICKED(IDC_BUTTON1, &CMFCApplication1Dlg::OnBnClickedButton1) ON_WM_TIMER() ON_BN_CLICKED(IDC_BUTTON2, &CMFCApplication1Dlg::OnBnClickedButton2) END_MESSAGE_MAP()
加载GIF文件:
void CMFCApplication1Dlg::LoadGif() { WCHAR strModule[MAX_PATH * 2] = { 0 }; GetModuleFileNameW(NULL, strModule, MAX_PATH * 2); ::PathRemoveFileSpecW(strModule); wsprintfW(strModule + wcslen(strModule), L"\\%s.gif", L"sVcodec"); image = Image::FromFile(strModule); //获得有多少个维度,对于gif就一个维度 UINT count = image->GetFrameDimensionsCount(); GUID *pDimensionIDs = (GUID*)new GUID[count]; image->GetFrameDimensionsList(pDimensionIDs, count); WCHAR strGuid[39]; StringFromGUID2(pDimensionIDs[0], strGuid, 39); frameCount = image->GetFrameCount(&pDimensionIDs[0]); //delete[] pDimensionIDs; //获得各帧之间的时间间隔 //先获得有多少个时间间隔,PropertyTagFrameDelay是GDI+中预定义的一个GIG属性ID值,表示标签帧数据的延迟时间 UINT FrameDelayNums = image->GetPropertyItemSize(PropertyTagFrameDelay); PropertyItem* lpPropertyItem = new PropertyItem[FrameDelayNums]; image->GetPropertyItem(PropertyTagFrameDelay, FrameDelayNums, lpPropertyItem); Guid = FrameDimensionTime; image->SelectActiveFrame(&Guid, framePos); }
定时器处理:
void CMFCApplication1Dlg::OnTimer(UINT_PTR nIDEvent) { if (image) { CWnd* pic = GetDlgItem(IDC_STATIC_PIC); Graphics gh(pic->GetDC()->m_hDC); CRect rect; GetDlgItem(IDC_STATIC_PIC)->GetClientRect(&rect); gh.DrawImage(image, 0, 0, rect.Width(), rect.Height()); //gh.DrawImage(image, 0, 0, image->GetWidth(), image->GetHeight()); //设置当前需要显示的帧数 image->SelectActiveFrame(&Guid, framePos); framePos++; if (framePos == frameCount) { framePos = 0; } } CDialogEx::OnTimer(nIDEvent); }
启动定时器:
SetTimer(0, 400, NULL); LoadGif();
需要依赖gdi 库:
gdiplus.lib
