這有個數字雨的代碼,看能幫助你不!
⑶ 請教:怎麼樣能把C語言代碼運行後的流星雨效果圖保存下來,保存為GIF。
搞定。 我用的C++Builder XE2編譯器。 增中代碼: #include <vcl.h> #include <GIFimg.hpp> TGIFImage *image; 在wmain函數後部分: image = new TGIFImage(); srand((int) GetCurrentTime()); // 初始化隨機數發生器 image->Width = Screen->Width; image->Height = Screen->Height; while (GetMessage(&msg, NULL, 0, 0)) { TranslateMessage(&msg); DispatchMessage(&msg); } ShowCursor(TRUE); // 顯示滑鼠游標 image->SaveToFile("流星雨.gif"); delete image; 在WndProc函數處理WM_TIMER消息後面增加: BitBlt(hdc, 0, 0, cxScreen, cyScreen, hdcMem, 0, 0, SRCCOPY); { Graphics::TBitmap *bmp = new Graphics::TBitmap; bmp->Width=Screen->Width; bmp->Height=Screen->Height; BitBlt(HDC(bmp->Canvas->Handle), 0, 0, cxScreen, cyScreen, hdcMem, 0, 0, SRCCOPY); image->Add(bmp); delete bmp; } ReleaseDC(hwnd, hdc); 編譯後成功。 保存的GIF文件很大,最好用Ulead GIF Animator優化一下。 需要編譯後的文件QQ我:1848447992
記得採納啊
