如何使用 Visual C++ 中的 swflib 库从多个 .JPG 图像创建 .swf 文件？

Question

我正在编写一个 c++ 代码来从多个 JPG 图片创建动画 SWF 文件。

现在，我有 "image_0" 到 "image_100" 这样的图片。我找到了一个 swflib 库。我认为这会有所帮助。至此，我可以使用这个库的方法创建.SWF文件，.SWF文件的大小是.JPG格式图片的总和。

所以，我想我差不多完成了。但是，SWF 不播放。我疯了。下面是我修改的代码：

`void CSWFLIBTestProjectDlg::CreateSWFMovie_Bitmap()
{
    // Set movie params
    SIZE_F movieSize = {100, 100};
    int frameRate = 14;
    POINT_F pt;

    // Create empty .SWF file
    CSWFMovie swfMovie;

    swfMovie.OpenSWFFile(_T("SWF Sample Movies/Sample2.swf"), movieSize, frameRate);

    SWF_RGB bgColor = {255, 255, 255};
    swfMovie.SetBackgroundColor(bgColor);

    // Define bitmap object
    CSWFBitmap bitmap(2, (UCHAR*)"gif_0.jpg");//bm128
    swfMovie.DefineObject(&bitmap, -1, true);

    // Define custom shape
    RECT_F shapeRect = {0, 0, 1000, 1000};
    CSWFShape shape(1, shapeRect, 1);
    SWF_RGBA lineColor = {0, 0, 0, 255};
    shape.AddLineStyle(0, lineColor);
    RECT_F bitmapRect = {0, 0, 1246, 622};                              // size of the bitmap
    RECT_F clipRect = {0, 0, 100, 100};                                 // where to fill
    shape.AddBitmapFillStyle(bitmap.m_ID, SWF_FILLSTYLETYPE_BITMAP_0, bitmapRect, clipRect);
    pt.x = 0;
    pt.y = 0;
    shape.ChangeStyle(1, 1, 0, &pt);
    shape.AddLineSegment(100, 0);
    shape.AddLineSegment(0, 100);
    shape.AddLineSegment(-100, 0);
    shape.AddLineSegment(0, -100);


    swfMovie.DefineObject(&shape, shape.m_Depth, true);

    swfMovie.ShowFrame();
    /****************************************
    *   move
    ****************************************/
    float i;
    for (i=0; i<10; i++)
    {
        shape.Translate(i, 0);
        swfMovie.UpdateObject(&shape, shape.m_Depth, NULL, -1);
        swfMovie.ShowFrame();
        //if (i>200)
        //{ 
        //  swfMovie.RemoveObject(shape.m_Depth);

        //}

    }


/****************************************
 *  add jpg
 ****************************************/

    swfMovie.RemoveObject(shape.m_Depth);

    for (int i=1;i<=100;i++)
    {
        char filename[100]; 
        sprintf(filename,"gif_%d%s",i,".jpg");

        CSWFBitmap bitmap2(3, (UCHAR*)filename);//gif_0
        swfMovie.DefineObject(&bitmap2, -1, true);//

        // Define custom shape
        RECT_F shapeRect2 = {0, 0, 1000, 1000};
        CSWFShape shape2(1, shapeRect2, 1);
        SWF_RGBA lineColor2 = {0, 0, 0, 255};
        shape2.AddLineStyle(0, lineColor2);
        RECT_F bitmapRect2 = {0, 0, 1246, 622};                             // size of the bitmap
        RECT_F clipRect2 = {0, 0, 100, 100};                                    // where to fill
        shape2.AddBitmapFillStyle(bitmap2.m_ID, SWF_FILLSTYLETYPE_BITMAP_0, bitmapRect2, clipRect2);
        pt.x = 0;
        pt.y = 0;
        shape2.ChangeStyle(1, 1, 0, &pt);
        shape2.AddLineSegment(100, 0);
        shape2.AddLineSegment(0, 100);
        shape2.AddLineSegment(-100, 0);
        shape2.AddLineSegment(0, -100);

        swfMovie.UpdateObject(&shape2, shape2.m_Depth, NULL, -1);
        //swfMovie.DefineObject(&shape2, shape2.m_Depth, true);

        swfMovie.ShowFrame(); 
        //swfMovie.RemoveObject(shape2.m_Depth);


    }








    // Close .SWF file
    swfMovie.CloseSWFFile();
}`

你能告诉我我的代码有什么问题吗？提前致谢。

我找到了一种使用 C++ 从一组图像创建 .SWF 文件的方法，swflib library.you 可以从 [=11= 下载它] .其中有一个名为 :CreateSWFMovie_Bitmap() 的方法，这里是我修改的代码

无效CSWFLIBTestProjectDlg::CreateSWFMovie_Bitmap() {

SIZE_F movieSize = {4000, 4000};
int frameRate = 40;
POINT_F pt;


CSWFMovie swfMovie;
swfMovie.OpenSWFFile(_T("SWF Sample Movies/Sample2.swf"), movieSize, frameRate);
SWF_RGB bgColor = {255, 255, 255};
swfMovie.SetBackgroundColor(bgColor);


CSWFBitmap bitmap(2, (UCHAR*)"bm128.jpg");
swfMovie.DefineObject(&bitmap, -1, false);


RECT_F shapeRect = {0, 0, 1000, 1000};//shape大小
CSWFShape shape(1, shapeRect, 1);
SWF_RGBA lineColor = {0, 0, 0, 255};
shape.AddLineStyle(3, lineColor);
RECT_F bitmapRect = {0, 0, 128, 128};                               // size of the bitmap
RECT_F clipRect = {0, 0, 100, 100};                                 // where to fill
shape.AddBitmapFillStyle(bitmap.m_ID, SWF_FILLSTYLETYPE_BITMAP_0, bitmapRect, clipRect);
pt.x = 0;
pt.y = 0;
shape.ChangeStyle(1, 1, 0, &pt);
shape.AddLineSegment(100, 0);
shape.AddLineSegment(0, 100);
shape.AddLineSegment(-100, 0);
shape.AddLineSegment(0, -100);
swfMovie.DefineObject(&shape, shape.m_Depth, true);
swfMovie.ShowFrame();



for (int i=0; i<100; i++)
{
    char filename[50]=""; 
    sprintf(filename,"gif_%d%s",i,".jpg");
    CSWFBitmap bitmap2(300+i, (UCHAR*)filename);
    swfMovie.DefineObject(&bitmap2, -1, false);//false
    CSWFShape shape2(7+i,shapeRect,2+i);//depth值也不能一样 id不能重复
    shape2.AddLineStyle(3, lineColor);
    RECT_F bitmapRect2 = {0, 0, 128, 128};                              
    RECT_F clipRect2 = {0, 0, 100, 100};                                    
    shape2.AddBitmapFillStyle(bitmap2.m_ID, SWF_FILLSTYLETYPE_BITMAP_0, bitmapRect2, clipRect2);

    pt.x = 0;
    pt.y = 0;
    shape2.ChangeStyle(1, 1, 0, &pt);
    shape2.AddLineSegment(1000, 0);
    shape2.AddLineSegment(0, 1000);
    shape2.AddLineSegment(-1000, 0);
    shape2.AddLineSegment(0, -1000);
    shape2.Translate(80, 0);
    swfMovie.DefineObject(&shape2, shape2.m_Depth, true);//必须define才能动 可以不update

    swfMovie.ShowFrame();


}
