[英]How to create .swf file from multi .JPG images using swflib library in Visual C++?
我正在編寫一個 C++ 代碼來從多 JPG 圖片創建一個動畫 SWF 文件。
現在,我有像“image_0”到“image_100”這樣的圖片。 我找到了一個swflib庫。 我認為它會有所幫助。 到目前為止,我可以使用這個庫的方法創建.SWF文件,.SWF文件的大小是.JPG格式的圖片的總和。
所以,我想我差不多完成了。 但是,SWF 不播放。 我瘋了。 下面是我修改的代碼:
`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();
}`
你能告訴我我的代碼有什么問題嗎? 提前致謝。
我找到了一種使用 C++ 和一個swflib庫從一組圖像創建 .SWF 文件的方法。您可以從lib 文件網站下載它。其中有一個名為:CreateSWFMovie_Bitmap()的方法,這里是我的代碼修改的
void 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值也不能一樣 id不能重復
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);//必須define才能動 可以不update
swfMovie.ShowFrame();
}
