SwfDotNet的使用，多幅图片生成SWF

标签：

突然要做一个将多幅图片拼成一个swf的工作，而且还是用没有用过的C#，还好语法基本和java类似，网上找了一圈，找到一个SwfDotNet的插件，网址如下：

http://www.codeproject.com/KB/graphics/jpeg2swf.aspx?fid=369197&df=90&mpp=10&noise=3&prof=True&sort=Position&view=Quick&fr=21

页面上有示例代码，但仅针对一副图片，看不出来swf的效果，以下代码大部分使用示例代码，关键代码我会注释说明。

Image img = Image.FromFile(jpegFileName);
int posX = 0;
int posY = 0;
int imgWidth = img.Width;
int imgHeight = img.Height;

//Create a new Swf instance
Swf swf = new Swf();
//Set size in inch unit (1 pixel = 20 inches)
swf.Size = new Rect(0, 0, (posX + imgWidth) * 20, (posY + imgHeight) * 20);
swf.Version = 7;  //Version 7 (for compression, must be > 5)
swf.Header.Signature = "CWS";  //Set the signature to compress the swf
swf.Header.Fps = 1;//每秒多少帧，这个很重要，加入多幅图片后，依靠这个控制速度 
//Set the background color tag as white
swf.Tags.Add(new SetBackgroundColorTag(255, 255, 255));

//Set the jpeg tag
ushort jpegId = swf.GetNewDefineId();
//Load the jped directly from an image
//In fact, this line will load the jpeg data in the file as 
//a library element only (not to display the jpeg)
swf.Tags.Add(DefineBitsJpeg2Tag.FromImage(jpegId, img));

//Now we will define the picture‘s shape tag
//to define all the transformations on the picture 
//(as rotation, color effects, etc..) 
DefineShapeTag shapeTag = new DefineShapeTag();
shapeTag.CharacterId = swf.GetNewDefineId();
shapeTag.Rect = new Rect(posX * 20 - 1, posY * 20 - 1, 
     (posX + imgWidth) * 20 - 1, (posY + imgHeight) * 20 - 1);
FillStyleCollection fillStyles = new FillStyleCollection();
fillStyles.Add(new BitmapFill(FillStyleType.ClippedBitmapFill, 
      ushort.MaxValue, new Matrix(0, 0, 20, 20)));
fillStyles.Add(new BitmapFill(FillStyleType.ClippedBitmapFill, 
               jpegId, new Matrix(posX * 20 - 1, posY * 20 - 1, 
               (20.0 * imgWidth) / img.Width, 
               (20.0 * imgHeight) / img.Height)));
LineStyleCollection lineStyles = new LineStyleCollection();
ShapeRecordCollection shapes = new ShapeRecordCollection();
shapes.Add(new StyleChangeRecord(posX * 20 - 1, posY * 20 - 1, 2));
shapes.Add(new StraightEdgeRecord(imgWidth * 20, 0));
shapes.Add(new StraightEdgeRecord(0, imgHeight * 20));
shapes.Add(new StraightEdgeRecord(-imgWidth * 20, 0));
shapes.Add(new StraightEdgeRecord(0, -imgHeight * 20));
shapes.Add(new EndShapeRecord());
shapeTag.ShapeWithStyle = 
   new ShapeWithStyle(fillStyles, lineStyles, shapes);
swf.Tags.Add(shapeTag);

//Place the picture to the screen with depth=1
swf.Tags.Add(new PlaceObject2Tag(shapeTag.CharacterId, 1, 0, 0));

//Add a single frame
swf.Tags.Add(new ShowFrameTag());//这个也很重要，按照前面设置的fps参数，每秒1帧，重复多设置几帧，这个图片就能持续显示几秒
swf.Tags.Add(new ShowFrameTag()); 
swf.Tags.Add(new ShowFrameTag());//我这里重复了3次，就可以显示3秒了
swf.Tags.Add(new RemoveObject2Tag(1));//这个也很重要，前面的图片插入到了哪个层，就把哪个层移除掉，类似于图片叠加置前置后的那种 
//以下为添加第二幅图片 
image = System.Drawing.Image.FromFile("2.jpg"); 
imgid = swf.GetNewDefineId(); 
shapeTag = new DefineShapeTag(); 
shapeTag.CharacterId = swf.GetNewDefineId(); 
shapeTag.Rect = new SwfDotNet.IO.Tags.Types.Rect(posX * 20 - 1, posY * 20 - 1,(posX + imageWidth) * 20 - 1, (posY + imageWidth) * 20 - 1);
fillStyles = new FillStyleCollection(); 
fillStyles.Add(new SwfDotNet.IO.Tags.Types.BitmapFill(FillStyleType.ClippedBitmapFill, ushort.MaxValue, new SwfDotNet.IO.Tags.Types.Matrix(0, 0, 20, 20))); 
fillStyles.Add(new BitmapFill(FillStyleType.ClippedBitmapFill, imgid, new SwfDotNet.IO.Tags.Types.Matrix(posX * 20 - 1, posY * 20 - 1,(20.0 * imageWidth) / image.Width,(20.0 * imageHeight) / image.Height))); 
lineStyles = new LineStyleCollection(); shapes = new ShapeRecordCollection(); 
shapes.Add(new StyleChangeRecord(posX * 20 - 1, posY * 20 - 1, 2)); 
shapes.Add(new StraightEdgeRecord(imageWidth * 20, 0)); 
shapes.Add(new StraightEdgeRecord(0, imageHeight * 20)); 
shapes.Add(new StraightEdgeRecord(-imageWidth * 20, 0)); 
shapes.Add(new StraightEdgeRecord(0, -imageHeight * 20)); 
shapes.Add(new EndShapeRecord()); 
shapeTag.ShapeWithStyle = new ShapeWithStyle(fillStyles, lineStyles, shapes); 
swf.Tags.Add(shapeTag); //Place the picture to the screen with depth=1，将图片在屏幕中的的深度设置为1 
swf.Tags.Add(new PlaceObject2Tag(shapeTag.CharacterId, 1, 0, 0)); 
//Add a single frame 
swf.Tags.Add(new ShowFrameTag());//这个和第一副图片的帧参数一个意思
swf.Tags.Add(new EndTag());
//Write the swf to a file
SwfWriter writer = new SwfWriter(outputSwfFileName);
writer.Write(swf);
writer.Close();

img.Dispose();
好了，总算把这个问题解决了，记录下，百度空间竟然关闭了，记录到这里好了！
