(NOTE: this functionality is available starting from .NET 2.0 version of the library)

Introduction

 

Saving a snapshot of the frame is very easy with new Aspose.Flash frame rendering feature (available  from version 1.6.2),  it’s implemented using fully managed .NET code and brings you an ability to save any desired frame of the movie to an image.

 

Remarks

 

Frame content is rendered statically, without any internal Action Script executions, our renderer only renders display list content defined for the given frame.

 

List of the supported elements includes:

1) shapes with solid, gradient and bitmap fill or clipping shapes

2) static and dynamic text, with embedded or system fonts

3) morph shapes support

4) buttons support

5) sprites

 

Bitmap filters and blending modes are not supported by the moment for DefineButton and PlaceObject3 tags as well as DefineFont4 tag introduced with swf 10.

 

RenderFrame method

 

The RenderFrame method creates a flash container, loads a movie into it  and demonstrates usage of the rendering feature. 

 

[C#]

 

//Create a flash container/flash file

FlashContainer flash = new FlashContainer();

//Reads the movie from disk

flash.ReadFromFile(“movie.swf”);

 

//Render the first frame of the movie

Image image = flash.Render();

 

//Write snapshot on disk

image.SaveToFile("snapshot.png",System.Drawing.Imaging.ImageFormat.Png);

 

 

[VB.NET]

 

'Create a flash container or flash file

Dim flash As New FlashContainer()

'Reads the movie from disk

flash.ReadFromFile("movie.swf")

Render the first frame of the movie

Dim image As Image = flash.Render()

 

'Write snapshot on disk

image.SaveToFile("snapshot.png", System.Drawing.Imaging.ImageFormat.Png)
