Solved the problem of movieclip thumbnails.

The movieclip thumbnail problem has just been solved. below is my:

 

The red section below is the key to modifying and adding thumbnails.Code.

Modify pages. mxml

Modify and add:

Private function createpages (Event: Event): void
{
VaR MC: movieclip = application. application. libmc;

For (var I: Int = 1; I <= mc. totalframes; I ++)
{
Box = new page ();
MC. gotoandstop (I );
VaR bitimage: bitmapdata = new bitmapdata (MC. Width, MC. Height );

VaR M: matrix = new matrix ();
Bitimage. Draw (MC, M );

// The key is to convert bitmapdata into a bitmap object before binding it to the image control.
VaR mymap: bitmap = new Bitmap (bitimage );

Box. mapdata = mymap;
Box. pagenumber = I;
Addchild (box );
Box. addeventlistener (mouseevent. Click, dispatchpage );
}
// Return to the first frame
MC. gotoandstop (1 );
}

 

Modify page. mxml

Added:

[Bindable] private var mymap: bitmap;

Public Function set mapdata (value: Bitmap): void {
Mymap = value;
}

<Mx: Image id = "clipimage" Source = "{mymap}" width = "100%" Height = "100%" horizontalalign = "center" verticalalign = "Middle"/>

 

In my movieclip implementation, I mainly refer to the online materials. I would like to share them with other users and thank you for your reference.ArticleThe work of the authors.
