Parameters

ImageID
GdPicture image identifier. The multiframe gif image.

Return Value

Number of frames in the multiframe gif image. Returns 0 if the image is not a multiframe gif image.
Remarks
This method works with both editable multiframe gif images and ones opened as read-only.
Example
Creating a multiframe Gif image based on image files. 
using (GdPictureImaging gdpictureImaging = new GdPictureImaging())

{

    // Create a new editable multiframe Gif image based on an image file and append frames from files.

    int imageID = gdpictureImaging.GifCreateMultiFrameFromFile("frame1.bmp");

    gdpictureImaging.GifAppendFrameFromFile(imageID, "frame2.bmp");

    gdpictureImaging.GifAppendFrameFromFile(imageID, "frame3.bmp");

    gdpictureImaging.GifAppendFrameFromFile(imageID, "frame4.bmp");

    gdpictureImaging.GifAppendFrameFromFile(imageID, "frame5.bmp");

 

    // Set the number of times the animation should be played, 0 = infinite.

    gdpictureImaging.GifSetLoopCount(imageID, 0);

 

    // Set the "frame time" for each and every frame to 1s and the frame disposal to leave the image in place to beentirely or partially overdrawn by the next image.

    int frameCount = gdpictureImaging.GifGetFrameCount(imageID);

    for (int frameNo = 1; frameNo <= frameCount; frameNo++)

    {

        gdpictureImaging.GifSetFrameTime(imageID, frameNo, 100);

        gdpictureImaging.GifSetFrameDisposal(imageID, frameNo, 1);

    }

 

    gdpictureImaging.GifSaveMultiFrameToFile(imageID, "image.gif");

    gdpictureImaging.ReleaseGdPictureImage(imageID);

}
