Convert Images to SWF Format Using C#

Introduction:

In this article we will see how to convert our JPEG images to .swf format. For this we are using a third party's DLL which will convert our images to a .swf movie. For viewing the movies you can download the swf player.

Background:

Actually the DLL to convert images to swf I found using a Google search. In this article I'm using DLL files as given below to do our work.

log4net

SwfDotNet

SharpZipLib

Follow the steps given below to do our work.

Step 1:

Create a Windows Form application in C#. Add the reference to the DLLs that I have put in the bin folder of the attached source as well a "using" for this namespace in our using statements like:

using log4net;

using SwfDotNet.IO;

using SwfDotNet.IO.Tags;

using SwfDotNet.IO.Tags.Types;

Step 2:

Design the normal form for taking input filename and output path for our work with OpenFile Dialog and SaveFile Dialog.

Step 3:

In the click of the create button write the following code to convert the input file to .swf format and store it to the specified location.

try

            {

                if (File.Exists(inputfilename) == false)

                {

                    MessageBox.Show("Can not open Image file" + inputfilename);

                    return;

                }

                //First load the picture as System.Drawing.Image

                Image img = Image.FromFile(inputfilename);

                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

                //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  

                swf.Tags.Add(DefineBitsJpeg2Tag.FromImage(jpegId, img));
