[FileType plugins Using WIC CODEC]

The WPF wrapper only supports saving the built-in codecs.

Humm, if you're right, the only way for me to save image in my custom format is to export C function directly in C#.

Thanks for the answers!!

[FileType plugins Using WIC CODEC]

hi there!

I just develop a new file format and the associated WIC codec.

Now I'm trying to develop the paint.NET File Type plugins to open and SAVE in my format into PDN.

I succeed to open an image in PDN with the function onLoad :

protected override Document OnLoad(Stream input)
{
try
{
	BitmapSource bitmapSourcetest = null;
	MemoryStream imageStream = null;
	BitmapCreateOptions createOptions = BitmapCreateOptions.PreservePixelFormat | BitmapCreateOptions.IgnoreColorProfile;
	BitmapDecoder myDecoder = BitmapDecoder.Create(input, createOptions, BitmapCacheOption.None);

	if (myDecoder.Frames[0] != null)
	{
		bitmapSourcetest = myDecoder .Frames[0];
	}

	//Save the image in a Memory stream
	System.Windows.Media.Imaging.BmpBitmapEncoder bmpEncoder = new System.Windows.Media.Imaging.BmpBitmapEncoder();

	bmpEncoder.Frames.Add(System.Windows.Media.Imaging.BitmapFrame.Create(bitmapSourcetest));
	imageStream = new MemoryStream();
	bmpEncoder.Save(imageStream);
	Bitmap b = new System.Drawing.Bitmap(imageStream);

	myContainerFormat = myDecoder.CodecInfo.ContainerFormat;

	return Document.FromImage(;
}
catch
{
	MessageBox.Show("Problem Importing File");
	Bitmap b = new Bitmap(500, 500);
	return Document.FromImage(;
}
}

BitmapDecoder.Create creates the decoder by calling the wic dll. and myContainerFormat gives me the correct GUID container format.

Now it's getting more complicated with the method onSave.

I try this code :

protected override void OnSave(Document input, Stream output, SaveConfigToken token, Surface scratchSurface, ProgressEventHandler callback)
{
myEncoder = BitmapEncoder.Create(myContainerFormat);

myEncoder.Save(output);
 /*using (RenderArgs ra = new RenderArgs(scratchSurface))
{
	input.Render(ra, true);
	ra.Bitmap.Save(output, ImageFormat.Bmp);
 }*/
}

I can't create the encoder based on my wic dll it always return an UnknownBitmapEncoder.

Anyone as a clue on using the WIC with PDN ????

Thanks for answers.
