BitmapImage to byte[]

Postby fangeles » Thu Feb 07, 2019 12:01 am

Is there a solution for converting BitmapImage to byte array? (or any equivalent)
Image will be from Image.Source.
The purpose is to send the image to WCF Service

I've got the code for converting byte[] to BitmapImage

Code: Select all

        public static BitmapImage byteArrayToImage(byte[] byteArrayIn)
        {
            BitmapImage bmi = new BitmapImage();
            MemoryStream ms = new MemoryStream(byteArrayIn);
            bmi.SetSource(ms);

            return bmi;
        }



Thank you.

Hi

There is not built-in method at the moment but maybe we can find a workaround.

Can you please tell me exactly how you create the BitmapImage in the first place?

Thanks

The byte array has been sent from the WCF service, converted to BitmapImage then set as a Source of image.

I am currently figuring out if I can be able to convert the sample string below (like an embedded data that can be viewed directly to the browser address) to byte array then send to the WCF service.

Re: BitmapImage to byte[]

Postby fangeles » Sat Feb 09, 2019 12:57 am

Have been solved this issue.


1. Get the INTERNAL_DataURL of BitmapImage (when the Source of Image is an image opened via FileOpenDialog)
2. Divide into parts (Max 8000 characters) by using the String.Substring method.
3. Send to WCF Service part by part (I can't configure the WCF to accept the whole string so the service refuses and returning a 500 error message that says entity is very large (the DataURL))
4. The WCF then consolidates the string parts, converts to byte array then saves to the database.

Here's the code to convert from DataURL to ByteArray.

Code: Select all

    private byte[] ImageStringToByteArray(String Data)
    {
        //Example of image DataURL
        //string str = "data:image/png;base64,/9j/4AAQSkZJRgABAQEAyADIAAD/2wBD....";

        var base64data = Regex.Match(Data, @"data:image/(?<type>.+?),(?<data>.+)").Groups["data"].Value;
        byte[] imageBytes = Convert.FromBase64String(base64data);


        return imageBytes;
    }


I don't think if this method is efficient, but this works for me.
