ToByteArray() Issue

Oct 15, 2011 at 7:07 AM

 WriteableBitmap bitmap = new WriteableBitmap( 500, 50);




bitmap.Render(uielement, uielement.RenderTransform);


byte[]  arr= ToByteArray(bitmap); // WritableBitmapEx's method

1. Hi my requirement is to capture the image of a UIElement and convert into byte[] and store in database.

2. Then the byte array can be accessed in HTML to display as image.

I am done with the first step, but the converted byte[] cannot be coverted to image in html/aspx.

The ToByteArray returns the raw ARGB data. Your browser expects a jpeg or png format.

I blogged about how to encode a WriteableBitmap as JPEG here
