Question

I’m trying to produce a system which takes an image in OpenCV, writes it to XML, reads it from XML, and displays it in an Image control in a WPF application.

The problem I’m having is that I’m unclear as to how .NET classes (e.g. BitmapImage) process images from a byte array. I’ve tried a number of methods and gotten various errors – too numerous to post unless required.

I was wondering if someone could point me in the right direction regarding this? What I want to know is how does the data need to be presented to a .NET object in order to display it in an Image control?

Thanks in advance for your help – it is much appreciated.

EDIT: I expect what I need to do is convert the XML into a byte array and use that, along with a definition of the format, to instantiate a BitmapImage object or equivalent to use as source for the Image control. What I’m not sure of is how to do this.

Answer 1

I found that the issue was (presumably) that I wasn’t Base64 encoding the XML data before writing it. Thus the solution is to Base64 encode the data before writing to XML, Base64 decoding it on the other side, reading the data as a byte array and using that to instantiate a MemoryStream and then a BitmapImage object.

Thanks for your help everyone.
