Some context:
I am trying to create an image from a stream.
The future image is currently loaded from memory into a buffer.
I have already tried things like:
image_stream = wx.MemoryOutputStream() # error: no attribute 'MemoryOutputStream'
image_stream.Write( image_buffer, buffer_size )
image = wx.Image( stream )
bitmap = wx.Bitmap( image )
Basically, wx.InputStream, wx.OutputStream and all of their ancestors are abstract-classes, I cannot instantiate them.
As you can see here and there, the documentation for their sub-classes seems to be missing.
It also follows from the error written in the above code that those classes are not implemented yet.
Is there a way to instantiate such stream in wxPython Phoenix? Or a workaround?
By the way, as I will write and then read from the stream, should it be an input stream, an output stream or one and then the other?
wxImage objects can be created directly from any object that supports the Python buffer interface, (bytearrays memoryviews, numpy arrays, etc.) See this section in the Migration Guide and also the __init__ and Create method overloads in the API documentation which have a parameter named data.
In addition, any Python "file-like object" can be automatically converted to the wx stream classes, so the Image constructor and Create method overloads which accept a stream parameters can use any compatible object (an open file, a StringIO, etc.) automatically, so you shouldn't have any need to make a wx.InputStream or wx.OutputStream.
