How to create a wx.Image object from data in memory?

Question

I am writing a GUI application in Python using wxPython and want to display the image in a static control ( wx.StaticBitmap ).

I can use wx.ImageFromStream to load an image from a file, and this works fine:

 static_bitmap = wx.StaticBitmap(parent, wx.ID_ANY) f = open("test.jpg", "rb") image = wx.ImageFromStream(f) bitmap = wx.BitmapFromImage(image) static_bitmap.SetBitmap(bitmap) 

But, what I really want to do is create an image from the data in memory. So if I write

 f = open("test.jpg", "rb") data = f.read() 

how can i create a wx.Image object from data ?

Thank you for your help!

Answer 1

You can use StringIO to transfer the buffer to a memory file object.

 ... import StringIO buf = open("test.jpg", "rb").read() # buf = get_image_data() sbuf = StringIO.StringIO(buf) image = wx.ImageFromStream(sbuf) ... 

buf can be replaced with any data string.

Since you use Duck Typing in Python, you can write your own stream class and pass an instance of this class to ImageFromStream. I think you only need to implement the read method and make it return your data.
