Converting an in memory GIF to bitmap

wxPython Users
1

Hi All,

I know how to display a GIF when it is to be loaded from a file but
now need to do the same with a GIF that has been retrieved from a
database. I have spent all afternoon trying various things but nothing
works. Can someone point me in the right direction.

Thanks, Normi

You probably just need to do something like this:

<code>

import wx, cStringIO

# open your database connection
# read the data into a string or something
data = dbConn.someQuery()
img = wx.ImageFromStream(cStringIO.StringIO(mapData))
imgCtrl = wx.StaticBitmap(imgPanel, wx.ID_ANY, wx.BitmapFromImage
(img))

</code>

Hope that gets you going at least.

See wx.ImageFromStream and cStringIO.StringIO to use the database field as file stream.
