display monochromatic images wxPython

[wongjoekmeu]

Dear All,
I want to write a GUI program with wxPython displaying an image. But
the image I have is monochromatic. When I retrieve the data from the
image I end up with a list of integer. Starting from a list of integer
and knowing the width and height of the image, how do I display such
an image on a wx panel or frame ? I have had a look at the wxPython
demo but there I see only images where the data is a list of tuple
consisting of r,g ,b values. Is there are function where I directly
can input the list of array and let it display the image ?
Thanks in advance

You should be able to create a wx.StaticBitmap object and then set the
photo on it. Something like this:

<code>

# create a blank image holder
img = wx.EmptyImage(2 40,240)

self.myImageObj = wx.StaticBitmap (self, wx.ID_ANY,
wx.BitmapFromIm age(img))
self.myImageObj .SetBitmap(wx.B itmapFromImage( img))

# refresh the widgets
self.Refresh() # where "self" is a wx.Frame

</code>

If that doesn't make sense or doesn't work in your case, please re-
post the question to the wxPython's User group:

I think that RGB colors with the same amount of R,G, and B levels always
result in some shade of gray. If so, you could try building your image
data by convering each numver in a triplet of equal numbers.

Then be sure to check out the wxPython demo application. It displays
lots of images.
