im not sure if this is a wxpython question or just a python question but i need help. im using img2py to embed pictures into a .py script. my question is how do i get them out? i tried to call the image with this:

dwpic = wx.Image(macroicons.getdwiconBitmap())

and this is the error i get:

TypeError: String or Unicode type required

could anybody help.

If you look at your macroicons.py file you will see that there three functions defined for each image:

E.g. in my file have an image called "bottle".

def getbottleBitmap():
return BitmapFromImage(getbottleImage())

def getbottleImage():
stream = cStringIO.StringIO(getbottleData())
return ImageFromStream(stream)

def getbottleIcon():
    icon = EmptyIcon()
    icon.CopyFromBitmap(getbottleBitmap())
    return icon

So, if you want an image just do:

dwpic = macroicons.getdwiconImage()

ok i changed the line from:

dwpic = wx.Image(macroicons.getdwiconBitmap())

to:

dwpic = macroicons.getdwiconImage()

im trying to put it in a sizer and i get this error:

TypeError: wx.Window, wx.Sizer, wx.Size, or (w,h) expected for item

A wx.Image instance is NOT a wx.Window. You need a control to show this image, e.g. a wx.StaticBitmap or a wx.BitmapButton etc.

What do you want to do with this image, what is it?

ya know your right i dont know what i was thinking, its a picture that i want to place on a panel that has a sizer, normally i would use a wx.Image() object and put where i want it in the ()
dwpic = wx.Image(basepanel))

but i cannot add the location into the () for this, is there a different way to add something to a panel?

huh? I don't think you can do that at all.

If you just want the image, use:

dwpic = macroicons.getdwiconBitmap()

Sizer.Add(wx.StaticBitmap(dwpic)

A wx.Bitmap is a platform native version of a bitmap.

A wx.Image is a platform neutral 24bit RGB ini-memory version of an image.

Neither can be displayed directly, you need to put a Bitmap in a control of some sort:

wx.StaticBitmap
wx.BitmapButtton

or a custom class of some sort, derived from wx.,Window or wx,panel, in which you draw the Bitmap yourself with DCs.

For lots more info.

Looks like Chris left out a couple parameters. Try something like wx.StaticBitmap(panel, -1, dwpic)

That's what I get for posting untested code. Try this (still untested!):

Sizer.Add(wx.StaticBitmap(parent, bitmap=dwpic)

Where parent is the wx.Widow that you want the Bitmap draw on. Every wx.Window constructor takes the parent as the first argument.

I've enclosed a little sample I put together that shows some of what you can do with a wx.StaticBitmap
