如何在python界面显示图片

如何在python的GUI界面显示打开的图像文件，比如Tkinter(或者wxpython)，如何在界面显示出要打开的图片，需要什么控件吗？如果有，怎么调用？
能否给个具体实现的例子，可以运行的

Answer 1

wxpython:
# 使用wx.Image得到对象
bmp = wx.Image('bitmaps/image.bmp', wx.BITMAP_TYPE_BMP).ConvertToBitmap()
gif = wx.Image('bitmaps/image.gif', wx.BITMAP_TYPE_GIF).ConvertToBitmap()
png = wx.Image('bitmaps/image.png', wx.BITMAP_TYPE_PNG).ConvertToBitmap()
jpg = wx.Image('bitmaps/image.jpg', wx.BITMAP_TYPE_JPEG).ConvertToBitmap()

# 把它们显示出来
pos = 10
wx.StaticBitmap(frame, -1, bmp, (10, pos), (bmp.GetWidth(), bmp.GetHeight()))

pos = pos + bmp.GetHeight() + 10
wx.StaticBitmap(frame, -1, gif, (10, pos), (gif.GetWidth(), gif.GetHeight()))

pos = pos + gif.GetHeight() + 10
wx.StaticBitmap(panel, -1, png, (10, pos), (png.GetWidth(), png.GetHeight()))

pos = pos + png.GetHeight() + 10
wx.StaticBitmap(frame, -1, jpg, (10, pos), (jpg.GetWidth(), jpg.GetHeight()))

具体的请根据你的实际情况修改，最好去http://www.wxpython.org/download.php#binaries
下载wxpython和wxpython demo看看，这个demo很强大的。

　　代码：
　　# show a jpeg (.jpg) image using wxPython, newer coding style
　　# two different ways to load and display are given
　　# tested with Python24 and wxPython25 vegaseat 24jul2005
　　
　　import wx
　　import cStringIO
　　
　　class Panel1(wx.Panel):
　　""" class Panel1 creates a panel with an image on it, inherits wx.Panel """
　　def __init__(self, parent, id):
　　# create the panel
　　wx.Panel.__init__(self, parent, id)
　　try:
　　# pick a .jpg file you have in the working folder
　　imageFile = 'Moo.jpg'
　　data = open(imageFile, "rb").read()
　　# convert to a data stream
　　stream = cStringIO.StringIO(data)
　　# convert to a bitmap
　　bmp = wx.BitmapFromImage( wx.ImageFromStream( stream ))
　　# show the bitmap, (5, 5) are upper left corner coordinates
　　wx.StaticBitmap(self, -1, bmp, (5, 5))
　　
　　# alternate (simpler) way to load and display a jpg image from a file
　　# actually you can load .jpg .png .bmp or .gif files
　　jpg1 = wx.Image(imageFile, wx.BITMAP_TYPE_ANY).ConvertToBitmap()
　　# bitmap upper left corner is in the position tuple (x, y) = (5, 5)
　　wx.StaticBitmap(self, -1, jpg1, (10 + jpg1.GetWidth(), 5), (jpg1.GetWidth(), jpg1.GetHeight()))
　　except IOError:
　　print "Image file %s not found" % imageFile
　　raise SystemExit
　　
　　
　　app = wx.PySimpleApp()
　　# create a window/frame, no parent, -1 is default ID
　　# increase the size of the frame for larger images
　　frame1 = wx.Frame(None, -1, "An image on a panel", size = (400, 300))
　　# call the derived class
　　Panel1(frame1,-1)
　　frame1.Show(1)
　　app.MainLoop()
