wxpython->图片显示不完整
wxpython->图片显示不完整

主要是运行后显示的图片仿佛边缘被裁减过的样子。谁能解释一下原因？

#!/usr/bin/env python

"""Hello, wxPython! program."""

import wx

class Frame(wx.Frame):
    """Frame class that displays an image."""

    def __init__(self, image):
        """Create a Frame instance and display image."""
        temp = image.ConvertToBitmap()
        size = temp.GetWidth(), temp.GetHeight()
        wx.Frame.__init__(self, parent=None, id=-1, title='Hello, wxPython!',
                 pos=wx.DefaultPosition,size=size)
        self.panel = wx.Panel(self)
        wx.StaticBitmap(parent=self.panel, bitmap=temp)
        self.Centre()
        
class App(wx.App):
    """Application class."""

    def OnInit(self):
        image = wx.Image('img.jpg', wx.BITMAP_TYPE_JPEG)
        self.frame = Frame(image)
        self.frame.Show()
        self.SetTopWindow(self.frame)
        return True

def main():
    app = App()
    app.MainLoop()

if __name__ == '__main__':
    main()

[解决办法]
考虑你有很多控件的时候，自己算很麻烦吧，所以一般是建议采用sizer方式布局方式，让程序自己去计算，譬如你的代码可以改成下面，不用管图片大小，只要求panel占满空间：

    def __init__(self, image):
        """Create a Frame instance and display image."""
        temp = image.ConvertToBitmap()
        #~ size = temp.GetWidth(), temp.GetHeight()
        wx.Frame.__init__(self, parent=None, id=-1, title='Hello, wxPython!')#, pos=wx.DefaultPosition,size=size)
                         #~ pos=wx.DefaultPosition,size=size)
        self.panel = wx.Panel(self)
        wx.StaticBitmap(parent=self.panel, bitmap=temp)
        sizer = wx.BoxSizer()
        sizer.Add(self.panel, 1, wx.EXPAND)
        self.SetSizerAndFit(sizer)
        self.Centre()
