Background Image file

wxPython Users
1

Hello everyone,

I am trying to build a .exe app using pyinstaller to make it standalone.

I have an issue with the background image, I am using wxPython for the gui.

My background image file is not in the .exe, it has to be in the folder where my .exe is else my program is not working.

Every other dll, icon file, whatever else my program needs is in the standalone .exe.

If anyone would know how to integrate my image file to make sure this is a standalone .exe this would be perfect.

The important part of my code for this is the following:

class MainPanel(wx.Panel):
        """"""

        def OnClose(self, e):
                parse.parsing()
        def __init__(self, parent):
                """Constructor"""
                wx.Panel.__init__(self, parent=parent)
                #self.SetBackgroundStyle(wx.BG_STYLE_CUSTOM)
                self.frame = parent

                sizer = wx.BoxSizer(wx.VERTICAL)
                hSizer = wx.BoxSizer(wx.HORIZONTAL)

                cbtn = wx.Button(self, label='Configure', pos=(196, 144))
                cbtn.Bind(wx.EVT_BUTTON, self.OnClose)

                self.SetSizer(hSizer)
                self.Bind(wx.EVT_ERASE_BACKGROUND, self.OnEraseBackground)

        def OnEraseBackground(self, evt):
                """
                Background image
                """
        # yanked from ColourDB.py
                dc = evt.GetDC()

                if not dc:
                        dc = wx.ClientDC(self)
                        rect = self.GetUpdateRegion().GetBox()
                        dc.SetClippingRect(rect)
                dc.Clear()
                bmp = wx.Bitmap("pf_bg.png")
                dc.DrawBitmap(bmp, 0, 0)

For information when compiling with pyinstaller I use the following:
python pyinstaller.py --version-file=version.txt -F --noconsole --icon=ic.ico -n blabla gui.py

When I try to open my .exe without my image file in the folder I have the error in the attached file.

I am not sure if I have to fix something with wx or pyinstaller.

Everything is compile on win7(64) with python 2.6.6

Thanks,

Antoine

encode it as base64 and paste the resultant string into a variable somewhere, then load that into an image and convert to a bitmap.

I’ve attached some example code, which I improved based on the following link, to get rid of the intermediate file they were using:

wallpaper/tile a wxPython panel using a base 64 encoded image string

“”"

the image string is created with this simple Python code

and the string is then copied and pasted to the program

import base64

jpg_file = “BG_Egypt.jpg”

print \

“jpg_b64=‘’'\\n” + base64.encodestring(open(jpg_file,“rb”).read()) + “‘’'”

“”"

import wx

import base64

import StringIO

BG_Egypt_jpg_b64=‘’'\

wxPython ships with utilities to do somethign much like this -- lok for teh
img2py script.

And it is, indeed, really handy particularly for bundling up with py2exe
and the like.

Hello,

I managed to archive what I was looking for with img2py.

Thanks for the help

I am trying to build a .exe app using pyinstaller to make it standalone.

For information when compiling with pyinstaller I use the following:
python pyinstaller.py --version-file=version.txt -F --noconsole --icon=ic.ico -n blabla gui.py

When I try to open my .exe without my image file in the folder I have the error in the attached file.

I am not sure if I have to fix something with wx or pyinstaller.

Everything is compile on win7(64) with python 2.6.6
