File is not a windows bmp file

Running:
Mac OSX mountain Lion 10.8.3
Python 2.7.2
Pygame 1.9.2

I have a simple python pygame program that displays an image on the screen, this works great when I run it in my IDE. The problem comes when try to make it a standalone program using py2app I get the Error:

pygame.error: File is not a Windows BMP file

I did some research and found out that it is probably an error with pygame or SDL_image.framework so I reinstalled both and I get the same error. However, when I do use a BMP image the program works fine although I cannot use image formats such as .png or .jpg.

window.py:

import pygame,sys
from pygame.locals import *

pygame.init()
size=[700,500]
screen=pygame.display.set_mode(size)
clock=pygame.time.Clock()

img = pygame.image.load("Images/img.png") # Error generated here

# -------- Main Program Loop -----------
while True:
    # ALL EVENT PROCESSING SHOULD GO BELOW THIS COMMENT
    for event in pygame.event.get():
        if event.type == QUIT:
            isRunning = False
            pygame.quit()
            sys.exit()

    screen.blit(img,(300,300))

    pygame.display.flip()
    clock.tick(20)

If it is of any use, here is my setup.py file:

from setuptools import setup

APP = ['window.py']
DATA_FILES = [('', ['images'])]
OPTIONS = {'argv_emulation': True}

setup(
      app=APP,
      data_files=DATA_FILES,
      options={'py2app': OPTIONS},
      setup_requires=['py2app'],
      )

Problem Solution for 2.7.2:

Turns out my pygame files got or were corrupted. To solve the problem I replaced my old pygame files within the application with new pygame files. The pygame folder in the application is located at «app.app/Contents/Resources/lib/python2.7/lib-dynload». Replace the old pygame folder with this one and hopefully it will work:

Other Solution

I downloaded python version 2.7.5 for mac and this simply fixed all errors from not being able to load the pygame mixer to being able to load jpg and png images.

Environment:

You can get some of this info from the text that pops up in the console when you run a pygame program.

• Operating system Mac M1:
• Python version Python 3.9.1 :
• SDL version SDL 2.0.14:
• PyGame version 2.0.2.dev1:

Current behavior:

I just build Pygame use this command below in my arm m1 Mac, everything almost running no error in this machine

brew install sdl2 sdl2_gfx sdl2_image sdl2_mixer sdl2_net sdl2_ttf
git clone https://github.com/pygame/pygame.git
cd pygame
python setup.py -config -auto -sdl2
python setup.py install

but when I run my code, It report a error like can’t read .png file, and then I convert this png file to bmp, It’s running success

Screenshots

Test code

If possible add a simple test program that shows the problem described in this report.

import pygame
pygame.image.load('chessboard.png')

Game().run()

Я попытался найти другие вопросы, основанные на этой ошибке, но, похоже, ничего не работает …

Я использую macOS Catalina, Python 3.8.5 и Pygame 1.9.6.

На данный момент я не профессионал в использовании Python, поэтому, пожалуйста, постарайтесь четко объяснить!

Спасибо!

Return to “Python”

There are many users with problem regarding loading pygame images, be it jpeg or png.

«File is not a Windows BMP file» — not really helpful in this case

As per pygame documentation, to check if extended image support was enabled you should do:

>>> print(pygame.image.get_extended())
0

Zero means it isn’t, but in my case I knew it was enabled and if you don’t — it probably is.

Road to enlightenment

I’ve opened my Python3.3 installation site-packages dir (your path may vary): /usr/lib/python3.3/site-packages/pygame/

there was image.so file which is a pygame.image module inside python interpreter,
but what about other similar file — imageext.so? Both use libpng and image.so imports successfully.

So what happens if I try to import imageext?

Well, that happens:

>>> import pygame.imageext
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: libpng15.so.15: cannot open shared object file: No such file or directory

Now, that is a core of this problem — libpng version has changed and pygame depends on older one.

How to fix

There are 3 ways i can think of:

Quick one — You could symlink expected patch to current libpng but its ugly way and may yield unpredictable results ™.

Somewhat good — You can downgrade system libpng version to match expected

Best one — Fix everything! Recompile things if your system allows it — I’m using Gentoo so it is the way I choose

So, for the best way:

On any distribution — to list libs depending on missing file run:

grep -R libpng15.so.15 /usr/lib/*

Command could yield something like that:

Plik binarny /usr/lib/libSDL_image-1.2.so.0 pasuje do wzorca
Plik binarny /usr/lib/libSDL_image-1.2.so.0.8.4 pasuje do wzorca
Plik binarny /usr/lib/libSDL_image.so pasuje do wzorca

The sdl-image package got broken, and pygame depends on it.

Now, we have to just reinstall/update sdl-image package and everything should work. To the next libpng update
