我正在写一个简单的图片编辑器。它使用PPM文件。据我所知,我觉得我的代码应该可行。但是,我收到此错误
Traceback (most recent call last):
File "/home/zach/Downloads/piceditor (1).py", line 84, in <module>
main()
File "/home/zach/Downloads/piceditor (1).py", line 69, in main
image = Image(Point(100,100), filename)
File "/home/zach/Downloads/graphics.py", line 770, in __init__
self.img = tk.PhotoImage(file=pixmap[0], master=_root)
File "/usr/lib/python3.1/tkinter/__init__.py", line 3272, in __init__
Image.__init__(self, 'photo', name, cnf, master, **kw)
File "/usr/lib/python3.1/tkinter/__init__.py", line 3228, in __init__
self.tk.call(('image', 'create', imgtype, name,) + options)
_tkinter.TclError: couldn't recognize data in image file "pig.ppm"
我的代码看起来像这样
def main():
print("Image Editor")
print()
filename = input("name of image file: ")
print()
with open(filename) as f:
formatind = f.readline()
width, height = [int(x) for x in f.readline().split()]
colordepth = f.readline()
array = []
for line in f:
array.append([int(x) for x in line.split()])
win = GraphWin("Image Editor!", width, height)
image = Image(Point(100,100), filename)
Display(image, array, width, height, win)
inf.close()
win.getMouse()
win.close()
main()
我的显示功能看起来像这样
def Display(image, array, width, height, win):
for i in range(width):
for j in range(0, height, 3):
colors = color_rgb(array[i][j], array[i][j+1], array[i][j+2])
image.setPixel(i, j, colors)
image.draw(win)
return
这是使用
的ppm文件P3

我不能为我的生活弄清楚为什么它不会识别文件中的数据。
任何帮助都会很棒。感谢
