这是我用于代码的 png
test.png
它适用于一些图片而不适用于其他图片，这是给出错误的图片之一
import png
import array
point = (7, 10) # coordinates of pixel to be painted red
reader = png.Reader(filename='test.png')
w, h, pixels, metadata = reader.read_flat()
print(w, h, pixels, metadata)
pixel_byte_width = 4 if metadata['alpha'] else 3
pixel_position = point[0] + point[1] * w
new_pixel_value = (255, 0, 0, 0) if metadata['alpha'] else (255, 0, 0)
pixels[pixel_position * pixel_byte_width : (pixel_position + 1) * pixel_byte_width] = array.array('B', new_pixel_value)
output = open('img2.txt', 'wb')
writer = png.Writer(w, h, **metadata)
writer.write_array(output, pixels)
output.close()
当我 运行 它时，它打印：

以及打印后的错误：
Traceback (most recent call last):
File "C:\Users\user\Desktop\img EPIC compiler\img compiler.py", line 18, in <module>
writer = png.Writer(w, h, **metadata)
TypeError: Writer.__init__() got an unexpected keyword argument 'physical'
导致错误的原因是什么？
因此无法识别元数据中的值 'physical'，您需要做的就是对该值使用 .pop() 将其删除。所以如果你像这样使用它：
import array
point = (2, 10) # coordinates of pixel to be painted red
reader = png.Reader(filename='testt.png')
w, h, pixels, metadata = reader.read_flat()
metadata.pop('physical')
print(w, h, pixels, metadata)
pixel_byte_width = 4 if metadata['alpha'] else 3
pixel_position = point[0] + point[1] * w
new_pixel_value = (255, 0, 0, 0) if metadata['alpha'] else (255, 0, 0)
pixels[pixel_position * pixel_byte_width : (pixel_position + 1) * pixel_byte_width] = array.array('B', new_pixel_value)
output = open('img2.txt', 'wb')
writer = png.Writer(w, h, **metadata)
writer.write_array(output, pixels)
output.close()
它不再引发错误，并完成了工作。
这是我用于代码的 png test.png
它适用于一些图片而不适用于其他图片，这是给出错误的图片之一
import png
import array
point = (7, 10) # coordinates of pixel to be painted red
reader = png.Reader(filename='test.png')
w, h, pixels, metadata = reader.read_flat()
print(w, h, pixels, metadata)
pixel_byte_width = 4 if metadata['alpha'] else 3
pixel_position = point[0] + point[1] * w
new_pixel_value = (255, 0, 0, 0) if metadata['alpha'] else (255, 0, 0)
pixels[pixel_position * pixel_byte_width : (pixel_position + 1) * pixel_byte_width] = array.array('B', new_pixel_value)
output = open('img2.txt', 'wb')
writer = png.Writer(w, h, **metadata)
writer.write_array(output, pixels)
output.close()
当我 运行 它时，它打印：

以及打印后的错误：
Traceback (most recent call last):
File "C:\Users\user\Desktop\img EPIC compiler\img compiler.py", line 18, in <module>
writer = png.Writer(w, h, **metadata)
TypeError: Writer.__init__() got an unexpected keyword argument 'physical'
导致错误的原因是什么？
因此无法识别元数据中的值 'physical'，您需要做的就是对该值使用 .pop() 将其删除。所以如果你像这样使用它：
import array
point = (2, 10) # coordinates of pixel to be painted red
reader = png.Reader(filename='testt.png')
w, h, pixels, metadata = reader.read_flat()
metadata.pop('physical')
print(w, h, pixels, metadata)
pixel_byte_width = 4 if metadata['alpha'] else 3
pixel_position = point[0] + point[1] * w
new_pixel_value = (255, 0, 0, 0) if metadata['alpha'] else (255, 0, 0)
pixels[pixel_position * pixel_byte_width : (pixel_position + 1) * pixel_byte_width] = array.array('B', new_pixel_value)
output = open('img2.txt', 'wb')
writer = png.Writer(w, h, **metadata)
writer.write_array(output, pixels)
output.close()
它不再引发错误，并完成了工作。
