【问题描述】:
我正在使用以下代码将文本文件转换为 tiff,但是当文本文件内容以特殊字符开头时它不起作用。我不知道为什么它不起作用。你能请任何人帮我做这个任务吗
def main():
image = text_image('/Users/administrator/Desktop/367062657_1.text')
image.show()
image.save('contentok.tiff')
def text_image(text_path, font_path=None):
grayscale = 'L'
# parse the file into lines
with open(text_path) as text_file:
lines = tuple(l.rstrip() for l in text_file.readlines())
large_font = 20
font_path = font_path or 'cour.ttf'
try:
font = PIL.ImageFont.truetype(font_path, size=large_font)
except IOError:
font = PIL.ImageFont.load_default()
print('Could not use chosen font. Using default.')
pt2px = lambda pt: int(round(pt * 96.0 / 72))
max_width_line = max(lines, key=lambda s: font.getsize(s)[0])
test_string = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
max_height = pt2px(font.getsize(test_string)[1])
max_width = pt2px(font.getsize(max_width_line)[0])
height = max_height * len(lines) # perfect or a little oversized
width = int(round(max_width + 5)) # a little oversized
image = PIL.Image.new(grayscale, (width, height), color=PIXEL_OFF)
draw = PIL.ImageDraw.Draw(image)
vertical_position = 5
horizontal_position = 5
line_spacing = int(round(max_height * 1.0))
for line in lines:
draw.text((horizontal_position, vertical_position),
line, fill=PIXEL_ON, font=font)
vertical_position += line_spacing
c_box = PIL.ImageOps.invert(image).getbbox()
image = image.crop(c_box)`enter code here`
return image
错误:
错误: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf2 in 位置 18:无效的继续字节
【问题讨论】:
-
“不工作”是什么意思?有错误吗?文件是否生成但为空?它看起来与您的预期不同吗?
-
错误:UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf2 in position 18: invalid continuation byte
