Python OSError:尝试使用ImageFont.py时无法打开资源
我正在使用python生成令牌作为安全措施。代码如下:Python OSError:尝试使用ImageFont.py时无法打开资源,python,io,python-imaging-library,Python,Io,Python Imaging Library,我正在使用python生成令牌作为安全措施。代码如下: from PIL import Image, ImageDraw, ImageFont image=Image.new("RGBA",(220,20),(255,255,255)) image_base=ImageDraw.Draw(image) font = ImageFont.truetype("arial.ttf", 15) font.size = 16
from PIL import Image, ImageDraw, ImageFont
image=Image.new("RGBA",(220,20),(255,255,255))
image_base=ImageDraw.Draw(image)
font = ImageFont.truetype("arial.ttf", 15)
font.size = 16
image_base.text((80,0),emailed_password,(0,0,0),font=font)
image_bytes=BytesIO()
image.save(image_bytes,format='png')
logo_file = open('static\images\RCI_logo.jpg', 'rb')
logo_bytes = logo_file.read()
logo_file.close()
token_name='registration_token'
secret_code_attachment = MIMEImage(image_bytes.getvalue(), name = '{0}.png'.format(token_name))
secret_code_attachment.add_header('Content-ID', '<{0}>'.format(token_name))
secret_code_attachment.add_header('Content-Disposition', 'inline')
message.attach(secret_code_attachment)
logo_file_name='logo_file_svg'
logo_attachment = MIMEImage(logo_bytes, name = '{0}.jpg'.format(logo_file_name))
logo_attachment.add_header('Content-ID', '<{0}>'.format(logo_file_name))
logo_attachment.add_header('Content-Disposition', 'inline')
message.attach(logo_attachment)
html = 'some message'
html_attachment = MIMEText(html, 'html')
message.attach(html_attachment)
smtpObj.sendmail(sender,receiver,message.as_string())
我的理解是,ImageFont导致了这个问题,因为它无法加载正确的字体。我不知道如何修理它。更令人费解的是,在我把它放到服务器上之前,它一直在工作 遇到同样的问题,显然
font
文件无法通过PIL
找到
在font=ImageFont.truetype(“arial.ttf”,15)
中,找不到arial.ttf
解决方案是cd/usr/share/font/truetype
,找到可用的字体文件,然后用它替换“arial.ttf”
。(对于windows用户,字体文件位于C:\windows\font
)
