我编写了一个Python脚本,用于从字体中绘制字符,导出并将其发送到CGI界面进行显示。但是,它不起作用。代码如下:
#!/usr/bin/python
# coding: UTF-8
def getStringImage(text, font, size=40, color=[0,0,0]):
import Image, ImageDraw, ImageFont
img = Image.new("RGBA", (size, size), "white")
draw = ImageDraw.Draw( img )
draw.ink = color[0] + color[1]*256 + color[2]*256*256
font = ImageFont.truetype(font, size)
draw.text( (0,0), text, font=font )
data = img.getdata()
newData = list()
for item in data:
if (item[0], item[1], item[2]) == (255, 255, 255):
newData.append((255, 255, 255, 0))
else:
newData.append((item[0], item[1], item[2], 255))
img.putdata(newData)
return img
text = "" # U+E010
font = "hzcdp01b.ttf"
size = 100
color = [0, 0, 0]
img = getStringImage( text.decode('UTF-8'), font, size, color )
print 'Content-Type: image/png'
print 'Content-Disposition: inline; filename="image.png"'
print
import cStringIO
f = cStringIO.StringIO()
img.save(f, "png")
f.seek(0)
print f.read()
上面使用的字体是从这个系统中提取的:http://j.mp/14y6MAL,这是单个备份文件:http://j.mp/122PGLe
如果使用其他字体(例如“mingliu.ttc”与char“人”),它可以正常工作。

确保要显示的字符实际映射到字形。查看hzcdp01b.ttf
时,它似乎没有字符映射表:
