python - PIL ImageDraw.textsize returns incorrect height -


i'm having issue pil's imagedraw module, draw.textsize method. method supposed take string , font, , return width , height string occupy when rendered in font. seems have lower bound on height returns, though: can't convince return lower 43. here's example (link) show i'm looking @ (bounding boxes drawn around text based on returned width & height), , here's code produced it:

from pil import image, imagedraw, imagefont # pil 1.1.7; python 2.6.6  im = image.open(r'c:\test\blank.png').convert('rgb') draw = imagedraw.draw(im)  textcolor = (0, 0, 0) x = 10 y = 3  fontsize in xrange(8, 51):     # other fonts behave same way     font = imagefont.truetype('arial.ttf', fontsize)      text = 'hello, world! size %d' % fontsize      width, height = draw.textsize(text, font=font)     print 'font size %d: %d x %d' % (fontsize, width, height)      bbox = [(x, y), (x+width, y+height)]     draw.rectangle(bbox, outline=textcolor)     draw.text((x, y), text, font=font, fill=textcolor)     y += height + 3  im.show()

once font gets size 38, bounding box stretches match correctly, before that, it's set static 43. question is, know why imagedraw behaving way, , know of way fix it? i'm working around issue setting:

width = min(width, fontsize+1)

...but that's not robust solution ever devised.

the basic issue seems pil super buggy , no longer supported. problem mentioned here isn't worst of (e.g. no 1 able replicate because it's hard install...).

in light of troubles seem rampant in pil 1.1.7, best solution seems to install pillow , move along. doesn't require code changes code runs pil (it's pil fork installs "pil" library), , seems vastly friendlier (and still active). commenters on question have confirmed, it's simple, trouble-free install , works it's supposed to.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
