New issue 15 by yarosla...@gmail.com: Wrong size with FT_LOAD_MONOCHROME
flag
http://code.google.com/p/freetype-py/issues/detail?id=15

When loading with monochrome, glyph bitmap has much smaller size than
reported width*height. In the example below, you get following output:

Dimensions: 7, 39, total size: 273
Dimensions: 7, 38, total size: 76

import sys, pickle, numpy, Image
from freetype import *

face = Face('1550.ttf')
face.set_char_size(48*64)

def load_glyph(flags):
face.load_glyph(3, flags)
bitmap = face.glyph.bitmap
w,h = bitmap.width, bitmap.rows
print "Dimensions: %d, %d, total size: %d"%(w, h,len(bitmap.buffer))

load_glyph(FT_LOAD_RENDER)
load_glyph(FT_LOAD_RENDER|FT_LOAD_MONOCHROME)

I think it is ok since monochrome glyphs are encoded using 1 bit per pixel
(not byte). So 76 should correspond more or less to the right size (there
is also some padding involved).

Have a look at:
