1. 先从freeimage.dll中复制出函数的名字,就是以文本的方式打开freeimage.dll,查找FreeImage_Initialise,然后附近的一大段函数都复制下来,得到 free.txt文件

_FreeImage_AcquireMemory@12
_FreeImage_AdjustBrightness@12
_FreeImage_AdjustColors@32
_FreeImage_AdjustContrast@12
_FreeImage_AdjustCurve@12
_FreeImage_AdjustGamma@12
_FreeImage_Allocate@24
_FreeImage_AllocateEx@36
_FreeImage_AllocateExT@40

已上只复制了一小部分

2. 上代码批量替换

主要用正则表达式:

import re

funcs={}

for line in open('free.txt','r'):
    line = line.strip()
    #print line
    real = line
    key = line.split('@')[0]
    if key[0]=='_':
        key=key[1:]
    funcs[key]=line

#print funcs

text =  open('freeimage.nim','r').read()
#for x in re.findall('importc: "([\w\_\d]+)",',text):
#    print x
def dashrepl(matchobj):
    #print matchobj.group(1),type(matchobj.group(1))
    k= matchobj.group(1)
    return 'importc: "%s"' % funcs.get(k,k)

print re.sub('importc: "([\w\_\d]+)"',dashrepl,text)
