c - Doxygen: How to redefine void -

-

i use library redefine void type (among others):

#define xx_void void

so when run doxygen on code like

/**  * @brief function description  */ xx_void foo(xx_void) {     /*...*/ }

i warning

file.c:10: warning: return type of member foo not documented

how can tell doxygen xx_void void there no return value ?

you can try macro_expansion tag:

macro_expansion

if macro_expansion tag set yes, doxygen expand macro names in source code. if set no, conditional compilation performed. macro expansion can done in controlled way setting expand_only_predef yes.

the default value is: no.

this tag requires tag enable_preprocessing set yes.

with macro_expansion set yes result after doxygen preprocessing becomes:

void foo(void) {   /* ... */ }

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

python - PIL cannot identify image file for io.BytesIO object -

-
i using pillow fork of pil , keep receiving error oserror: cannot identify image file <_io.bytesio object @ 0x103a47468> when trying open image. using virtualenv python 3.4 , no installation of pil. i have tried find solution based on others encountering same problem, however, solutions did not work me. here code: from pil import image import io # portion part of test code byteimg = image.open("some/location/to/a/file/in/my/directories.png").tobytes() # non test code databytesio = io.bytesio(byteimg) image.open(databytesio) # <- error here the image exists in initial opening of file , gets converted bytes. appears work else can't figure out why fails me. edit: databytesio.seek(0) does not work solution (tried it) since i'm not saving image via stream, i'm instantiating bytesio data, therefore (if i'm thinking of correctly) seek should @ 0. (this solution author himself. have moved here.) solution: # portion part ...

python - concatenating scipy matrices -
