Maybe all of the Mac users of Hugin have already figured out how to get
multiblend (http://horman.net/multiblend/) to work - if you haven't you
should really try it, it's *much* faster than enblend, at least for the
kind of panoramas I create. But it's not optimized for OSX, and the build
instructions for Linux need some tweaking before they will work. So if
you're a Mac user like me and want to get it running, here are a few notes
on what I did:
I've made a few minor tweaks to the code to make it a bit easier to use:
1) In globals.cpp replace:
bool g_wideblend=false;
bool g_bgr=false;
with:
bool g_wideblend=true;
#ifdef __APPLE__
bool g_bgr=true;
#else
bool g_bgr=false;
#endif
I admit I'm not sure whether changing the default for g_wideblend makes any
significant difference, but it seems to work well for me. The #ifdef
eliminages
the need to specify "--bgr" as a command line option on Mac systems.
2) In multiblend.cpp replace:
else if (!strcmp(argv[i],"--bgr")) g_bgr=true;
else if (!strcmp(argv[i],"--wideblend")) g_wideblend=true;
with:
else if (!strcmp(argv[i],"--bgr")) g_bgr=!g_bgr;
else if (!strcmp(argv[i],"--wideblend")) g_wideblend=!g_wideblend;
The help text for the --wideblend option should also be updated to reflect
the change. Note that the changes in these two files are independent; if
you don't change globals.cpp then multiblend will retain its current
behavior for these two options.
To compile multiblend, you must have libtiff, libjpeg and libpng installed
(typically in /opt/local/lib - there are several ways to get these if you
don't already have them). You can then build multiblend with this command:
g++ -L/opt/local/lib -I/opt/local/include -msse2 -O2 multiblend.cpp -ltiff
-ljpeg -lpng -o multiblend
if you've installed libjpeg-turbo then change the "-ljpeg" to "-lturbojpeg"
- you might need to add another -L option depending on where it resides .
If you've got the various libs and header files in /usr/local or other
places rather than (or as well as) /opt/local then you should add the
appropriate "-L" and "-I" options to the command line.
There will be two "comparison of unsigned expression >= 0 is always true"
warnings generated, but these can be ignored.
Once multiblend is built and tested (try the command "./multiblend
--help"), you can go into Hugin's preferences and add it as an alternative
to enblend.
I haven't yet figured out how to propagate the ICC profile info from the
input files to the output file; enblend does this quite nicely, but I'm not
sufficiently fluent in C++ (I'm an old FORTRAN guy from way back...) to
know just what should be cut-n-pasted to add this to multiblend. If anyone
else would like to give it a shot, I'd love to see this!
