I have an array of this struct (sd_image_t*) as the return value of a function:
sd_image_t*
typedef struct { uint32_t width; uint32_t height; uint32_t channel; uint8_t* data; } sd_image_t;
In C++ I can call sd_image_t[n].data while with SWIG created Lua bindings I can only call sd_image_t.data (which seems to be a pointer to all data of the struct). Is there a way to wrap it, so that I can call it like in C++? Could %naturalvar help in my case? https://www.swig.org/Doc1.3/SWIGPlus.html#SWIGPlus_member_data Here I tried to describe my issue too: https://forum.openframeworks.cc/t/swig-lua-binding-for-accessing-elements-of-an-image-array/43429
sd_image_t[n].data
sd_image_t.data
%naturalvar

You're looking at a really ancient version of the manual there (the last SWIG 1.3.x release was in 2009, the current release is SWIG 4.2.0).
See https://www.swig.org/Doc4.2/Lua.html#Lua_typemap_arrays for documentation discussing wrapping arrays for Lua.
Sorry, something went wrong.
Question and answered so closing.
