Lua/Scripts:Standard/Lualib/Capmode

CHDK/LUALIB/capmode.lua

This is a standard lua module included in the full CHDK distribution. It provides convenient access to the capture mode control functions, as well as the ability to specify capture modes by their names.

Modes names may be found in CHDK/LUALIB/GEN/modelist.lua. These are the same as the enum values in include/modelist.h, minus the MODE_ prefix

WARNING This feature is still under development. The available mode numbers, their mapping to canon modes, and their symbolic names may change in the next several CHDK revisions. This notice will be removed when they are finalized.

Using the module

This module does not set any global variables. Instead, you must assign the return value of require to the variable through which you will access the modules interface.
