Global variables

Here are some global variables in PixelsWorld:

globalvars.lua

depth -- Dpc: 8,16,32
width -- Width input image
height -- Height input image
time -- Current time(s)
duration -- Duration of current layer(s)
inpoint -- Inpoint of current layer(s)
compTime -- Comp current time(s)
pluginFolder -- The plugin folder(utf8)
projectName -- Project name(utf8)
projectPath -- Project path(utf8)
projectFolder -- Project folder(utf8)
ds_width -- Width of downsampled input image
ds_height -- Height of downsampled input image
origin_x -- The X coordinate of left top corner of input image in the layer coordinate. 
origin_y -- The Y coordinate of left top corner of input image in the layer coordinate.

Globals can be printed by using following code:

printGlobals.lua

version3()
in2out()
for k, v in pairs(_G) do
    print(k)
    print(" " .. type(v) , .5,.5,.5)
    print(" ".. tostring(_G[k]),0,1,1)
    println("")
end
