Reply To: How to display external images within Ctrlr?

In this post Atom says what LUA classes are bound to LUA (so they work in Ctrlr). He says that you need a pair of files (.h/.cpp) in order to bound a class. The link provided is from an old Ctrlr version, so we can compare between what was there years ago and what we have today:

Old Ctrlr: https://sourceforge.net/p/ctrlrv4/code/1511/tree/nightly/Source/Lua/JuceClasses/

Actual Ctrlr: https://github.com/RomanKubiak/ctrlr/tree/master/Source/Lua/JuceClasses

In the old Ctrlr there is “LImage.cpp” file that is not present now.

You can try in Ctrlr 5.3.201, in the console, the following:

img = Image()
what(img)

and you get this:

Object type [Image]

The one you are looking for seems to be class ImageFileFormat(), but I haven’t been able to make it work.
