Make thumbnails for jpeg images in pure Lua?

Question

Lua -> Is it possible to Shrink Larger Image ?

I need it to make thumbnails for jpeg images.

I don't need a "binding". Is there any module writed in pure Lua ? Is it difficult to write one ?

I have found these:

• https://github.com/tnodir/luafreeimage
• http://www.tecgraf.puc-rio.br/im/
• http://ittner.github.com/lua-gd/manual.html#intro

but they all use C libraries. Also, do you think it is possible to read Exif Data of Photographs in pure LUA ?

Answer 1

It is possible, but no one has done it, because it is difficult and kindof pointless, since Lua interfaces very nicely with C.
