Image API

This library implements its own image format for OpenComputers with a simple loseless compression algorithm. It allows you to load and save pictures in .pic format, as well as to perform simple operations like string serialization/deserialization/scaling/transforming

Filesystem related methods

image.load(string path): table or boolean result, nil or string reason

Try to load an image from file system by given path. If loading was successful, the image table will be returned, it can be used for drawing on interface - for example, via GUI.image() method. If loading fails, false and reason will be returned. Reason describes why this happened - for example, the file system is read-only or there is not enough RAM to load image

local result, reason = image.load("test.pic")
if result then
  -- Do your stuff like GUI.image(1, 1, result)
else
 -- Image is broken or not enough RAM
end

image.save(string path, table picture, [, int encodingMethod = 6)]): boolean success, nil or string reason

Tries to save a given picture to a given path, using a specified encoding method. If no encoding method is given, it will be set to 6 automatically. Returns true if image was saved successfully, false and an reason if not (maybe filesystem is readonly or there's not enough disk space to save it)

local success, reason = image.load("test.pic")
if success then
  -- Image was saved
else
 -- Image wasn't saved because of "reason"
end
