image.new is a function that is part of the image APIs.

This has been introduced in TI-Nspire OS 3.0 (Changes).

Updated in ApiLevel 2.3 (OS 3.6).

Syntax

myImage = image.new(imgData)

For ApiLevel < 2.3 (OS < 3.6) :

Parameter Type Description
imgData
string The TI.Image-formatted string

For ApiLevel >= 2.3 (OS >= 3.6) :

Parameter Type Description
imgData
TI.ResourceHandle The image resource (as created by the SDK)

Example

-- For ApiLevel < 2.3 (OS < 3.6) :
img = image.new("\002\000\000\000\002\000\000\000\000\000\000\000\004\000\000\000\016\000\001\000\255\255\255\255\255\255\255\255")

-- For ApiLevel >= 2.3 (OS >= 3.6) :
img = image.new(_R.IMG.img_1)

-- Example from Jim Bauwens: 
-- Of course if you have many images you just could use a for loop to do that for every image :
myImages = {}
for img_name, img_resource in pairs(_R.IMG) do
         myImages[img_name] = image.new(img_resource)
end
-- that way you could do
gc:drawImage(myImages.img_1, 10, 10)
