RingStbImage 拡張機能の関数一覧です。

用例:

.. code-block:: ring

	# ライブラリの読み込み
		load "stbimage.ring"
	# 画像の情報
		width=0	height=0 channels=0
	# Ring はプログラム終了後に cData を自動的に解放します
		cData = stbi_load("ring.jpg",:width,:height,:channels,STBI_rgb)
	# 画面へ結果を表示
		? "Size (bytes): " + len(cData)
		? "Width : " + width
		? "Height: " + height
		? "Channels: " + channels

実行結果:

.. code-block:: ring

	Size (bytes): 557371
	Width : 563
	Height: 330
	Channels: 3
