これ以降に記述されている内容は、このようなコンピューター・プログラムを制作した、というような事を、ただ、述べているに過ぎない。
以下の記述を読んだ人が、それを単に参考にする、というのであれば、問題は無いと、思われる。
しかし、記述されている内容に沿って、その人が、そこに記されているのと同様の制作や作業を行った際に、その制作、作業、コンピューターの作動の結果、使用されたコンピューター等、様々な方面において、何らかの問題が発生しない、という保証は、全くない。
その制作、作業、コンピューターの作動の結果、その人や、その人が所属している組織、その人が使用した様々な機器、インフラストラクチャー等の、身の上にどのような事が起ころうとも、私は一切、責任を負わない。
このプログラムは、Python(パイソン) 言語を使って、記述されている。
－－－－－－－－－－
既に発表ずみの、下記プログラムに、機能追加した。
Python(パイソン) ,OpenCV2 ,ソースプログラムリスト あり ,プログラム作ってみた ,[画像処理, OpenCV2 使用] を 行う
追加した主な機能は、下記である。
画像中に、多角形（内部をぬりつぶしした）を、挿入したい、というような時に、使える機能
( def insert_polygon_filled_into_ImageData )
OpenCV2 の [ fillConvexPoly ] を使って、この機能を実現している。
エラー処理に関しては、下記のコンテツに記述したものを利用している。
