C#バーコードCode 128アルゴリズムの生成
60584 ワード
ストライプはいろいろありますが、Code 128は比較的よく使われるもので、高密度のバーコードです. CODE 128符号は、ASCII 0からASCII 127までの128文字を表すことができるので、128符号と呼ばれる.数字、アルファベット、記号が含まれています. Code 128には、A(数字、大文字、制御文字)B(数字、大文字、文字)C(2桁) の3つの異なるバージョンがあります. CODE 128コードは、より包括的な文字(数字、アルファベット、記号)を表すことができ、同じ長さのバーコードに収容できる文字の長さが長い(高密度)ため、かなり広く応用されている.
ネット上でいくつかのアルゴリズムを探して、公共のクラスに整理しました.
