Licenças de Código Aberto

O QrDeco se apoia em trabalho de código aberto, e é aqui que ficam os avisos exigidos: o motor de códigos de barras é a biblioteca Zint, distribuída sob a licença BSD-3-Clause, junto com os componentes com os quais o próprio site é construído.

Zint — o motor de códigos de barras

Cada simbologia que o QrDeco suporta é codificada pelo Zint, uma biblioteca de códigos de barras de código aberto mantida por Robin Stuart e compilada para rodar no navegador. O QrDeco incorpora essa compilação, salvo duas correções documentadas na camada de integração; nenhuma delas altera a licença. O aviso de direitos autorais e o texto completo da BSD-3-Clause da biblioteca e da compilação em WebAssembly são reproduzidos abaixo, como a licença exige.

O que isso significa para você

A BSD-3-Clause permite que qualquer pessoa use, estude, modifique e redistribua o motor, inclusive comercialmente, desde que os avisos acima o acompanhem. Suas exportações não são afetadas: a licença se aplica ao motor, e não aos códigos de barras que você cria com ele.

Como toda licença de código aberto, ela é oferecida sem garantia. Os limites de responsabilidade dos Termos de Serviço abrangem estes componentes também.

Outros componentes de código aberto

O site e o gerador são construídos com os componentes abaixo. Cada linha de direitos autorais é reproduzida do próprio arquivo de licença do pacote, e os textos compartilhados das licenças MIT e ISC vêm a seguir.
