QrCode em delphi 7


Pierre Romão

Question

Olá pessoal, estou tentando exibir e imprimir uma imagem QrCode no Delphi 7.  Tenho um artigo sobre o assunto inclusive com código fonte, mas o mesmo dá o seguinte erro:

Build
  [Error] Main.pas(94): Undeclared identifier: 'TPngImage'
  [Error] Main.pas(98): Missing operator or semicolon
  [Error] Main.pas(105): Missing operator or semicolon
  [Error] Main.pas(114): Missing operator or semicolon
  [Fatal Error] DelphiQrCode.dpr(6): Could not compile used unit 'Main.pas'
 

Mesmo declarando a classe PngImage na sessão USES o erro continua.

Alguém pode me ajudar?
