Exemplos

Use os System.Drawingnamespaces , System.Drawing.Printing, e System.IO para este exemplo.

O exemplo de código seguinte define as definições padrão de página de um documento para margens de 1 polegada de cada lado.

void Printing()

              has been set to the path of the file to print. */

Observações

A Margins classe é usada para manipular a largura das margens em PageSettings e PrintController. MarginsConverter é o descritor de tipo para esta classe.

Left, Right, Top, e Bottom são propriedades que definem as margens. Clonecria um .Margins Equals determina se outro objeto tem as mesmas dimensões que um Margins.

Para mais informações sobre impressão, consulte a visão geral do System.Drawing.Printing namespace.
