THPDFPage.SetGrayColor Method

调用 SetGrayColor 设置填充和描边颜色值。此函数等同于同时调用两个函数以相同值调用 SetGrayFillColor 和 SetGrayStrokeColor

代码示例

program Rectangle;
{$APPTYPE CONSOLE}
uses
    SysUtils, Graphics, Classes, HPDFDoc;

var
    HPDF: THotPDF;

begin
    HPDF := THotPDF.Create(nil);
    try
        HPDF.AutoLaunch := true;                                 // PDF file will be shown automatically
        HPDF.FileName := '\Rectangle.pdf';                   // Set PDF filename
        HPDF.BeginDoc;                                               // Create PDF file
        HPDF.CurrentPage.SetGrayColor ( 0.525 );          // Set gray color
        HPDF.CurrentPage.Rectangle( 10, 10, 100, 100 ); // Draw rectangle
        HPDF.CurrentPage.FillAndStroke;                       // and fill and stroke
        HPDF.EndDoc;                                                  // Close PDF file
    finally
        HPDF.Free;
    end;
end.
