worked great. I am a bone head I forget what the ranges were for the RGB colors.]]> Tue, 03 Aug 2010 21:22:02 +0000 http://www.quickpdf.org/forum/shade-background_topic1527_post6782.html#6782 <![CDATA[Shade background : Hi Wayne!I&#039;ve taken some...]]> http://www.quickpdf.org/forum/shade-background_topic1527_post6781.html#6781 Author: Ingo

Hi Wayne!

I've taken some code out of one of my components:
//. . .
var
colr, colg, colb : Double;

  if ( rgb1 = '' ) then
     rgb1 := '1,0';
  if ( rgb2 = '' ) then
     rgb2 := '1,0';
  if ( rgb3 = '' ) then
     rgb3 := '1,0';

  colr := StrToFloat(rgb1);
  colg := StrToFloat(rgb2);
  colb := StrToFloat(rgb3);

  QP2 := TQuickPDF0717.Create;
  try
     QP2.UnlockKey('...');
//   . . .
     QP2.SetFillColor(colr,colg,colb);
//   . . .
     QP2.DrawText(...);
//   . . .
  Finally
     QP2.SaveToFile...;
     QP2.Free;
  end;
//. . .
 
Please keep in mind that we're talking about RGB-colors.
The max-value for R, G and B is 1!
...(1.0, 1.0, 1.0) means white
...(0.0, 0.0, 0.0) means black.
Make some tests with values below 1.0 ...

Cheers, Ingo

I want to draw some text (in black) then fill the background with a light gray color.
Can anyone give me an example of how to do that.
I have tried transparency and setfillcolor and nothing seems to work.
Here is a snippet of my code.
 
    x := LeftMargin ;
    PDF.DrawText(x, y, 'Form ID') ;
    PDF.DrawText(x+wFormID, y, 'Form Description') ;
    y := y + LineHeight ;
    PDF.DrawText(x, y, 'Pages') ;
    PDF.DrawText(x+wFormID, y, 'DCN') ;
    y := y + (LineHeight div 4) ;
    PDF.DrawLine(x, y, PDF.PageWidth-RightMargin, y) ;
    // Here is where I want to shade the background and I have no idea what colors make light gray
    PDF.SetFillColor(10,10,10) ;
    PDF.SetTransparency(70) ;
    PDF.DrawBox(LeftMargin, SaveY, PDF.PageWidth-LeftMargin-RightMargin, y-SaveY, 2) ;
    PDF.SetTransparency(0) ;
    y := y + LineHeight ;
