Width property is not parsed inside CSS body

Hello,

Using this code to convert HTML to PDF via SynPdf component, the PNG image is not rendered ; JPG does.

function THtmlPager.SynPdf:TBytes;
label
  Clear;
var
  OK     : Boolean;
  Size   : TSize;
  PDF    : TPdfDocumentGDI;
  Stream : TMemoryStream;
begin
  PDF  := nil;
  PDF  := TPdfDocumentGDI.Create;
  OK   := True;
  Size := FullDisplaySize(Width);
  try
    {PDF.UseUniscribe     := True;}
    PDF.DefaultPaperSize  := psUserDefined;
    PDF.ScreenLogPixels   := Screen.PixelsPerInch;
    PDF.Info.Author       := EditorOrgName;
    PDF.Info.CreationDate := Now;
    PDF.Info.Creator      := ApplicationName;
    PDF.Info.Keywords     := '';
    PDF.GeneratePDF15File := True;
    PDF.DefaultPageWidth  := Round(Size.cx*72/PDF.ScreenLogPixels);
    PDF.DefaultPageHeight := Round(Size.cy*72/PDF.ScreenLogPixels);
    PDF.AddPage;
    HTMLPaint(PDF.VCLCanvas,Rect(0,0,Size.cx,Size.cy));
  except
    OK := False;
  end;
  if (not OK) then goto Clear;
  Stream := TMemoryStream.Create;
  try
    PDF.SaveToStream(Stream);
  except
    Stream.Clear;
  end;
  SetLength(Result,Stream.Size);
  Stream.Position := 0;
  Stream.Read64(Result,0,Length(Result));
  FreeAndNil(Stream);
Clear:
  if Assigned(PDF) then FreeAndNil(PDF);
end;

Would real rendered Width and Height determined without the default width parameter provided to FullDisplaySize function?

Would margins set to 0 so document and control widths will be identical by introducing paraemetrs to the function:

procedure THtmlViewer.UpdateSize;
begin
  if AutoSize then
  begin
    HScrollBar.Visible := False;
    VScrollBar.Visible := False;
    SetBounds(Left, Top, ScrollWidth + 2, MaxVertical + 2);
  end;
end;

which would be:

procedure THtmlViewer.UpdateSize;
begin
  if AutoSize then
  begin
    HScrollBar.Visible := False;
    VScrollBar.Visible := False;
    SetBounds(Left, Top, ScrollWidth + WidthMargin, MaxVertical + HeightMargin);
  end;
end;

Best regards.

Hello, The Width attribute is not parsed inside CSS body (210mm). The real Width of the html is set ignoring this attribute.

<meta content="text/html; charset=utf-8" http-equiv="Content-Type"/>
   <title>Residence information</title>
   <style>
       body {
           font-family: "Courier New", Courier, monospace;
           font-size: small;
           position: absolute;
           width:210mm;
           margin:0mm;
       }

Please note that the Height is set to its correct value.

Best regards.

Sorry,

The PNG rendering problem is caused by the SynPdf component! https://github.com/synopse/SynPDF
