Can't Find Declaration for TTeePDFPage

I have just upgraded to C++ XE8 and have updated the Steema packages. My application uses the information in a TTeePDFPage class object to form PDF output. When I compile the application, it does not find the class declaration. I have scanned through the installed files and cannot find any reference to the class.
I looked at your latest reference document (that was downloaded along with the install), and it shows that the TTeePDFPage is part of the TeePDFCanvas unit.
Could you please let me know what I am doing wrong?
Thanks

Hello,
I'm afraid this unit suffered lots of changes, to support stand-alone PDF Canvas, better speed with images, etc, etc.
The TTeePDFPage doesn't exist any more. Try using TPDFDocument instead.

Thanks for the information. I can really appreciate that things like this have to change.
I do have a request. Is there any documentation, examples, or anything available regarding the use of TPDFDocument? This class is not included in the latest reference material and I would like to know how it is used. Once I have this information, I think I can make the adjustments that I need.
Thanks for any help you might provide.

Hello,
Here it is a simple test example showing how to create a multi-page pdf document and how to add charts, images or how to use custom drawing function in each page:
Code: Select all
procedure TForm1.Button1Click(Sender: TObject);
const PDF='C:\tmp\test.pdf';
var c : TPDFCanvas;
b : TBitmap;
begin
c:=TPDFCanvas.Create;
try
c.Document.Orientation:=poLandscape;
c.StretchDraw(Rect(50,150,400,400),Image1.Picture.Graphic); // png
c.Draw(450,150,Image2.Picture.Graphic); // png
c.TextOut(50,50,'Hello');
c.Font.Size:=24;
c.TextOut(250,50,'World !');
TPDFExportFormat.Draw(c,Chart1,Rect(0,80,500,300));
b:=Chart1.TeeCreateBitmap;
try
c.Draw(350,650,b);
finally
b.Free;
end;
c.Brush.Style:=bsSolid;
c.Brush.Color:=clLime;
c.Pen.Style:=psSolid;
c.Pen.Color:=clBlue;
c.Pen.Width:=1;
c.Gradient.Visible:=True;
// c.Gradient.StartColor:=$8000FF00; // Alpha /CA Constant Opacity
c.Ellipse(420,10,520,110);
c.Gradient.Visible:=False;
c.Pen.Style:=psDot;
c.Rectangle(550,10,650,110);
c.Brush.Style:=bsClear;
c.Pen.Style:=psDash;
c.Pen.Width:=3;
c.TriangleWithZ(Point(660,110),Point(700,10),Point(740,110),0);
c.NewPage;
TPDFExportFormat.Draw(c,Chart1,Rect(0,80,500,300));
c.NewPage;
Chart1[0].FillSampleValues;
TPDFExportFormat.Draw(c,Chart1,Rect(0,80,500,300));
c.SaveToFile(PDF);
finally
c.Free;
end;
TeeGotoURL(0,PDF);
end;

The example was really helpful, thanks.
One more question. If I have an existing and already formatted TChart, how do I get it go to PDF? For example, I am displaying the chart to the user and he selects an option (which I give him) to export it to PDF, how can I control the output using TPDFExportFormat, TPDFCanvas, or some other class? In other words, how do I convert an existing chart to PDF?
Thanks for any help you can give.

Figured it out. Just need to get it formatted correctly as it is on the screen.
