FR5 frxExportPDF.pas bug - fixed!

Chewmatca

Kept getting AV errors with PDF exports with around 8500 outlines. My exports were dieing at around page 350 Then a big EOutOfMemory error.

Work around was to turn off "Outline" on report export.

Fix was to remove the recursive iterations of TfrxPDFOutlineNode.Destroy, for each item if there was a next it would go deeper in recursion, a great way to kill your app...

I can now run 1700+ page exports with Outline on.

Also goes for the Outline exporting routine.

Major functions added to TfrxPDFExport.Finish:

Procedure RecursiveOutline(OutlineNode:TfrxPDFOutlineNode);
var
TempOutlineTreeNode : TfrxPDFOutlineNode;
OutlineCount : Integer;

begin

if OutlineNode <> nil then
begin

TempOutlineTreeNode := OutlineNode.First;

for OutlineCount := 0 to OutlineNode.Count -1 do
begin

if TempOutlineTreeNode <> nil then
begin
WriteOutline(TempOutlineTreeNode);

RecursiveOutline(TempOutlineTreeNode);

end;
TempOutlineTreeNode := TempOutlineTreeNode.Next;
end;
end;

end;

Procedure RecursiveFreeOutline(OutlineNode:TfrxPDFOutlineNode);
var
TempOutlineTreeNode : TfrxPDFOutlineNode;
PrevOutlineNode : TfrxPDFOutlineNode;
OutlineCount : Integer;

begin

if OutlineNode <> nil then
begin


TempOutlineTreeNode := OutlineNode.Last;

for OutlineCount := 0 to OutlineNode.Count -1 do
begin

if TempOutlineTreeNode <> nil then
begin
PrevOutlineNode := TempOutlineTreeNode.Prev;

RecursiveFreeOutline(TempOutlineTreeNode);

TempOutlineTreeNode.Free;
TempOutlineTreeNode := nil;
end;

TempOutlineTreeNode := PrevOutlineNode;
end;

end;

end;

May help someone who has to use the built in PDF engine.
