>   virtual BOOL LoadBrushDirect::OnLoadDocument(Document* pKernelDoc)

    Author:     Diccon_Yamanaka (Xara Group Ltd) <camelotdev@xara.com>
    Created:    3/2/2000
    Inputs:     pKernelDoc = a pointer to the loaded kernel document
    Returns     TRUE if the document was processed correctly
                FALSE if not.
    Purpose:    We need to replace indexed brush colours by local colours - since the linked
                indexed colours get deleted (this especially effects fill ramps!).

                NOTE:  identical to that in void PrintMarksMan::ConvertAllDocColours(Document* pDoc)

*****************************************************************************************/

BOOL LoadBrushDirect::OnLoadDocument(Document* pDoc)
{
    ERROR3IF(pDoc==NULL,"No doc pointer during PrintMarksMan::ConvertAllDocColours!");

    Node *CurNode = Node::DocFindFirstDepthFirst(pDoc);
    Node *NextNode;

    while (CurNode !=NULL)
    {
        // We may be about to chop this node out of the tree, so get the next node now
        NextNode = CurNode->DocFindNextDepthFirst();

        // Use to scan the colour fields of the attribute.
        UINT32 Context = 0;
        DocColour *pColour;

        if (CurNode->IsAnAttribute())
        {
            NodeAttribute *pNodeAttr = (NodeAttribute *) CurNode;

            // Get the next colour field from the attribute
            pColour = pNodeAttr->EnumerateColourFields(Context++);

            while (pColour != NULL)
            {
                // For each colour field, make sure the colour is a local DocColour so that
                // the sub-tree is entirely stand-alone
                if (pColour->FindParentIndexedColour() != NULL)
                {
                    ColourGeneric ColDef;
                    ColourContext *cc = ColourManager::GetColourContext(pColour->GetColourModel());
                    ERROR3IF(cc == NULL, "Can't find colour context?!");

                    // Get the IndexedColour definition as a standalone colour definition
                    cc->ConvertColour(pColour->FindParentIndexedColour(), &ColDef);

                    // Make the DocColour into a simple standalone "lookalike" of the parent colour
                    *pColour = DocColour(pColour->GetColourModel(), &ColDef);
                }

                pColour = pNodeAttr->EnumerateColourFields(Context++);
            }
        }
        CurNode = NextNode;
    }

    // All is well we hope.
    return TRUE;
}
