How to insert image in OpenOffice Document using Delphi

Question

I am using approach mentioned in accepted solution of How to Search and Replace in odt Open Office document? for search and replace text in odt document using Delphi

Answer 1

The following code was adapted from Listing 5.24 of Andrew Pitonyak's Macro Document.

ServiceManager := CreateOleObject('com.sun.star.ServiceManager');
Desktop := ServiceManager.createInstance('com.sun.star.frame.Desktop');
NoParams := VarArrayCreate([0, -1], varVariant);
Document := Desktop.loadComponentFromURL('private:factory/swriter', '_blank', 0, NoParams);
Txt := Document.getText;
TextCursor := Txt.createTextCursor;
{TextCursor.setString('Hello, World!');}
Graphic := Document.createInstance('com.sun.star.text.GraphicObject');
Graphic.GraphicURL := 'file:///C:/path/to/my_image.jpg';
Graphic.AnchorType := 1; {com.sun.star.text.TextContentAnchorType.AS_CHARACTER;}
Graphic.Width := 6000;
Graphic.Height := 8000;
Txt.insertTextContent(TextCursor, Graphic, False);

More information on using OpenOffice with Pascal is at https://www.freepascal.org/~michael/articles/openoffice1/openoffice.pdf.

EDIT:

This code inserts SHOW_CHART=123 and SHOW_CHART=456 as an example. Then it finds these strings and replaces them with the corresponding image.

Txt.insertString(TextCursor, 'SHOW_CHART=123' + #10, False);
Txt.insertString(TextCursor, 'SHOW_CHART=456' + #10, False);
SearchDescriptor := Document.createSearchDescriptor;
SearchDescriptor.setSearchString('SHOW_CHART=[0-9]+');
SearchDescriptor.SearchRegularExpression := True;
Found := Document.findFirst(SearchDescriptor);
While Not (VarIsNull(Found) or VarIsEmpty(Found) or VarIsType(Found,varUnknown)) do
begin
    IdNumber := copy(String(Found.getString), Length('SHOW_CHART=') + 1);
    Found.setString('');
    Graphic := Document.createInstance('com.sun.star.text.GraphicObject');
    If IdNumber = '123' Then
        Graphic.GraphicURL := 'file:///C:/path/to/my_image123.jpg'
    Else
        Graphic.GraphicURL := 'file:///C:/path/to/my_image456.jpg';
    Graphic.AnchorType := 1; {com.sun.star.text.TextContentAnchorType.AS_CHARACTER;}
    Graphic.Width := 6000;
    Graphic.Height := 8000;
    TextCursor.gotoRange(Found, False);
    Txt.insertTextContent(TextCursor, Graphic, False);
    Found := Document.findNext(Found.getEnd, SearchDescriptor);
end;

EDIT 2:

Embedding is explained in the next section of Andrew's document, Listing 5.26.

Bitmaps := Document.createInstance('com.sun.star.drawing.BitmapTable');
While...
    If IdNumber = '123' Then begin
        Bitmaps.insertByName('123Jpg', 'file:///C:/OurDocs/test_img123.jpg');
        Graphic.GraphicURL := Bitmaps.getByName('123Jpg');
    end Else begin
        Bitmaps.insertByName('456Jpg', 'file:///C:/OurDocs/test_img456.jpg');
        Graphic.GraphicURL := Bitmaps.getByName('456Jpg');
    end;
