How do I read all the keywords? Assume keywords in photoshopped file are
New Mexico; Canyon; Nature
When I do the following I only retrieve the first keyword into the string variable temp (New Mexico) and can't see the others.
Idx:=ImageEnIO1.Params.IPTC_Info.IndexOf(2,25);
temp:=ImageEnIO1.Params.IPTC_Info.StringItem[idx];
Thanks |

Also, there are some useful IPTC functions in:
iexIPTCRoutines.pas

Also there is a demo at ...ImageEn\Samples\InputOutput\IPTC

OK, thanks. I'd already figured out that what I needed is the following code snippet. Thanks for your advice, it allowed me to figure this out.
with IPTC_Info do
begin
idx := indexof(2, 25);
if idx >= 0 then
begin
temp := StringItem[idx];
for idx := idx + 1 to Count - 1 do
if (RecordNumber[idx] = 2) and (DataSet[idx] = 25) then
temp := temp+';'+StringItem[idx];
end;
end;

What is the variable "iptc" in
for i := 0 to high(iptc) do

You have to loop through the IPTC_Info:
// GetIPTCInfo
procedure TForm1.GetIPTCInfo(const Filename: string);
var
i, j, k, l: integer;
ListItem: TListItem;
begin
ListView1.Clear;
for i := 0 to high(iptc) do
begin
ListItem := ListView1.Items.Add;
ListItem.Caption := iptc[i].s;
end;
// read IPTC
for j := 0 to high(iptc) do
with ImageEnView1.IO.Params.IPTC_Info do
begin
k := IndexOf(iptc[j].r, iptc[j].d);
if k >= 0 then
begin
// tag found
ListView1.Items.Item[j].SubItems.Add(StringItem[k]);
// look for other fields with the same recordnumber and dataset
for l := k + 1 to Count - 1 do
if (RecordNumber[l] = iptc[I].r) and (DataSet[l] = iptc[i].d) then
ListView1.Items.Item[j].SubItems.Add(StringItem[l]);
end;
end;
end;
