Exiv2

Great, thank you !
I have tested your patch. The missing tags are now well visible, but are not correctly presented:
Here is an sample of 'exiv2 -pa <picture>' output:

I have tried to modify the patch file: I have changed 'undefined' by 'asciiString' (for instance line 451 of panasonicmn.cpp, for the Country tag). But I'm not familiar with it at all -> this was not very successful ...

One remark: why is there 2 lines for the tag 'Baby Age' (0x0033 and 0x8010 tags) ?

Thanks in advance

Thank you, it's better !! But it can still better. Here are a few remarks:

1) Exif.Panasonic.InternalSerialNumber -> should also use your printPanasonicText function (panasonicmn.cpp line 405)

2) Exif.Panasonic.ProgramISO displays '65534' instead of 'Intellent ISO' (according to exiftool) (see example on picture [1])

3) if not set, Exif.Panasonic.TravelDay displays '65535' instead of 'not set' [1] ; otherwise it displays the correct number of days

4) the Face Detection information is not correctly displayed. I have seen 3 exif tags:
4.1) Exif.Panasonic.FacesDetected -> number of detected faces: OK (there are 2 in the picture given as example in [1])
4.2) Exif.Panasonic.FaceDetInfo -> it is a list of the position of the faces on the picture
4.3) Exif.Panasonic.FaceRecInfo -> it is a list of information concerning the recognized persons: each recognized person has his Age + Name + position on the picture
Points 4.2 and 4.3 are not shown with exiv2.
For information, exiftool output for [1] is:

exiftool Desktop/TEST_FACE_DETECTION.jpg | grep -i face
File Name                       : TEST_FACE_DETECTION.jpg
AF Area Mode                    : Face Detect

Num Face Positions              : 2

Recognized Face 1 Name          : POUTINE

Recognized Face 1 Age           : 0009:00:05 00:00:00     '9 year old, 0 month, 5 days: it is correct since I have not put the correct age in my camera ;-)
Recognized Face 2 Name          : OBAMA
Recognized Face 2 Position      : 251 103 24 24
Recognized Face 2 Age           : 0015:04:00 00:00:00

5) Exif.Panasonic.TimeSincePowerOn not correctly diplayed (shows the time in milliseconds instead of a readable format in hour/minute/second). Just to try, I have add the following function 'printTimeSincePowerOn' in panasonicmn.cpp following your 'printPanasonicText' function (+ added it on line 409 + in panasonicmn_int.hpp file).
And it works (but needs amelioration to have a better format). For [1], it outputs "0:4:31.48" (instead of "00:04:31.48")

    std::ostream& PanasonicMakerNote::printTimeSincePowerOn(std::ostream& os,
                                                  const Value& value,
                                                  const ExifData*)
    {
    //if(value.size()>0 ) //not needed ?
        //{
        long time=value.toLong();
        //TODO: add something like  <<std::setw(2)<<std::setfill('0') to format the output
        os << time/360000<<":"<<(time%360000)/6000<<":"<<(time%6000)/100<<"."<<time%100;
        return os;
        //}
        //else
        //{
        //    return os << value;
        //};
    } // PanasonicMakerNote::printTimeSincePowerOn

[1] > see example on the picture http://nicofo.tuxfamily.org/tmp/TEST_FACE_DETECTION.jpg where I have added the face detection of Poutine and Obama ;)

Excellent, thanks again, it works as expected, I have no other remark except concerning the "baby age2": you changed the second 'BabyAge' into 'BabyAge2': maybe you should also change the description i.e. 'Baby (or pet) age' -> 'Baby (or pet) age2'. Rem: exiftool has only one tag 'Baby age'.

For the Face detection information, I can eventually fill a new bug report so that this one can be closed. I don't know if it is useful ??? (eventually to have your patch included in the next release of exiv2 even if Face Detection is not fixed)

Thank you.
Concerning the tag 0x003d "Advanced Scene Type" you just added, you just use the 'printValue' method to display it. As a result a code (1 to 14) is displayed. Here are the information that should be printed (instead of the number):

1    normal        Normal
2    outdoor        Outdoor/Illuminations/Flower/HDR Art
3    indoor        Indoor/Architecture/Objects/HDR B&W
4    creative    Creative
5    auto        Auto
7    expressive    Expressive
8    retro        Retro
9    pure        Pure
10    elegant        Elegant
12    monochrome    Monochrome
13    dynamic        Dynamic Art
14    silhouette    Silhouette

Rem: I have updated your patch to swap baby age 1 and 2 (according to the same pdf and other programs) and add a number (so "Text stamp" becomes "Text stamp 1" etc.)

According to http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/Panasonic.html the tag 0x003d can contain more values and should be seen with tag 0x8001 SceneMode (see composite tag AdvancedSceneMode). Your implementation covers only a small subset of the values. So I don't agree with your changes.

Yes, I had seen your page too, but what I read there did not correspond to my pictures metadata (or all the combinations of 003d and 8001 are not listed).
Unless I don't interpret it correctly.

For instance, for a picture made using full automatic control (and where the camera detects a night scene), I have:
- Advanced Scene Type = 5
- Scene Mode = "Handheld Night Shot" (55)

For another picture made using the scene mode 'night scene', I have:
- Advanced Scene Type = 1
- Scene Mode = "Handheld Night Shot" (55)

-> How should I understand that with your table ?

or all the combinations of 003d and 8001 are not listed

That may be. So if you found other combination report them also to Phil Harvey from ExifTool.

Just one example:
- Advanced Scene Type = 3
can mean
- Indoor Portrait
- Architecture
- Indoor Sports
- Object
- HDR B&W
- High Key
- Color Select
- Old Day
depending on the value of SceneMode. (At least these are the already decoded combinations. Not all combinations are used by all cameras. The possible combination depends on the actual camera model.)
So which value should be printed for tag AdvancedSceneType? All like in your example? This would not be helpful.

Hi,
I don't agree with the last version of the patch.
The tag 0x6d is used for the "City" tag. All (previous) models are using this nomenclature.
Only for the newer TZ40 the meaning changed and the city tag moved to 0x80 and tag 0x6d is used for the county.
So this version would not so fine for all (older) cameras.

So maybe City for 0x6d and City2 for 0x80 is more appreciate (and also used by exiftool).
