Exiv2

JPEG parser should be able to read/write standalone JPEG APP1 segments, leave the code common in JpegImage.
An App1Image class derived from JpegBase will deal with the format recognition.

Additional information:

From an email exchange with Gilles Caulier:

This seems to be a complete JPEG APP1 Exif segment. To support this in Exiv2,
I'll need to tweak the JPEG parser a bit to also accept such a segment alone,
but will have to be very careful to avoid side effects.
A quick hack is faster: The TIFF header starts 10 bytes into the file, so just
add 10 from the beginning of the data buffer and use ExifData::load...

// Read the file into a memory buffer
    long len = io.size();
    DataBuf buf(len);
    io.read(buf.pData_, buf.size_);
    if (io.error() || io.eof()) throw Error(14);

ExifData exifData;
    int rc = exifData.load(buf.pData_ + 10, buf.size_ - 10);

-ahu.

Andreas,

Here we are a bin raw exif file extrcated from my Minolta Dynax 5D camera
using gphoto2 interface (via digikam camera gui)

This file cannot be parsed by Exiv2. I don't know why...

But, this file can be parsed using libexif (via old implementation of
digikam).

Can you give me your viewpoint ? This problem can be fixed easily into
Exiv2 core ?

Thanks in advance
