<!-- ##### SECTION Title ##### -->
Photo database
<!-- ##### SECTION Short_Description ##### -->
Functions to create, read, write the photo database
<!-- ##### SECTION Long_Description ##### -->
<para>
These functions are for creating, reading, and writing the photo
database.
</para>
<para>
Overview of using the Photo database:
</para>
<para>
itdb_photodb_parse():
Read an existing PhotoDB.
</para>
<para>
itdb_photodb_create():
Create a new #Itdb_PhotoDB structure. The Photo Library Album is
(first album) is created automatically.
</para>
<para>
itdb_photodb_add_photo(), itdb_photodb_add_photo_from_data():
Add a photo to the PhotoDB (from file or from a chunk of
memory). It is automatically added to the Photo Library Album
(first album), which is created if it does not exist already.
</para>
<para>
itdb_photodb_photoalbum_create():
Create and add a new photoalbum.
</para>
<para>
itdb_photodb_photoalbum_add_photo():
Add a photo (#Itdb_Artwork) to an existing photoalbum.
</para>
<para>
itdb_photodb_photoalbum_remove():
Remove an existing photoalbum. Pictures can be kept in the
Photo Library or automatically removed as well.
</para>
<para>
itdb_photodb_remove_photo():
Remove a photo either from a photoalbum or completely from the database.
</para>
<para>
itdb_photodb_write():
Write out your PhotoDB.
</para>
<para>
itdb_photodb_free():
Free all memory taken by the PhotoDB.
</para>
<para>
itdb_photodb_photoalbum_by_name():
Find the first photoalbum with a given name or the Photo
Library Album if called with no name.
</para>
<para>
If you cannot add photos because your iPod is not recognized,
you may have to set the iPod model by calling
</para>
<para>
itdb_device_set_sysinfo (db->device, "ModelNumStr", model);
</para>
<para>
For example, "MA450" would stand for an 80 GB 6th generation iPod Video. See
<ulink type="http"
url="http://gtkpod.cvs.sourceforge.net/*checkout*/gtkpod/libgpod/src/itdb_device.c">itdb_device.c</ulink>
for a list of supported models.
</para>
<para>
This information will be written to the iPod when the PhotoDB is
saved (itdb_device_write_sysinfo() is called).
</para>
<para>
Have a look at the <ulink type="http"
url="http://gtkpod.cvs.sourceforge.net/*checkout*/gtkpod/libgpod/tests/test-photos.c">test-photos</ulink>
test program in the <ulink type="http"
url="http://gtkpod.cvs.sourceforge.net/gtkpod/libgpod/tests/">tests/</ulink>
directory of the libgpod source for an example of how to use the interface.
