)
typedef struct PA_Picture
{
long fSize;
PA_Handle fHandle;
} PA_Picture;
/*
a PA_Picture can contains various representation of the same picture
in different formats to ensure the best display depending on which
platform the picture is displayed,
or if the picture is displayed on screen or on printer
you can iterate throw those representations by incrementing index until
an error is returned the returned string will give informations about
the format of the picture (JPEG, PNG...) if you pass a NULL handle,
you are just collecting informations about the picture by examining
the returned string when you pass a valid handle allocated by PA_NewHandle,
the handle will be filled by the specific data of the picture,
in the indexed picture format.
