Hello there. I have been investigating the EXIF tags that Windows XP can add to files, and have
successfully identified five extra tags and their mappings to the fields on the
File|Properties...|Summary tab in Explorer (both "simple" and "advanced" views).
XP ignores the standard UserComment field, alas, so I was forced to look into this.
(For those not using XP to manage their photos, Explorer allows you to view most EXIF data within
the File|Properties... dialog, and even add some EXIF fields as columns in Detail view)
Since I don't have CVS access, or even a PHP development environment that would allow me to do
the necessary changes myself, I am posting this here in hope that someone will add this to the
upcoming 4.2.0 build.
I suggest the following entries for the TagTable:
static const struct {
unsigned short Tag;
char *Desc;
} TagTable[] = {
{ 0x00FE, "NewSubFile"},
{ 0x00FF, "SubFile"},
..
{ 0x9c9b, "Title" }, // Win XP specific, Unicode
{ 0x9c9c, "Comments" }, // Win XP specific, Unicode
{ 0x9c9d, "Author" }, // Win XP specific, Unicode
{ 0x9c9e, "Keywords" }, // Win XP specific, Unicode
{ 0x9c9f, "Subject" }, // Win XP specific, Unicode, not to be confused with
SubjectDistance and SubjectLocation
Best regards,
