Adobe Community: Message List - LR 4 changes to photo:get*Metadata()

Re: LR 4 changes to photo:get*Metadata()

The photo:getRawMetadata() field "description" listed above for video files is a bug -- it shouldn't be present. See:

yep I know - its like saying that LR3 almost supported pick status?

BTW LR4 does have some weird behaviour if you try to set CropWidth/CropHeight, the picture is then shown in wrong aspect ratio. I had to filter out those from my XMP preset ripper plugin.

Maybe we get API cropping for Lightroom 5.0?

Almost all the mechanism is already present: photo:getDevelopSettings() returns the a photo's current crop settings, and LrApplication.addDevelopPresetForPlugin() lets a plugin create new presets. The only problem is that develop presets don't allow crop settings.

Just tested:

photo:setRawMetadata("pickStatus", -1) -- reject

photo:setRawMetadata("pickStatus", 0) -- no flag

photo:setRawMetadata("pickStatus", 1) -- pick

These seem to be working as expected with 4.1 RC2. Maybe we get API cropping for Lightroom 5.0?

I'm assuming Adobe wanted to get the new defringing parameters in there before releasing the new SDK...

Thx John,

Automagically, and leisurely.

@Lr4.0, Lightroom would not convert all entries from 6.6 to 6.7 - only when one goes to view or make an adjustment. I'm really not sure what-all prompts it, I just noticed they've been sorta disappearing over time...

So, YES - any robust code must be able to recognize 6.6. I've gotten away with assuming it's identical to 6.7, but obviously there could be some differences or there wouldn't have been a different number in the first place.

I mean, I discovered it via error messages in my code that was originally not recognizing it.

I wish Adobe would have just converted all entries when reading a beta catalog, so there would not be this issue, but alas, that is not the case.

Here's an updated list that includes video fields and Whites2012:

photo:getFormattedMetadata()

gpsAltitude is now in feet rather than meters:

"2500.0 ft" rather than "762.00 m"

I don't know if this is localized to each country.

Video fields:

duration = "01:04.0",

frameRate = "30.000 fps",

photo:getRawMetadata()

The representation of photos not in a stack has changed. In LR 3.6 it is:

countStackInFolderMembers = 1,

stackInFolderMembers = {--table: 3

[1] = LrPhoto( id "14000" )},

stackPositionInFolder = 1,

topOfStackInFolderContainingPhoto = LrPhoto( id "14000" ),

In LR 4.1 RC2 it is:

countStackInFolderMembers = 0,

stackInFolderMembers = {},

stackPositionInFolder = 1,

LR 4's representation is inconsistent but more memory-efficient.

At last, there's pickStatus!

0 = unflagged

1 = flagged

-1 = rejected

I haven't tested whether pickStatus can be changed via photo:setRawMetadata().

There's a new field root_uiid:

root_uuid = "545E7456-C7D3-40F1-8E65-6F4225D057A4",

Video fields:

ProcessVersion has these values:

"5.0" = PV 2003

"5.7" = PV 2010

Btw, how does a photo actually get updated from 6.6 to 6.7? I'm puzzled if I would need to handle 6.6 in my code at all (I'm not currently doing it, I know my UI doesnt work properly with 6.6 version)

Re: LR 4 changes to photo:get*Metadata()

forums_noreply@adobe.com — Sat, 28 Apr 2012 05:56:44 GMT

Thanks John!

Also, ProcessVersion = "6.6" may be returned for PV2012/beta-not-yet-converted to "6.7".

LR 4 changes to photo:get*Metadata()

Since we have no idea when the LR 4 SDK documentation might arrive, I started reverse-engineering changes to photo:getFormattedMetadata() and photo:getRawMetadata(). Here are the differences I've observed between LR 3.6 and LR 4.1 RC2:

photo:getFormattedMetadata()

gpsAltitude is now in feet rather than meters:

"2500.0 ft" rather than "762.00 m"

I don't know if this is localized to each country.
