LR 4 changes to photo:get*Metadata()

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:

album = "This is Album",

altTapeName = "This is alternate tape name",

audioSampleRate = "44100",

cameraAngle = "Birds Eye Shot",

cameraModel = "This is camera model",

cameraMove = "Truck Left",

client = "This is client",

comment = "This is comment",

composer = "This is composer",

description = "Hello world"}}

dimensions = {--table: 5

director = "This is director",

directorPhotography = "This is directory of photography",

dm_artist = "This is  artist",

dm_scene = "This is  scene",

durationInSeconds = 64.066666666667,

durationRatio = {--table: 6

    numerator = 961,

    denominator = 15},

engineer = "This is engineer",

genre = "This is Genre",

good = "True",

instrument = "This is instrument",

logComment = "This is log comment",

projectName = "This is project name",

releaseDate = "This is release date",

shotDate = "This is shot date",

shotDay = "This is day of shoot",

shotLocation = "This is shot location",

shotName = "This is shot name",

speakerPlacement = "This is speaker placement",

tapeName = "This is tape name",

trimmedDurationInSeconds = 64.066666666667,

trimmedDurationRatio = {--table: 4

    numerator = 961,

    denominator = 15},

videoPixelAspectRatio = 1,

photo:getDevelopSettings()

ProcessVersion has these values:

"5.0" = PV 2003

"5.7" = PV 2010

"6.6" = PV 2012 beta

"6.7" = PV 2012

These fields represent the new settings of PV 2012:

AutoLateralCA = 0,

Blacks2012 = 0,

Clarity2012 = 0,

Contrast2012 = 0,

DefringeGreenAmount = 0,

DefringeGreenHueHi = 60,

DefringeGreenHueLo = 40,

DefringePurpleAmount = 0}

DefringePurpleHueHi = 70,

DefringePurpleHudeLo = 30,

Exposure2012 = 0,

Highlights2012 = 0,

Shadows2012 = 0,

ToneCurveName2012 = "Linear",

ToneCurvePV2012 = {--table: 6

ToneCurvePV2012Blue = {--table: 5

ToneCurvePV2012Green = {--table: 3

ToneCurvePV2012Red = {--table: 2

Whites2012 = 0,

Video fields:

TrimEnd = {--table: 7
    denominator = 15,
    numerator = 961},
TrimStart = {--table: 6
    denominator = 1,
    numerator = 0},

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.

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