################################################################################ <# .SYNOPSIS Removes image metadata files from image directories. .DESCRIPTION The Remove-ImageMetaData function removes companion JSON metadata files that are associated with images. It can selectively remove only keywords (description.json), people data (people.json), or objects data (objects.json), or remove all metadata files if no specific switch is provided. Language-specific metadata files can be removed by specifying the Language parameter, and all language variants can be removed using the AllLanguages switch. .PARAMETER ImageDirectory Specifies the directory containing images to process. Defaults to current directory if not specified. .PARAMETER Recurse When specified, searches for images in the specified directory and all subdirectories. .PARAMETER OnlyKeywords When specified, only removes the description.json files (keywords/descriptions). .PARAMETER OnlyPeople When specified, only removes the people.json files (face recognition data). .PARAMETER OnlyObjects When specified, only removes the objects.json files (object detection data). .PARAMETER Language Specifies the language for removing language-specific metadata files. When specified, removes both the default English description.json and the language-specific file. Defaults to English. .PARAMETER AllLanguages When specified, removes metadata files for all supported languages by iterating through all languages from Get-WebLanguageDictionary. .EXAMPLE Remove-ImageMetaData -ImageDirectory "C:\Photos" -Recurse Removes all metadata files for images in C:\Photos and all subdirectories. .EXAMPLE Remove-ImageMetaData -Recurse -OnlyKeywords Removes only description.json files from current directory and subdirectories. .EXAMPLE Remove-ImageMetaData -OnlyPeople -ImageDirectory ".\MyPhotos" Removes only people.json files from the MyPhotos directory. .EXAMPLE Remove-ImageMetaData -Language "Spanish" -OnlyKeywords -Recurse Removes both English and Spanish description files recursively. .EXAMPLE removeimagedata -AllLanguages -OnlyKeywords Uses alias to remove keyword files for all supported languages. .NOTES If none of the -OnlyKeywords, -OnlyPeople, or -OnlyObjects switches are specified, all three types of metadata files will be removed. When Language is specified, both the default English and language-specific files are removed. When AllLanguages is specified, metadata files for all supported languages are removed. #> function Remove-ImageMetaData { [CmdletBinding(SupportsShouldProcess = $true, ConfirmImpact = 'Medium')] [Alias("removeimagedata")] param( ####################################################################### [Parameter( Mandatory = $false, Position = 0, HelpMessage = "The image directory path." )] [string[]] $ImageDirectory, ####################################################################### [Parameter( Mandatory = $false, Position = 1, HelpMessage = "Recurse directories." )] [switch] $Recurse, ####################################################################### [Parameter( Mandatory = $false, HelpMessage = ("Only remove description.json files " + "(keywords/descriptions).") )] [switch] $OnlyKeywords, ####################################################################### [Parameter( Mandatory = $false, HelpMessage = ("Only remove people.json files " + "(face recognition data).") )] [switch] $OnlyPeople, ####################################################################### [Parameter( Mandatory = $false, HelpMessage = ("Only remove objects.json files " + "(object detection data).") )] [switch] $OnlyObjects, ####################################################################### [Parameter( Mandatory = $false, HelpMessage = ("The language for removing language-specific " + "metadata files.") )] [PSDefaultValue(Value = "English")] [ValidateSet( "Afrikaans", "Akan", "Albanian", "Amharic", "Arabic", "Armenian", "Azerbaijani", "Basque", "Belarusian", "Bemba", "Bengali", "Bihari", "Bosnian", "Breton", "Bulgarian", "Cambodian", "Catalan", "Cherokee", "Chichewa", "Chinese (Simplified)", "Chinese (Traditional)", "Corsican", "Croatian", "Czech", "Danish", "Dutch", "English", "Esperanto", "Estonian", "Ewe", "Faroese", "Filipino", "Finnish", "French", "Frisian", "Ga", "Galician", "Georgian", "German", "Greek", "Guarani", "Gujarati", "Haitian Creole", "Hausa", "Hawaiian", "Hebrew", "Hindi", "Hungarian", "Icelandic", "Igbo", "Indonesian", "Interlingua", "Irish", "Italian", "Japanese", "Javanese", "Kannada", "Kazakh", "Kinyarwanda", "Kirundi", "Kongo", "Korean", "Krio (Sierra Leone)", "Kurdish", "Kurdish (Soranî)", "Kyrgyz", "Laothian", "Latin", "Latvian", "Lingala", "Lithuanian", "Lozi", "Luganda", "Luo", "Macedonian", "Malagasy", "Malay", "Malayalam", "Maltese", "Maori", "Marathi", "Mauritian Creole", "Moldavian", "Mongolian", "Montenegrin", "Nepali", "Nigerian Pidgin", "Northern Sotho", "Norwegian", "Norwegian (Nynorsk)", "Occitan", "Oriya", "Oromo", "Pashto", "Persian", "Polish", "Portuguese (Brazil)", "Portuguese (Portugal)", "Punjabi", "Quechua", "Romanian", "Romansh", "Runyakitara", "Russian", "Scots Gaelic", "Serbian", "Serbo-Croatian", "Sesotho", "Setswana", "Seychellois Creole", "Shona", "Sindhi", "Sinhalese", "Slovak", "Slovenian", "Somali", "Spanish", "Spanish (Latin American)", "Sundanese", "Swahili", "Swedish", "Tajik", "Tamil", "Tatar", "Telugu", "Thai", "Tigrinya", "Tonga", "Tshiluba", "Tumbuka", "Turkish", "Turkmen", "Twi", "Uighur", "Ukrainian", "Urdu", "Uzbek", "Vietnamese", "Welsh", "Wolof", "Xhosa", "Yiddish", "Yoruba", "Zulu")] [string] $Language = "English", ####################################################################### [Parameter( Mandatory = $false, HelpMessage = ("Remove metadata files for all supported " + "languages.") )] [switch] $AllLanguages ####################################################################### ) begin { #
