通过 PowerShell 获取已卸载 Windows fonts 的详细信息

Question

I'm using PowerShell and ImageMagick to create customized images of my font collection to determine which fonts I want to install into the system. I'd like to have the image include some font information, but I am having a difficult time extracting that information. I found some useful code at https://powershell.org/forums/topic/listing-font-details/#post-78006 , but I found that information is only accessible within the system's font directory. My collection exists outside of %SystemRoot%\Fonts .

I'd like to access things like

• font name (Aparajita)
• font style (bold, normal, italic)
• font type (Raster, OpenType/TrueType)

etc.

Is this possible?

Answer 1

Using the Shell.Application COM object to get details of files is not limited to the %SystemRoot%\Fonts folder.

If you have a folder on disk where you keep your collection of fonts, you could use the below code to get information for each of the font files:

function Get-FontInfo {
    [CmdletBinding()]
    [OutputType([Psobject])]
    Param (
        [Parameter(Mandatory=$true, ValueFromPipeline=$true)] 
        [string]$SourceFolder,
        [switch]$Recurse
    )
    # using a lookup hashtable to avoid localized field names
    $fontProperties = [ordered]@{
        0   = 'Name'
        1   = 'Size'
        2   = 'Type'
        20  = 'Author'
        21  = 'Title'
        25  = 'Copyright'
        33  = 'Company'
        34  = 'Description'
        164 = 'Extension'
        165 = 'FileName'
        166 = 'Version'
        194 = 'Path'
        196 = 'FileType'
        310 = 'Trademark'
    }
    $shell  = New-Object -ComObject "Shell.Application"
    $objDir = $shell.NameSpace($SourceFolder)
    $files  = Get-ChildItem -Path $SourceFolder -Filter '*.*' -File -Recurse:$Recurse

    foreach($file in $files) {
        $objFile   = $objDir.ParseName($file.Name)
        $mediaFile = $objDir.Items()
        $output    = [ordered]@{}
        $fontProperties.GetEnumerator() | ForEach-Object {
            $name  = $objDir.GetDetailsOf($mediaFile, $_.Name)
            if (![string]::IsNullOrWhiteSpace($name)) { 
                $output[$_.Value] = $objDir.GetDetailsOf($objFile, $_.Name)
            }
        }
        [PsCustomObject]$output
    }

    $null = [System.Runtime.Interopservices.Marshal]::ReleaseComObject($objFile)
    $null = [System.Runtime.Interopservices.Marshal]::ReleaseComObject($objDir)
    $null = [System.Runtime.Interopservices.Marshal]::ReleaseComObject($shell)
    [System.GC]::Collect()
    [System.GC]::WaitForPendingFinalizers()
}

Get-FontInfo -SourceFolder 'D:\Test'  # the path of the font folder

If you have subfolders inside the source folder, also add the -Recurse switch.

Output something like:

Name        : aparaj.ttf
Size        : 194 kB
Type        : TrueType-lettertypebestand
Author      : 
Title       : Aparajita
Copyright   : Copyright (c) 2011, Modular Infotech, Pune, INDIA. - Licenced to Microsoft
Company     : 
Description : This font is primarily meant for use in displaying Hindi text in documents. It is an OpenType font, based on Unicode. 
Extension   : .ttf
FileName    : aparaj.ttf
Version     : 6.00
Path        : D:\Test\aparaj.ttf
FileType    : TrueType-lettertypebestand

Answer 2

After reviewing Theo's answer, and doing some code modification, I made the discovery that there are different extended attributes depending on if the font is installed or not. The top section of the following output is when the font is installed, versus the bottom section when it is not installed. In short, if I want to embed the 'Font Style' and 'Designed For' into the image Im generating, I need to install the font first.
