Feature Request: Restore -Format option in Get-Clipboard

[tats-u]

Summary of the new feature/enhancement

We used to be able to save images in the clipboard as files by following in Windows Powershell 5:

(gcb -format image).save("foo.png")

As you know, Get-Clipboard went somewhere in PowerShell Core 6 but came back in 7. The remaining problem is that only text is supported and we can't fetch images (and audio). Windows lacks the feature to save an image in the clipboard as a file. I don't want to run Paint 3D or something, paste one, and save it. (I found we can paste a medium in clipboard to Explorer)
PowerShell 7 is said to be compatible with 5, but this absence gives me an opportunity to run the legacy PowerShell 5.

Proposed technical implementation details (optional)

If I remember right it was a design conclusion to have consistent behavior over all supported systems but we do not consider such scenario.

I would like to add that a method capable of outputting the image into different size chunks, such as the following, would be a welcomed addition.

$MediaFileInfo = Get-ChildItem $Path
$BufferSize = 900000
$Buffer = [Byte[]]::new($BufferSize)
$Reader = [System.IO.File]::OpenRead($MediaFileInfo.FullName)
$Media = [ArrayList]::new()
do {
    $BytesRead = $Reader.Read($Buffer, 0 , $BufferSize)
    $null = $Media.Add([Convert]::ToBase64String($Buffer, 0, $BytesRead))
} while ($BytesRead -eq $BufferSize)
$Reader.Dispose()

Perhaps something like ConvertToBase64() with a default or configurable buffer size?

Thank you,
Dave

Still no answers.
Do we have to use the WinForms directly or a 3rd-party CLI tool?

Not fixed
