Translate to any language using PowerShell

📅 31. Mai 2024 · Software · ⏱️ 3 min

Google's online translation service is an easy way to translate text into any language.
For example:

[string]$text = "The picture."
online-translate "de" $text

The returned translation is "Das Bild."

Or:

[string]$text = "The picture search is finished. %1!d! pictures have been scanned and %2!d! duplicate pictures were found.
Would you like to see the list with the duplicate picture names?"
online-translate "de" $text

The returned translation is "Die Bildsuche ist beendet. %1!d! Bilder wurden gescannt und %2!d! Es wurden doppelte Bilder gefunden. Möchten Sie die Liste mit den doppelten Bildnamen sehen?"

Please note the unmodified placeholders (Ensure to use the REST API setting 'client=gtx').

This is all done with a PowerShell script using the public Google REST API:

<#
.DESCRIPTION
    Translate any text for a language using the google online translation service.
#>
function online-translate([string]$language, [string]$text) {

    # Escape newlines.
    $text = $text.Replace("`n", '
')

    # The google rest API.
    [string]$uri = "https://translate.googleapis.com/translate_a/single?client=gtx&tl=$language&q=$text&sl=auto&dt=t"
    [string]$response = (Invoke-WebRequest -Uri $uri -Method Get).Content

    # Combine the segments of the response to a single string.
    # Regex is rather simple: Use the start pattern '[[["', or the segment pattern ']]]],["'
    # to capture the sentences in the text group.
    $m = ([regex]'(?:(?:^\[\[\[)|(?:\]\]\]\],\[))"(?<text>.*?)",".*?",null').Matches($response)
    [string]$translation = ($m | % { $_.groups['text'].Value }) -join ""

    # Adjust the translated text.
    $translation.Replace('\"', '"').Replace('\
', "`n").Replace('\
', "`r").Replace('[TAB]', "`t").Replace('\u003c', '<').Replace('\u003e', ">").Replace('\u003d', "=").Replace('\\\\', "\\")
}

The REST API response is more complex than the call itself, but with a simple regex this problem is easily solved in the function.
The starting pattern '[[["' or the segment pattern ']]]],["' is used to capture the sentences in the text group.
The number of segments depends on the text input. For example:

Small text return a single segment response:

[[["Das Bild.","Das Bild.",null,null,5]],null,"de",null,null,null,1,[],[["de"],null,[1],["de"]]]

Larger text return a multi segment response:

[[["Die Bildsuche ist beendet. ","The picture search is finished.",null,null,3,null,null,[[]],[[["84d48e73ebfa38d4d681515b81e0b72a","en_de_2023q1.md"]]]],["%1!d! ","%1!d!",null,null,3,null,null,[[]],[[["84d48e73ebfa38d4d681515b81e0b72a","en_de_2023q1.md"]]]],["Bilder wurden gescannt und %2!d! ","pictures have been scanned and %2!d!",null,null,3,null,null,[[]],[[["84d48e73ebfa38d4d681515b81e0b72a","en_de_2023q1.md"]]]],["Es wurden doppelte Bilder gefunden.\
Möchten Sie die Liste mit den doppelten Bildnamen sehen?","duplicate pictures were found.\
Would you like to see the list with the duplicate picture names?",null,null,3,null,null,[[]],[[["84d48e73ebfa38d4d681515b81e0b72a","en_de_2023q1.md"]]]]],null,"en",null,null,null,1,[],[["en"],null,[1],["en"]]]

Laowa 4mm f/2.8 Fisheye Lens

📅 9. Mai 2024 · Panorama · ⏱️ 2 min

The Laowa 4mm f/2.8 is a manual focus Circular Fisheye lens for APS-C cameras.

Best setting for 360°×180° Panoramas is at the beginning of the infinity mark and f/5.6. This puts everything from near to infinity in focus:

The 4mm Circular Fisheye lens allows you to capture stunning and unique shots:

And a 360°×180° panorama with just two pictures:

1/1000s f/5.6 ISO 100/21°

Interactive Panorama Laowa 4mm

On a sunny day, position yourself so that your shadow falls within the area of overlap (your shadow is perpendicular to the direction you are looking):

The overlap with the lens's 210° field of view at the seam is large enough to cover the shadow. Even for a nodal point adapter with a small footprint.
This is not possible with a 180° Fisheye.

With the lens at a height of 1.6m, the 30° overlap is 1.6m*2*tan(15°)=0.85m (2ft 9").

Shadow covered:

It is common for fisheye lenses to have decreased image quality toward the edges, but not really an issue if it is only used for web/social media. The ordinary Tiktok brain does not recognize this deficiency anyway.
The two images were taken without a tripod, so the stitch does not result in everything perfectly vertical and also has some minor misalignments. And with only two images, there is not much to vary. A nodal point adapter is recommended.
