How to set with offline image in Chocolatey Packages for internal packages?

Question

I have developed a few internal Chocolatey Packages and the internal repository has no access to Internet. I'd like to have the icon of the packages I have developed to be included in the package itself. Is this possible in Chocolatey?

Answer 1

There is nothing currently in Chocolatey that would allow for the embedding on icons into the package. This would also require that the repository that you are using supported extracting the icon from within the package for display. In the interim, my suggestion would be to host the icons internally on your own website, and update the nupsec files with the internal location for the icons.

Answer 2

No idea if this is the sort of thing you need as I don't use Chocolatey but here's how to use Base64 so that you can embed images in your scripts...

Get the image data:

# Path to image file
$PathToSourceImage = 'c:\temp\image.jpg'
$PathToExe = 'c:\temp\example.exe'

# Convert image to Base64 and copy to clipboard - or there's several websites where you can do this.
[convert]::ToBase64String((get-content $PathToSourceImage -encoding byte)) | Clip

You can also extract from icon or executable:

$Icon = [System.Drawing.Icon]::ExtractAssociatedIcon($PathtoExe)
$MemoryStream = New-Object System.IO.MemoryStream
$Icon.save($MemoryStream)
$Bytes = $MemoryStream.ToArray()   
$MemoryStream.Flush() 
$MemoryStream.Dispose()
[convert]::ToBase64String($Bytes) | Clip

Now use the image data in your script

# Paste the Base64 data here and assign to a variable.....
$IconBase64 = 'AAABAAEAICAQKAAAAADoAgAAFgAAACgAAAAgAAAAQAAAAAEABAAAAAAAgAIAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACAAACAAAAAgIAAgAAAAIAAgACAgAAAgICAAMDAwAAA

# Convert back to PS icon object
$iconBytes = [Convert]::FromBase64String($iconBase64)
$stream = New-Object IO.MemoryStream($iconBytes, 0, $iconBytes.Length)
$stream.Write($iconBytes, 0, $iconBytes.Length);
$MyIcon = [System.Drawing.Icon]::FromHandle((New-Object System.Drawing.Bitmap -Argument $stream).GetHIcon())

# You can also convert to bitmap etc for images
$Bytes = [Convert]::FromBase64String($iconBase64)
$stream = New-Object IO.MemoryStream($Bytes, 0, $Bytes.Length)
$stream.Write($Bytes, 0, $Bytes.Length);
$MyImg = New-Object System.Drawing.Bitmap -Argument $stream


# Example using Forms

Add-Type -AssemblyName System.Windows.Forms

$form = New-Object System.Windows.Forms.Form
$form.Font = $DefaultFont
$form.Text = "Test"
$form.Size = '400,400'
$form.StartPosition = 'CenterScreen'
$form.FormBorderStyle = 'FixedSingle'
#
# Using the icon
$form.Icon = $MyIcon


$DASImage = New-Object System.Windows.Forms.PictureBox
$DASImage.Width = $MyImg.Width
$DASImage.Height = $MyImg.Height
$DASImage.Location = '10,10'
$DASImage.Image = $MyImg

$form.Controls.Add($DASImage)

# Show form
$form.ShowDialog() | Out-Null
$form.Dispose()

Ensure your icon images are a suitable size etc
