Deployment Method:


This applies to both open source and commercial editions of Chocolatey.

1. Enter Your Internal Repository Url

(this should look similar to https://community.chocolatey.org/api/v2/)

2. Setup Your Environment

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

2. Get the package into your environment

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Copy Your Script

choco upgrade pngquant -y --source="'INTERNAL REPO URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

choco upgrade pngquant -y --source="'INTERNAL REPO URL'" 

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0

Exit $exitCode

Package Approved

This package was approved as a trusted package on 19 Dec 2023.



pngquant is a command-line conversion utility and library to quantize (lossy compression) and
dither truecolor PNG images, especially those with a full alpha channel, down to 8-bit (or smaller)
RGBA-palette PNGs. Such images are usually two to four times smaller than the full 32-bit versions, and
partial transparency is preserved quite nicely. This makes pngquant especially useful both for Web sites
and for PlayStation 2 development, where one of the texture formats is RGBA-palette-based (though not
PNG-compressed). This is the same technique used for many of the images on the Miscellaneous Transparent
PNGs page (http://www.libpng.org/pub/png/pngs-img.html), and the results are often indistinguishable from
the original, truecolor PNG images.

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).
