FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
To use Composer is sometimes complicated. Especially for beginners.
Composer needs much resources. Sometimes they are not available on a simple webspace.
If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Please rate this library. Is it a good library?

Informations about the package upscale-calculator

Upscale Calculator

Small, dependency-free PHP helpers for the math around image upscaling:

scaled pixel dimensions, megapixels and aspect ratio
the smallest upscale factor (2x, 4x, 6x, or your own list) that reaches a target size
pixel requirements and maximum print size at a given DPI

The library only does arithmetic. It makes no network requests and does not read or write image files.

Install

Requires PHP 8.1 or newer.

Usage

factorFor() and factorForPrint() return 1.0 when the image is already large enough and null when none of the supported factors is enough.

Pass your own factors if your upscaler supports a different set:

Testing

About

Maintained by Tancky AI. The default factors match the 2x, 4x and 6x options of the Tancky AI Image Upscaler, where the same calculations decide which option an image needs.
