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.

Informations about the package slika

Slika - simple image handling for PHP

This is a library that covers only the bare basics you need when handling images:

It can use either PHP's libGD or a locally installed ImageMagick binary.

Installation

Use composer

composer require splitbrain/slika

Usage

Simply get an Adapter from the Slika factory, run some operations on it and call save.

Operations can be chained together. Consider the chain to be one command. Do not reuse the adapter returned by run(), it is a single use object. All operations can potentially throw a \splitbrain\slika\Exception.

Options (see below) can be passed as a second parameter to the run factory.

Please also check the API Docs for details.

Operations

resize

All resize operations will keep the original aspect ratio of the image. There will be no distortion.

Keeping either width or height at zero will auto calculate the value for you.

crop

Similar to resizing, but this time the image will be cropped to fit the new aspect ratio.

rotate

Rotates the image. The parameter passed is one of the EXIF orientation flags:

orientation flags

For your convenience there are three Constants defined:

autorotate

Rotates the image according to the EXIF rotation tag if found.

Inspecting images without processing them

Sometimes you need to know what dimensions an image would have after a chain of operations without actually decoding pixels or calling ImageMagick — for example, to emit <img width="…" height="…"> attributes on a page that references a resize URL.

\splitbrain\slika\ImageInfo mirrors the Adapter's fluent API at the dimension level. It reads only getimagesize() and the EXIF orientation tag, never touching the pixel data.

This lets you predict the output of Slika::run(...)->autorotate()->resize(500,500) without doing any actual image work.

Options

Options can be passed as associatiave array as the second parameter in Slika::run.

The following options are availble currently:

Option Default Description
imconvert /usr/bin/convert The path to ImageMagick's convert binary
quality 92 The quality when writing JPEG images
