Learn how to migrate from Intervention Image version 3 to version 4. See what new features are available and what changes have been made in the update.

New Features

New Decoding Methods

The revised image decoding interface introduces a more transparent approach to handling image sources. Allowing image sources to be addressed directly instead of relying on a single universal method.

  • ImageManagerInterface::decode()
  • ImageManagerInterface::decodePath()
  • ImageManagerInterface::decodeBinary()
  • ImageManagerInterface::decodeBas64()
  • ImageManagerInterface::decodeDataUri()
  • ImageManagerInterface::decodeSplFileInfo()
  • ImageManagerInterface::decodeStream()

Exceptions and more detailed Error Messages

At the same time, error and exception messages have been refined to provide clear, immediate insight into what went wrong. These improvements include a restructured exception system with a well-defined hierarchy that makes handling exceptions easier.

API Changes

High Impact Changes

It is very likely that you will need to make these adjustments when you update to version 4.

Medium Impact Changes

It is possible that you will need to make these adjustments when updating if you have delved deeper into the functions.

  • Removed ColorInterface::toArray() use ColorInterface::channels() and map to desired format
  • Removed ColorInterface::normalize() use ColorInterface::channels() and map to desired format
  • Changed default value for background to null in ImageInterface::rotate()
  • Changed default value for background to null in ImageInterface::resizeCanvas()
  • Changed default value for background to null in ImageInterface::resizeCanvasRelative()
  • Changed default value for background to null in ImageInterface::contain()
  • Changed default value for background to null in ImageInterface::containDown() former ImageInterface::pad()
  • Changed default value for background to null in ImageInterface::crop()
  • Signature of ImageInterface::crop() changed from offset_x to x and offset_y to y
  • Attribute $per_unit has change to $unit with different signature in Resolution::class
  • Method DrawableFactoryInterface::init() is replaced by DrawableFactoryInterface::create()
  • Method DrawableFactoryInterface::create() is replaced by DrawableFactoryInterface::drawable()

  • FontInterface::setAlignment() was renamed to FontInterface::setHorizontalAlignment()
  • ImageInterface::greyscale() was renamed to ImageInterface::grayscale()
  • ColorInterface::isGreyscale() was renamed to ColorInterface::isGrayscale()
  • Alpha channel values in __construct() or create() methods of colors are now defined as float values between 0 and 1
  • FrameInterface::dispose() was rename to FrameInterface::disposalMethod()
  • FrameInterface::setDispose() was renamed to FrameInterface::setDisposalMethod()
  • ImageManagerInterface::driver() was removed but you can use the public $driver property.
  • FileInterface::toFilePointer() was renamed to FileInterface::toStream()
  • Color format string transparent is no longer supported. UseIntervention\Image\Color::transparent() instead

Low Impact Changes

  • Replace DriverInterface::specialize() with DriverInterface::specializeModifier(), DriverInterface::specializeAnalyzer(), DriverInterface::specializeDecoder() and DriverInterface::specializeEncoder()
  • DriverInterface::handleColorInput() has null as default
  • Signature of FrameInterface::__construct() has changed, argument $offset_left is know $offsetLeft and $offset_top is now $offsetTop
  • Signature of PixelColorAnalyzer::__construct() has changed, argument $frame_key is know $frame
  • ColorChannelInterface::max() and ColorChannelInterface::min() are now static
  • Method ColorChannelInterface::toInt() was removed use ColorChannelInterface::value() instead
  • Method ColorChannelInterface::colorFromNormalized() requires now a static implementation
  • Method ColorChannelInterface::normalize() was renamed to ColorChannelInterface::normalizedValue()
  • CoreInterface::class now requires implementation of CoreInterface::meta()
  • RectangleResizer::class was renamed to Resizer::class
  • GreyscaleModifier::class was renamed to GrayscaleModifier::class
  • DrawableFactoryInterface::__invoke() was removed, use DrawableFactoryInterface::build() or DrawableFactoryInterface::drawable()
  • FontFactory::__invoke() was removed, use FontFactory::build() or FontFactory::font()
  • AnimationFactory::__invoke() was removed, use AnimationFactory::build() or AnimationFactory::animation()
  • InputHandler::withDecoders() was renamed to InputHandler::usingDecoders()
  • Interface ColorInterface::class now requires to implement ColorInterface::withTransparency()
  • Interface ColorInterface::class now requires to implement ColorInterface::alpha()
  • Removed topLeftPoint() and bottomRightPoint() from Rectangle::class
