3. 11.x core/modules/system/src/Plugin/ImageToolkit/Operation/gd/Resize.php \Drupal\system\Plugin\ImageToolkit\Operation\gd\Resize::validateArguments()

Validates the arguments.

Image toolkit operation implementers should place any argument validation in this method, throwing an InvalidArgumentException when an error is encountered.

Validation typically includes things like:

• Checking that width and height are not negative.
• Checking that a color value is indeed a color.

But validation may also include correcting the arguments, e.g:

• Casting arguments to the correct type.
• Rounding pixel values to an integer.

This base implementation just returns the array of arguments and thus does not need to be called by overriding methods.

Parameters

array $arguments: An associative array of arguments to be used by the toolkit operation.

Return value

array The validated and corrected arguments array.

Overrides ImageToolkitOperationBase::validateArguments

1 method overrides Resize::validateArguments()

Scale::validateArguments in core/modules/system/src/Plugin/ImageToolkit/Operation/gd/Scale.php
