1. 8.0 core/modules/image/src/Entity/ImageStyle.php \Drupal\image\Entity\ImageStyle::transformDimensions()

Determines the dimensions of this image style.

Stores the dimensions of this image style into $dimensions associative array. Implementations have to provide at least values to next keys:

• width: Integer with the derivative image width.
• height: Integer with the derivative image height.

Parameters

array $dimensions: Associative array passed by reference. Implementations have to store the resulting width and height, in pixels.

string $uri: Original image file URI. It is passed in to allow effects to optionally use this information to retrieve additional image metadata to determine dimensions of the styled image. ImageStyleInterface::transformDimensions key objective is to calculate styled image dimensions without performing actual image operations, so be aware that performing IO on the URI may lead to decrease in performance.
