`checkMemoryForImage()`

Determines if there is enough memory to process this image.

The code was adapted from http://www.php.net/manual/en/function.imagecreatefromjpeg.php#64155. It will first attempt to do it with available memory. If that fails, Craft will bump the memory to amount defined by the config4:phpMaxMemoryLimit config setting, then try again.

Arguments

$filePath (string) – The path to the image file.
$toTheMax (boolean) – If set to true, will set the PHP memory to the config setting phpMaxMemoryLimit.
