Issue
Sometimes you may want to generate images in memory, without the images being saved to an output file. Whenever you don't supply an $outputPath it errors saying
Undefined property: DarrynTen\Pslayers\Config\Config::$outputPath
, even though this option is optional. This is because it checks the property without fist checking if it is null.How I fixed it
I first checked if the $outputpath is set, then check if it is null. I also added tests that were failing before, but now pass as a result of this change.
