We need some changes done in the PDF that magento gives. I've looked at many guides and have found some solutions that work but are not really how I want it to be done. Many guides tell you to copy the files you want to edit, paste it in the local folder and make your changes there. But the changes are really small so I wanna know if there is a better way to make these small changes. The changes have to be done in these 2 files.
And all that we are going to change on these files are some colours. We could also override these classes but one of the classes is an abstract class. I am not sure if it's right to extend these and change them in local.
