I would like to increase the quality of the logo in the PDF invoices. At the moment I upload a logo exactly 200x50 px in size and with JPG quality 99 and it still looks terrible. I also tried PNG24 without any better results. If I upload a larger logo, it is embedded larger but the quality is still shit.
Could anyone point me in the right direction? I'm familiar with PHP and coding, if that is what it takes.
