Subject: Re: [Homebrew_PCBs] Re: Toner Print quality

From: Donald H Locker <dhlocker@...>

JPG is quite poor at rendering images with sharp edges, so I would stick with
GIF or PNG. The JPG compression algorithm leaves what I think of as "visual
echoes" or ripples in the image. These are invisible in photographs, but stand
out with a vengeance in high contrast images with sharp edges.

Please note that I am very colour blind and see things differently. I have many
times experienced poor monitor quality (where I see obvious image artifacts)
that others don't have any problem with.

BMP is a an uncompressed format (i.e. bloated) and proprietary to M$, though
many programs can display such images.
