To know the pixel size you required, you first need to know how large
the image will be when printed, and you multiply that by the DPI setting
of the print.
A large, A size, print should need about the same pixel size as a
smaller size A2 print. Normaly, you look at the larger print from
farther away, so you can get away with a lower DPI setting. Just look at
a billboard from normal distance and close up. It may have a PDI of
about 0.5 to 2 ...
Once it's done, you just start the render with: +wxxx +hyyy -d +fn
xxx and yyy are the horizontal and vertical pixel dimentions. You are
never limited by the resolution from quickred.ini, you can render to any
arbitrary dimention you chose.
-d suppress the display window under windows and mac. Usefull when you
render at a very large resolution.
+fn set the output format to png.
As you have large areas of uniform tint, you'll get a good compression
ratio: Large image, small file.
