[FM Discuss] Optimizing images for printing

[Cedric Gémy]

lo everyone

trouble with pictures for web is that they are 2 small for print purpose.
I'm actually trying to layout Scribus manual in Scribus and get low res
pictures even at small size (only halt of the page width). I was wishing to
do an XSLT conversion Script, but this picture quality is a pb that
actually stops me.

What we'd need is at least IMO :
- be able to upload full size pictures (which might not be enough, but
better)
- have an automatic resizing feature for the website, at least at display
if not applied to image itself (sources pictures could be stored in a
different directory PDF could une one directory and the screen formats
another one)
- save as PNG for best quality. JPEG is very bad with lines. That might
affect text too
- the right size of an image for print process is :
(widthinpixels*(targetresolution/actualresolution)) idem for height, but it
depends of the workflow you have
