Hello all,

My first attempt at a new thread. Please be kind.

I already posted a similar message to the MadCap forum so the purpose of
this message is to explore this as a broader issue and hopefully discover
some best practices.

I am a brand-new (1 month) user of MadCap Flare, but a long time Adobe
FrameMaker and Microsoft Word technical writer. Recently, I have
encountered major issues with images when publishing a Flare project to a
PDF file. The problem is that, at less than 100% zoom level, images are
oddly pixelated (badly rendered).To add some clarity, my images are
generally inserted at slightly greater than 300 DPI. So, I am using
slightly higher than normal resolution... maintaining a balance of file
size vs image quality considerations.

I don't recall running into such image problems under Word or FrameMaker so
my finger is pointing is pointing at Flare.

After some experimentation, I found that by integrating GhostScript with
Flare, I can use .eps [vector] images, the results are images that render
perfect at all zoom levels, inside a PDF.

Part 1 of 2 solved! That is because the .eps format will obviously only
work on vector friendly images, like our corporate logo. Now, what do I do
about screen captures? Screen captures are a very important part of my
documentation. Any thoughts?


Thank you,
