To quote the classic TV commercial: Stop! You're both right! When speaking of raster images, the resolution is the *number* of pixels. It is *not* the pixel pitch, whihc ius what we're used to thinking of as "resolution" when we talk about monitors or printers.
What Richard is saying is precisely the advice you've always heard. The resolution--the number of pixels--should always remain the same for the best results. Changing the reproduced size changes the pixel *pitch* but does not change the *number* of pixels. The thing you do *not* want to do is resample the image to change the number of pixels (the resolution); this *always* degrades the quality of the image, anthough the degree of degradation can vary widely depending on the ratio of the two resolutions and the algorithm being used for the resampling or downsampling. And getting the size correct is actually very simple as long as you know how to use a calculator. If you have an image that is 1328 pixels wide, and you need it to fit in a frame that is 3.25 inches wide, you need to set the dpi (the pixel pitch) to 1328/3.25 ≈ 409. In this case you can actually set the size with 0.25% (one part in 400) accuracy. -Fred Ridder From: tp...@telecomsys.com To: richard.co...@polycom.com; framers@lists.frameusers.com Subject: RE: Importing clear, sharp images Date: Wed, 17 Jun 2015 21:30:04 +0000 OK this is very interesting. I was under the assumption that you should keep the resolution of the picture at the resolution of the screen, and then import it in also at that resolution. I was not aware that changing the import resolution was advisable. Off top of my head this seems like it would be difficult to get just the right resolution on the first try giving a particular anchored frame size. Do you have some clever method for getting the resolution right the first time?

Save as PNG exactly as captured. When you import them into FM, specify the appropriate DPI setting to make them the size you want on the page. From: framers-boun...@lists.frameusers.com [mailto:framers-boun...@lists.frameusers.com] On Behalf Of Tim Pann Sent: Wednesday, June 17, 2015 3:11 PM To: framers Subject: Importing clear, sharp images I'm using Frame 9 on Windows 7. And my apologies if this has been covered and answered. Can anyone point me toward a good resource (or just tell me if it's quick) for understanding how to get nice sharp images imported by reference in FrameMaker? I'm working on a doc right now in which I'm mostly importing PSD files. They're all screen captures of a user interface. I have to resize most of them and they're looking pretty choppy. I switched to a TIF image for one and that didn't help. I know that TIFF is the preferred format (not sure about PSD but many of my PSD imports look nice) but I don't know if there are specific guidelines or recommendations about resolution, resizing once imported, etc. I'm happy to provide more information about what I'm doing if needed. No idea what's relevant and what's not. Thank you, Tim CONFIDENTIALITY NOTICE: The information contained in this message may be privileged and/or confidential.
