Create small versions of document pages with legible text Apps
When doing marketing for my PDF book (Get Your Head Around Aperture 1.5), I needed high-quality page thumbnails to show what the pages looked like. I first tried taking screenshots and reducing the images in Photoshop, but that resulted in a horrible loss of detail and a very fuzzy look. The page size reduction was being carried out as though the image were a photograph, not a page of text. I needed a way of maintaining the character information through the size reduction.

To create the high quality page thumbnails, I first printed the pages I needed to a PDF file. Then, viewing the generated page in Preview, I reduced the page size until it was what I needed. Since the PDF was being rendered at the reduced size, the detail was still present. Last, I took a screenshot with SnapzPro2 and added a thin border and drop shadow with the media inspector in RapidWeaver. The end result is a small representation of the page with perfectly legible text.

Create small versions of document pages with legible text

I don't know about older versions. but Photoshop CS3 has an extra pulldown in the Image Size dialog, where you can specify what kind of image you're resizing. It also has a preset for extra sharpening for downsizing.

Wouldn't that do the trick?

Why resample?
Authored by: SeanAhern on Jan 07, '08 09:27:22AM

I'm a bit confused. Why did you resample the image smaller in Photoshop? If you just needed a smaller size, just change the size, and let the resolution change to fit. It almost sounds like you left the resolution the same, then resampled down to a smaller physical size.

Granted, re-rendering the vector text information at a smaller resolution is likely to give you the best quality, but I'm guessing you could have gotten much better quality out of Photoshop. The trick is to uncheck the "resample" button at the bottom of the "Image Size" dialog.

Of course, I could be misunderstanding the problem…

If you want to maintain the quality but reduce the size you should keep the format PDF. I think the easiest method would be to print this using preview but set "pages per sheet" to 8 or so. Then save the preview.

Correct way to create thumbails
Authored by: rumirocks on Jan 07, '08 02:32:21PM

This is the way you create thumbnails in Photoshop. It's the opposite of what you think:

(1) First blur the FULL image (select Blur or Blur More from the Filter menu)
(2) Then shrink it to thumbnail size using the Image Size item from the Image menu.
(3) Then, and only then, apply the sharpen filter to the thumbnail.
(4) if you have large amounts to do, automate the process using Photoshop's Action feature.

Create small versions of document pages with legible text
Authored by: JulesLt on Jan 07, '08 05:43:44PM

I'm just wondering how you used an OS 9 program to capture the screen!
(SnapzPro2).

More seriously - what's the advantage that SnapsPro X gives for static screen capture over Grab? (That's a serious question - I can see how it justifies the price for motion capture)

Why not just leave this as a PDF? When I layout booklets in InDesign I get printouts of pages as PDFs, place them on the page and size them as needed. Looks fine. Was there a particular reason you had to start with a bit map image in the first place?
