you could enlarge the image as much as you can before taking the screenshot. That's your best quality there.

how to calculate this? in which zoom can you extract the above scheme?

sorry Kalos, I dont understand your question.

let me rephrase:
if the image is vector (NOT a pixel image) simply enlarge it as much as you can on your monitor, then take a screenshot.


[edit] you can then increase the dpi of the image to show it at a smaller size & higher quality [/edit]

-the picture will not be vector, because kalos is talking about taking a screenshot; a bitmap. If the files are like the test file, I *imagine* size 150% will be fine. But it doesn't make sense to talk about borders; since there are no genuine pictures, there will be no natural borders.

indeed, one can "imagine" that 150% "would" be fine, these are the problems I need to overpass

as for natural borders, since there is no picture file ofcourse they don't exist, but I think PDF editors do great job in determining borders than an individual can do by draggin his mouse over the to be captured area

[...]

Yes, of course the screenshot is going to be a pixel image.
But I'm talking about what the 'picture' is *in the PDF* - if it's a vector graph or image in the PDF, then do what I suggested above for best quality [screenshot] image.

there is an amazing pdf editor that before taking the snapshot it asks you at which dpi you want to take it

but cant remember which editor is it

any hint?

the problem is that when i need a high resolution snapshot and i zoom out much, the are that i want to capture goes out of the monitor, so i have to scroll

so there is a pdf editor that enables you to first specify the area you want to capture, then specify the resolution and it zooms outs itself and then takes the screenshot

-zoom out, all you want, and use your screen capture application.

I'll admit I only skimmed this topic, so this may be wildly far of the mark, but what about opening in Photoshop and rasterizing at desired resolution, then cropping? Given that screenshot approaches are being talked about here, I take it having the tables, etc. in actual original format (i.e. being translated into a Word table) is not a requirement, thus the Photoshop approach should work well (if I've understood the requirement from reading first few posts and skimming the rest  :-[).

Hi all,
let's see, if anyone is still looking at this thread. I stumbled upon this while checking on answered postings.
1st: Can't pdf be saved as html? I think having done this. But it may have been with Acrobat Full version. It's not for the faint of purse. Advantage: text is html, images are saved separately.

2nd: One of the very good screenshot programs with a scrolling option is - apart from the incomparable screenshot captor - HyperSnap from hyperionics.com. Region with scrolling, windows with scrolling, text with scrolling, almost everything.
Give it a try, if you never heard about it.

where did my post go? I am certain that I proofread it after uploading. Have DC been hit by something today?

-good point, Thomas.

I have a key for HyperSnap 6, but am "merely" using FastStone Capture, because it is so delightful user-friendly. However, HyperSnap 7 seems so far to become much more user-friendly than version 6 has been:

Version 7 beta tests started, and we currently have a poll for users to vote on new features to add to version 7 of HyperSnap. More information at HyperSnap Feedback and Beta Tests Forum.
