What do you mean by "measure" a pdf document? I don't understand. I could be being thick! Steve

Say you have a scale drawing of a ramp. Adobe's measuring tool allows you to find out what the actual, physical length of that ramp will be. Phil suggested (off list, I think) PDF Studio Viewer but I'm not sure it works in the way I was hoping. There's not much choice, to be honest. (As far as I can tell.) Bev.

Ah, I was unaware you could do that. Open Office Draw has rulers, so you might be able to work it out. Inscape has a measurement tool. Not entirely sure if it would help. Click on the start point and drag to the end & it shows you dimensions of points it crosses in pixels. I don't know if that helps. It also imports the PDF so I guess its size may change. Good luck.

i've been watching this thread to see if something interesting would come up. So far, nothing special (and no assurance that the suggestions made would work). So, Bev, here is the approach I would use (since deacdes ago) for this kind of task. This is very "bare hands" and could involve writing on paper ... Bex: You say "Say you have a scale drawing of a ramp". Not sure what this kmeans. [A]Is there a scale indicator (e.g. a line with spaced tics, representing the scale relative to reality)? Or [B]is it independently stated that, if printed, the PDF as printed would be in a certain scale relationship to reality? In case [A], it would suffice to measure the PDF size of the object and the PDF distance betweem tic-marks. In case [B], it would be necessary to somehow relate the PDF to the printed size. Either way, I would convert the PDF to PS Set Acrobat Reader (or whatever) to print to a PS file Page Scaling: None Print to File xxxx.ps Then open the PS file using 'gv': gv xxxx.ps On top is a series of buttons, one of which is raw display scale (default 1,000m but offering seceral from 0.100 uo to 10.000), Now it is a matter of countibg pixels (left-righ, bottom-top). The pixel coordinates for where the cursoe currntly is are displayed on a little box (2nd down) on the left). Positioning the cursor more precisely relative to pixel resolution if helped by using lerger display scaling. As you move, the cursor around, the displayed coordinates vary. You cn now mesure the vertical difference between two points, and the horizontal difference, in pixels. This can then be used to obtain the length of the straight line joining them: lrngth = square-root(horizontal-squared + vertical-squared)/ It renains to convert this into "real" measurements, In case [A], you can also measure the pixel-distance beteen the tic-marks. Then you can convert the lengths into real distances. in case [B]. you need to know the r4latioonship between pixel length and printed length. This is not readily available, since PS (and PDF) are not "pixel-based" -- that is left to whatever is used to print or display them. I'm not sure how to approach this; perhaps by aimply printing out the page and measuring thibgs on it, then relating these measurements to the pixel counts. But, by the time you've printed and measured it, in case [B] you're already there1 Hoping this helps. Don't get too pixilated, Bev![**] Best wishes, Ted.

<snip> Say you have a road atlas or other map. These are printed to say, one inch to a mile. Likewise with planning drawings. It might say Scale 1:10 @A1. Is that any clearer? Further googling indicates that some Linux bod will have to write a program to do this as there's only Adobe and PDF Xchange and the latter's not Linux friendly and there's no sign of it ever being so.

<snip> Coming back to this thread as I need to ask something related. I've now got Foxit Reader which is one of the best pdf programs I've seen so far. However, whither the measuring tool? It should be under 'comment'. Is it down to not having Adobe Flash that it won't play ball or that I've got a Linux version? Really puzzled. If this is off topic, please shoot me gently.

P.S. Sorry, me again. If you want to answer this feel free, but on consideration, I've uninstalled it. Seems a bit of a risk having something isn't straightforward to remove. Bev.

Dear Bev, On the (not very frequent) occasions when I have needed to measure a PDF (or a PS) file, I have used the following (admittedly primitive and a bit fiddly) method. If it's a PDF file, convert it to PS (PostScript). Then open it using ghostview (gv), e.g. gv myfile.ps In the left-hand margin under "File" you will see a small slot (2nd down) within which, as you move the cursor arounf the image. you will see a pair of nunbers varying (they disappear when you move the cursor off the image), The first number in the pair is the horizontal coordinate of the centre of the cursor (in units of points, 1/72 of an inch) and the second is the vertical coordinate. Depending on how the file was created, the vertical zero may be at the bottom of the inage (the usual case) or at the top of the image (less usual). Also, it is possible that "1st horizontal, 2nd vertical" may be reversed, So you first need to move the cursor around a bit to make sure of what it happening. Now you can observe, and then record (by writing them down or by typing them into a file) the coordinates of any any chosen point in the image. Repeating this for other chosen points gives you the coordinates (x,y) of each of the chosen spoints. Now the distance from any of the chosen points, (x1,y1), to any of the others, (x2,y2) is simply the square root of (x2 - x1) squared plus (y2 - y1) squared, again in units of 1/72 of an inch. So now you can measure your file. Finally, just to make it clear: these distances are the distances you would measure on the shhest of paper, if you printed the file. They are independent of the magnification with which you view the file using gv. So to locate the cursor more precisely, you may find it useful to increase the magnification (4th button on the top of the image). Hoping this helps (and apologies if you've already been there, and are looking for an easier method). With best wishes, Ted.
