measur3r v1.3 - onscreen measurement in pixels, cm, inches
measur3r v1.3 - onscreen measurement in pixels, cm, inches
With this app you can measure objects on the desktop.
Just launch it, click on point A, click on point B and enjoy the results.
You'll get coordinates of A & B points, a distance between them in pixels, centimeters and inches, and additionally a distance relative to X and Y axes.
Requirements: bash, xwininfo, xrandr, getcurpos, awk, which (g)xmessage
EDIT: attached also measur3r_lite, which supports only pixel units, not cm/in.
For those for whom the regular version can not read the physical display size and who are unable to determine that size by themselves (or just don't need/care about cm/in).
___________
Changelog:
Version 1.1
- a warning window in case if obtaining the physical size of the display has failed (thanks to Jasper & mister_electronico)
- physical size of the display can be also defined manually in $HOME/.measur3r
Version 1.2
- fix in calculations for screens that have width smaller than height (thanks to MochiMoppel)
Version 1.3
- added 'Repeat' button (thanks to charlie6)
- better compatibility with _real_ xmessage
Have fun &
Greetings!

Hi SFR
Hi SFR the program seems very interesting, but can not get it to work.
If I run through terminal gives me the following error
awk: fatal: division by zero attempted
awk: fatal: division by zero attempted
I am working with Slacko Puppy 5.6 Non-PAE.
I find it very interesting.
Greetings!

Hmm, I think you're facing the same problem as Jasper here: http://www.murga-linux.com/puppy/viewto ... 820#831820
I've no idea why in my (and MochiMoppel's, and Geoffrey's) case xrandr reports real screen dimensions and in your and Jasper's not...
Anyway, as a workaround you could (if you know your display's actual dimensions, in millimeters) alter the code and hardcode these values right after this line, e.g.:
Thanks for you interest &

You are in true.
Hi SFR you are in true, I don't know why :
read MM_X MM_Y <<< `xrandr | grep -wo -m1 '[0-9]*mm x [0-9]*mm' | tr -cd '[0-9]x' | awk -F "x" '{print $1" "$2}'`
do
MM_X = 0
and
MM_Y = 0
But like you said I change :
MM_X = 320
MM_Y = 200
Is my case:
#xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 1920 x 1920
VGA-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1920x1080 60.0*+
DVI-0 disconnected (normal left inverted right x axis y axis)
and works...
So thanks SFR .... good program.

Hi SFR,
this is really an awesome app ! thanks for it also !
I regularly reads drawings on screen and have to estimate dimensions ...using a ruler and doing measurments straight onto the screen and performing some cross-multiplication to convert to real size...etc,etc,etc,...funny isn't?!
In ordre to repeat successive measuurments using measur3r, here is what i've found to repeat measur3r start without having to each time select it in the menu.
replace line 69
by the following 6 lines
HTH
Charlie

Nice app. I find the lite version works for me as the full version (and rul3r) gives me the following output:

Yes, in some cases, I don't know why, xrandr doesn't report physical size of the display (see my post above).
If you know the real dimensions, just follow the instructions (echo "X_MM Y_MM" ...).

Just a note - xrandr is an extension which all drivers (Xorg drivers) don't necessarily support. (vesa, modesetting, fb etc)
here is a C snippet that gets it - use with caution (wont work over hdmi)
Dunno if there is equivalent lib in bash.

Thank you SFR!
I just needed to compare two distances in (generally) non-vertical or non-horizontal directions on-screen, and measur3r 1.3 seems to have done the deed for me in terms of pixel distance results. Cheers!

Huh. I never saw this before. It works fine in Quirky Werewolf 64-bit.
I have two suggestions: 1.) The point of the arrow I use for a cursor would be more accurate for finding a pixel than is the cross that measure3r uses - the cross is kind of broad. And 2.) Wouldn't this be better in Graphic, not Business?
But it really works well for me. Thanks, SFR!
I was able to move the window by dragging its edges to where I wanted them.

I don't really have control over it - the shape of the mouse pointer comes from xwininfo utility, which is used by measur3r to aquire screen coordinates without interacting with what's on screen.Flash wrote:The point of the arrow I use for a cursor would be more accurate for finding a pixel than is the cross that measure3r uses - the cross is kind of broad.
Yep, Business doesn't fit, indeed...but it's in Engineering/Science/Simulation.Flash wrote:Wouldn't this be better in Graphic, not Business?
Yeah, in some window managers (Openbox, Compiz) (g)xmessage's window has titlebar, but in JWM it doesn't, because of this (usually in /etc/xdg/templates/_root_.jwmrc, but YMMV):Flash wrote:I was able to move the window by dragging its edges to where I wanted them.

Ah yes - in my haste I didn't provide testing details - I'm running measur3r in TahrPup32, v6.0.5, using the JWM environment. My screenie confirms Flash's observation that it winds up in "Business" - but it does the business, I guess. "Graphics" would also be my preference, all things considered.
(or I could rename my "Business" menu category more appropriately as "Science". No dramas...)
Flash refers to an issue I had reported to in another thread (http://murga-linux.com/puppy/viewtopic.php?t=111913) concerning the output dialogue. I will try the ALT+left click again in JWM to move it to a more practical location than center screen,
Cheers!

OK so Alt+left_mouse works a treat, thanks. Found that I can have multiple instances of measur3r going for immediate comparisons. In the example below I have a measure for the distance between two wires, illustrated by the white rectangle, in the dialogue to the right. On the left I have projected the width of the feed bunk at that distance (with due estimation of the vanishing points), shown in the red line (hmm looks off by about 2-3 degrees of rotation, seeing it from a distance). This image was made by using PrtScn and then adding the measurement lines in mtpaint 3.44.88, all done in TahrPup 6.0.5 (32bit) and JWM. Hope others find this really useful
PS I can even highlight select text in any dialogue - in grey and not shown here - but unfortunately only one dialogue will have the highlighted text at any one time. No biggie

What Flash means is that it appears in the "Business" portion of the main Puppy menu (rather than referring to which "murga forum" subsection).SFR wrote:Yep, Business doesn't fit, indeed...but it's in Engineering/Science/Simulation.Flash wrote:Wouldn't this be better in Graphic, not Business?
!
"Business" is probably a reasonable place for it since "calculator" is also there... but why isn't there a "Technical" subsection to the puppy menu? Thats where the Calculator and Ruler functions really should be. (Maybe it's an XDG or similar limitation - dependent on the big distros?)
RE: Business
Yeah, I got it now, sorry!
Intentionally it should go to 'Calculate' submenu and it does, in Fatdog.
In Puppy however /etc/xdg/menus/puppy-calculate.menu is a symlink to puppy-business.menu, that's why it ended up there.
But still, that's where all other calculating apps reside...
