Measure pixels on your screen.

A virtual ruler! It's a useful tool for web designers and maybe for others too Simply click the grid in two places to measure the distance between the points (in pixels). To remove the points, click again. You can create straight lines with Shift key. You have to right click this widget to close it, because it covers the whole screen.

A simpler version of the ruler is included for Linux users, because widgets on Linux have problems with transparency. It will be detected and enabled automatically if you don't use Windows or Mac.

really nice. I think this tool could be a point of start for a nice widget development.

e.g.
- it could be enhanced by capturing the #HEC color you're clicking on
- One button somewhere in the space to abort
- some loop function, to be more precise.
- working on multiple monitors

@jsabarese: More or less. The Linux version is very different (and unfortunatelly - limited). It's because the whole idea of this widget was to have a translucent grid which cover the whole screen. On Windows and Mac you can click any point of the screen to measure the distance between the points. It wouldn't work on Linux, because widgets on Linux can't be translucent.

Grafio, thanks for a great, useful Widget. Let me make sure i have this clear-- the same "identical" widget is not really identical in terms of its behaviour in XP vs. Linux?

the XP version will mearsure both X, Y axis lengths, but Linux version will only measure along the X axis? is this correct?

thanks!

It doesn't work properly on linux. There is no problem with transparency but only horizontal ruler is available. I can't measure vertical distances or across the screen

@Jurgi: It's because widgets on Win98 don't have transparency. Sorry...

By grafio, # Jul 25, 2006 7:58:58 PM

Hm, it does not work. Yes, it takes a measure, but I get the whole screen blank black. Only Windows taskbar remains (sometimes).

By Jurgi, # Jul 22, 2006 7:12:19 PM

I'd love to see better Linux version too. Oh and transparency doesn't work on windows 98 as well, all I'm able to see is black background and the ruler, though it works fine.

Thanks for the ideas, CrazyTerabyte. I will improve Linux version in the future.

By grafio, # Jul 14, 2006 1:35:38 PM

As a Linux user, can we rotate the ruler, to use it vertically?

Maybe add two rulers, one vertical and one horizontal.

And also it is important to be able to MOVE the ruler (ok, my window manager allows me to use alt+mouse).

Maybe even the not-linux versions could use this "simplified" interface (by an option)

Also, drawing a ruler with numbers on them might be useful.

Useful! Useful!

Nice widget. Thanks.

Many thanks for the valuable tips, Benjamin Joffe!
I'll update it today.

EDIT: Done

By grafio, # Jul 8, 2006 2:09:41 PM

I like the idea. Here are a few suggestions.

- Make it not possible to drag using the CSS:

 -apple-dashboard-region: dashboard-region(control rectangle 0px 0px 0px 0px);

- It seems to be quite laggy, I assume that this is because you are using canvas and are clearing the entire rectangle instead of just the line. To clear only the line more efficiently you should stroke over it again with a wider line and use the javascript:

ctx.globalCompositeOperation="destination-out";

- Place the points using onmousedown instead of onclick to make it more responsive to the click.

VERSION 1.6: Now you can use Shift key to create straight lines. Thanks to d.i.z. for this idea
