ClockSaverWin

Description:
ClockSaverWin is a recreation of the "KClock" screensaver usually included in the K-Desktop Environment (KDE) on Linux/Unix systems. It is an analog clock screensaver with customizable colors. You can have the clock move around the screen, or simply just sit right in the middle of the screen.

Internet Explorer is required is because the actual clock face and movement itself uses Vector Markup Language (VML) and Internet Explorer is used for rendering.

* ClockSaverWin was originally programmed in VDS 5, but earlier this year I moved it over to VDS 6 and completed it in VDS 6.

love it.. great screen saver. Is it possible to see the code.

There ya go... Eee, mind you, there's like absolutely no commenting at all in that stuff. Also, my style of coding may not be what you're used to. I'm a bit unorthodox I think. Anyway, have fun and I hope you can find something of use in there.

Garrett,

How would I speed up the secondhand to look like a rolex second hand smooth moving or say instead of 60 ticks maybe 240 per minute

I presume the below have something to do with it. Not sure how your math is working here.

secondsPointer.style.rotation = now.getSeconds() * 6;
LIST ADD,1, m01.style.rotation = 1 * 6;
LIST ADD,1, m02.style.rotation = 2 * 6;

etc

Also thanks for the source. Quite cool great job. I've learned alot from it already.

Hmmmm...... Lemme go back and look at the code again. It's actually been a long time since I played with the VML code itself. I actually learned a lot on the VML myself doing this. The original example wasn't very complete at all and I had to add a lot of stuff to it.

My bad, not the VML, it's all in the JS.

and the line to look at, which I'm trying to figure out now is:

Yeah... I can't figure out how to work in the milliseconds at all to get the effect you need. Sorry.

Ok.. I have to say, you GUYS ROCK!!!

but could you explain the code

LIST ADD,1, secondsPointer.style.rotation = now.getSeconds() * 6 + now.getMilliseconds() / 167;

what does the 167 do what is the math behind it?

Thanks again. I love this forum.

Briguy, now that Dave seems to have figured that part out for you, I can give you at least one more tip to aid in your effect.

Change the timer which is likely currently

I changed Daves code a tad and seems to work slightly better. 6 * 166.67 = 1000.02 value vers 1002. The clock worked but had a slight adjustment every minute if you stare it. LOL.. you would think I have something better to do then stare at a clock.

briguy,

I've noticed that sometimes, the first time that the second hand gets to 1 second paste the 12 o'clock mark it jumps back about 1 second. Changing 167 to 166.67 or even 166.66666666666667 makes no difference. Sometimes it does it, and sometimes it doesn't. Confused

Garrett,

Is it possible to easily add a text brand name onto the clock face? Or better yet, a logo image?

OK, a little googling has revealed that v:text and v:image are both possible. Any pointers on where to start?

Garrett · Posted: Sat May 16, 2009 5:09 pm Post subject:

I actually added text to it once when I was first experimenting, but ran into some problem doing that. But at the moment, I can't remember what the problem was. It's been some time now since I first started on this project and then it sat for a long time before I got back to it and finished it.

In the end, I didn't need any text on the clock to clone the KClock saver from KDE, so I never revisited testing with text on it.

If you do experiment, be sure to place the text below the Hour, Minute and Second arms.

Hit MSDN for the VML references. And remember, VML only works in MSIE, no other browser supports it.

I also found that when get down in dimensions of the clock, it begins to look bad, say under 100. I had some experiments that were 32x32 and 16x16, and could never get them to look nice no matter what sizes I used for the tick markers and arms.

And the reason I went with MSIE and VML is because it offered anti-aliasing, and the draw.dll for VDS does not.
