Signature Quality

[eccharbonnet]

The signature is of course made up of linear segments. Is there a parameter that controls the size of these segments? Can they be made smaller so the signature looks more natural?

[thomasjbradley]

There's the penWidth option which may be what you're looking for.

[eccharbonnet]

So you think that will smooth out the rough edges?

I went into jquery.signaturepad.js and at the bottom of that file I changed the default on penWidth from 2 to 10 and then even larger. I see no change. I did save the JS file and I refreshed the web page and even flushed cache but I see no change. Are you thinking that a thicker pen will smooth out the polygon look? For instance, letters with rounded tops are being squared off. Letters with rounded edges are looking like 4 or 5 or 6 straight lines connected.

Many thanks

Is what you're describing happening on a specific device or on everything you're testing?

[eccharbonnet]

I'm testing on an asus transformer and Samsung galaxy 2. Both are tablets. The Samsung is running chrome browser, its native browser will not do signatures at all no matter what options are on. On Jun 15, 2013 9:35 AM, "Thomas J Bradley" notifications@github.com wrote:

That Asus is a transformer 101. Can the size of the signature canvas be an issue? It is not huge, but it is larger than your default. On Jun 15, 2013 9:47 AM, "Edward Charbonnet" edc.charbonnet@gmail.com wrote:

thanks for your feedback and interest. I'm traveling this week but how about after that I collect more exact data for you? On Jun 15, 2013 10:29 AM, "Edward Charbonnet" edc.charbonnet@gmail.com wrote:

My thought is that it is something related to Android. I've heard a couple other people mention that Android is a little laggy when drawing. After researching, it appears that Android doesn't fire the move event very quickly—it's even worse in embedded web views.

[eccharbonnet]

Interesting, I'll do more research and share with you very soon. On Jun 17, 2013 8:35 AM, "Thomas J Bradley" notifications@github.com wrote:

As promised, I have collected information on the following Tablets. I am planning to obtain opinions from other folks as well. I hope you can open this WORD attachment.

I am puzzled why the Samsung should be a problem - I have high regard for the company. I am working to try this on their Galaxy Note Tablet. Please let me know if this data is helpful.

Thanks for spending so much time on this! I don't see your document though; do you want to e-mail it to me directly?

I have the same problem. To sign is very slow on most devices. I already tested galaxy tab 4 10" and Dell Venue 7. It worked well on my iPad Air 2, but just for signature it's to expensive :-)

You have some ideas how to speed up?

Regards H

[eccharbonnet]

Wow. Caught me by surprise here. Have not been contacted on this old issue in some time. We are running very well most of the time on Amazon Kindles.

Samsung Galaxy's worked for a while and then also got slow. We joked that they ran out of ink. The pattern we've noticed is described below and I'd love to better understand it.

Once I downloaded Chrome onto the Samsung instead of using the default browser, I did not have a speed problem anymore. And the default browser worked early on but not after a Samsung update.

So there seems to maybe be a subtle issue on certain browsers. We even noticed that if we refreshed the page then sometimes it would work. It almost seems like a subtle timing problem with maybe when the canvas get initialized compared to some other init process.

Your email is cdn123 and signature is H. Can I know anymore about you?

Thank you for your fast reply. I try to use your signature to sign a service report. Acutal it's a beta project. Yes it feels like, that they have timing problems. The resolution seems to be very ok, but it's too slow. After finishing the signature you have to wait for 1 sec to see the whole signature. You have any idea to fix this? You are using a kindle fire and this worked well? You have experience with windows tablets?

[madmanpierre]

I’ll jump in as a user and past really tiny contributor.

We use signature-pad on Windows Tablets – both RT and Pro, Windows phones, Windows laptops, Android phones and Tablets including Kindle fire – but we always use the Chrome browser, we told our customers years ago we don’t support the ‘default’ browser that Android manufactures install..

We have not seen any slowness like you mention on any of our test devices and have yet to have a customer complain about performance.

We only support:

•    IE (current versions), Chrome, FireFox on Windows

•    IE on Windows RT

•    Chrome on Android

•    Safari and Chrome on iStuff. (Note Chrome on iStuff is not ‘real’ Chrome, it’s Safari with ‘chrome’ that makes it called ‘Chrome’)

Though we only occasionally test in Opera and SeaMonkey and had no problems the last time (several months ago.)

But as I said, we explicitly do not support any ‘default’ Android browsers – we had too many other problems unrelated to signature-pad to even attempt to test signatures, so I can’t comment or give any opinions on those.

I do acknowledge that my customers might consider 1 second to redraw to not be a problem so it is possible some of our customers have the slowdown and haven’t reported it to us. Our users are all signing work reports, and sometimes they sign multiple times at different stages – it is a Maintenance Management system. So, while it is possible, it would seem to me if they aren’t seeing instant feedback while they sign, that they would have complained! My signature I draw the outer whole first, then fill in the middle – so I could not possibly draw my signature without seeing what I am drawing instantly.

I hope that helps you narrow down the problem.

I totally agree that as long as we stay away from the android default browser we've had no difficulties. We have no experience using this on Windows Tablets.

This is really strange. Did you test with android 4.4? I tried to use chrome, dolphin, opera, firefox. No improvements :-( So the default browser of android is the fastest one to use the signature.

Maybe it's about the android version 4.4 kitkat?

[eccharbonnet]

We are at this time entirely focused on the Kindle from Amazon and its version of Android. Not sure what that is. But it works very smoothly.

I just tried it on my Android 4.4.4 machine, using chrome 34.0.1847.114. Moto G (fairly slow phone for modern smart phone – I usually buy fairly slow ones for testing) Says total space is 5.5 Gig. Lots of free memory (about 80%).

The signature is instantaneous, following my finger as I sign.

OK. I'm using Dell Venue 7 with Chrome v35. I've made 2 videos. First with my dell, second with my iPad. Can you confirm the slowness on reaction? http://www.yourfilelink.com/get.php?fid=1053788 http://www.yourfilelink.com/get.php?fid=1053789

[hesne]

Can you agree with the speed with your experience?

[eccharbonnet]

I've had no luck trying to see these videos. When I go to the forum and click on your links they just take me to a place that wants me to download a FileLink application.
