Jon00 HTML to Image Utility

[jon00]

Thanks.

I did wait until you posted again as it has been difficult to see if it was/was not working with your posts yesterday!

[Pete]

Yes; faded fast last night; age thing.

Testing to see how fast the updates occur on one touchscreen. Working well this morning.

Looking too to get my weather data graphs in some quick snapshot view. IE: maybe something like a 6, 12, 24, 72 hourly view of outdoor or indoor temps.

I can "build" the specific granular graphs with MCSTemperature; but its kind of slow so I might try the XAP on demand version. It would be a combo kind of set up utilizing your graphs application for a quickie snapshot with an additional granular snapshot using some specific ranges and time ranges.

The Chumby's now basically picture frames nestled in just about every "group" of picture frames sprinkled throughout the home; kind of blending in discretely yet HSTouch "functional" on demand.

I am trying to do a screen shot of the RFXWeather.aspx page and grab just the temp/humidity sensor graph.

Unfortunately because of the oddity of my LAN config with a FIOS router and my Linksys router on DMZ, I trust nothing into HS and force passwords on all requests, including local.

Up until now, that's not been a problem.

I want to inject user/pass into the url for localhost:<port>/RFXUSER/RFXWEATHER.aspx and then crop the resulting web page.

Any ideas / suggestions welcome.

[jon00]

I'm not sure I can help.

Are you saying that on your HS server/PC that every HS page viewed has to include a user & pass in the URL string?

[Pete]

I build my WUN weather cam picture with one radar picture using HTML. I then take the HTML image and embed it into a bigger image.

Using Jon's new html to image application and the older custom image application you can custom create any kind of image you want.

I keep the Infocast Chumby 3.5" pretty intact with little bit of mods to it. I use these images with widgets to provide up to date status pages running multiple Chumby widgets; kind of keeping the Chumby 3.5" lite.

Jon,

I am doing a screen grab of the mcsTemperature graphs. Currently testing an external program which uses a command line. The thing with mcsTemperature graphs is that it takes about 20 seconds or so to get the picture to come up and I was getting an error with your program:

The external mini program can be run from a command line so I can use it with Homeseer. The command line looks like this and includes a "timing mode".
It shuts down IE after a specified time.

I'm doing something for traffic capture using google with traffic layer. Here's the command:

iecapt --url="http://maps.google.com/maps?ll=<mylat>,<mylon>&spn=0.203733,0.527&sll=<mylat>,<mylo n>&sspn=0.203733,0.527&gl=us&vpsrc=6&layer=t&z=12" --out=c:\temp\rva_traffic.png --min-width=1600 --max-wait=5000 --delay=4000

I found out about the iecapt open source capture utility from these forums and really like that you can set the delay to whatever you want. Some iterating with max-wait and delay gets the data _most_ of the time. If the computer is busy or the network busy, it _may_ take longer. Setting it to 30 seconds might do the job for you.

[Pete]

Thanks Huggy.

The screen grab from mcsTemperature takes up to about 40 seconds some times. Its internal so I have to wait until the application creates the graph; then do the snapshot.

Does iecapt just capture part of the screen?

Here are the command line options of the program I am using.

[Pete]

Found another thing this morning with Weatherunderground. You can specify data with graphs from your own data; which works even faster; but you have to get the graphs from WUN. Its only one temperature though and not as flexible.

Here's all the graphs:



Then just one.

[jon00]

Pete,

I see you have your solution(s) so I'm not going to dwell too much on this. This was originally written to capture Homeseer device strings which it still does :-)

I would be interested if you can just try version 1.01 of my utility on a MCS graph.

You can now add the following under each [CaptureX] entry:

Delay=<numerical value in 1/10 second>

i.e.

Delay=300

Which should delay the grab for 30 seconds.

[Pete]

I'm still playing. I like the mcsTemperature graphs the best though.

I'll give it a try; it would be better to keep the capture to HS rather than utilize an external application.

Testing it see the following in the HS Logs. It is the JPG that's generated when it creates the graph. It changes though after a while.

Shouldn't the application though just be saving a snapshot of the screen?

The above was at a setting of 600.

I changed the setting to 400 and it looks to be maybe working.

It is writing the saved HTML image to the directory as specfied in the ini file. But its still doing the HS web server error thing as above.

But it doesn't show the web error every time I run it with it set to 400.

I do see these though maybe 10-15 minutes after I run the script.

This is great Jon! Much better than using an external program.

[jon00]

Pete,

Can you try 500, run the script once and then wait a minute to see if it appears without error.

[Pete]

Will do. Been playing. I have the jpg now posted with the Wunderground cam pic.

Before change to 500

It seems to be only doing it once after the event is triggered rather than 2-3 times as before. I'll let it settle a bit as I have it set to run every 30 minutes or so instead of manually running the event every couple of minutes.

Its still doing it; I am getting the images fine; even with the errors.

Pete,

It is strange that the captured page does not have images missing?

Can you find out what image this is?

If you load the graph normally, can you find it on the page?

...or how about just trying to load it by entering the following in your browser:

http://IPOFHOMESEER/mcsTemp/mcs19216...4Temp-OUT6.jpg

[Pete]

Here are some snapshots. If I load the page and look at the source; it shows that same link as the image. If I load the link as mentioned above while I have the page open it will just show the graph. If I close the page then open the link I can get to the graph; so it remains. Just checked (and I didn't remember if I had done so or not) the directory and it is in the directory. I've attached a picture. I had set it to grab the graph every 15 minutes last night. I checked the log this morning and it would show the error 4 times with every graph grab.

The HTML in the directory reads:

<HTML><HEAD><SCRIPT LANGUAGE='JavaScript'>function initialize() {setTimeout('restore()',60000);}function restore() {document.chart.submit();}</script></HEAD><BODY onload='initialize()'><form name='chart' action='/Temperature.asp' method='post'><input type='hidden' name='chart' value='redraw'><input type='hidden' name='Group' value='Temp-OUT'><input type = 'hidden' name='PriorGroup' value = 'Temp-OUT'><input type='hidden' name='EndDate' value='now'><input type='hidden' name='GraphStyle' value='All'><input type='hidden' name='Period' value='72Hour'></form><img src='/mcsTemp/mcs192168244234Temp-OUT6.jpg'></BODY></HTML>
