help - changing an image from a string in HS

[collegeboyslive]

i have an image i want to display on the hs touch screens, it comes from a url like this: http://www.test.com/IMAGE.jpg

that is simple enough BUT the name for this image changes. I have a script that loads the new name into a status item in HS say A1 contains ste updated string http://www.test.com/NEWIMAGE.jpg

how can i get it automatically updated on the hs touch client?

thanks

What does the device string look like in A1? You should be able to see a device in HSTouch to status tracking and it should change if the status of A1 is changing.

Why not download the image using GetURLImageEx and always call it a static file name? That way in HSTouch you could always point it to one address.

you might need to set isvideo = yes. Dynamic images are tricky, depending on the exact way you set them up in HST.

Rupp, i want the image to update BUT i want the NAME of the image to be pulled form a string held in a1

so string A1 ome moment could be " http://www.test.com/images/image1.jpg"

the next time a1's string could have changed to " http://www.test.com/images/image1534.jpg"
( note homeseer is given the image information from an extrernal server and holds it in the string A1 )

i cant cause the image keeps changing on the external server

Here I am doing this sort of with weatherxml. I download the image with HS, save it on the HS drive then the HSTouch clients pick it up (its a gif) and I am having wierd problems where the HSTouch clients en mass get it and errors. Personally I do not want the clients to to to the internet for the same image. (preference here would be that none of the clients ever talk to the internet - that is me though).

I just set that string to a device, then have HST use that device as the image. I don't have things changing in real time (weather inputs), but I also do not leave HST open long enough to see the image change. Each time I load HST it pulls the image fresh and it always seems to change for me.

Yeah; here I didn't see this issue crop up until I took the number of clients up from 2-3 to 8-10. Its not really an issue other seeing the time out entries in the HS logs.

aah i think i understand our confusion here. i dont HAVE the image in the value on the device A! , rather under status i mearly have the url displayed "http://test.com/images/zs.jpg"

how can i grab an image from a website and import it into the value of a device? i tried

hs.DeviceValuesGraphicsAdd "A1", "http://test.com/image/jj.jpg"

but that didnt work,

I don't know about "automatic" updating, but if you can save the image to a file on your HS PC, then you can use a simple script to update an image element on a HSTouch screen. This is a snippet of a script I use to update cover art:

Dim newfilepath As String
Dim hstplug as object
hstplug = hs.plugin("HSTouch Server")
filepath= "however/wherever you save the picture to your machine"
hstplug.ClientAction(43,"","Music:CoverArt",filepath)

Obviously, you would need some additional scripting to come up with your filepath.
