Problem in setimage

[Alan Hendry]

HI,

Getting error - cannot read properties of null  (reading setimage)

Regards, ah

    i4 = app.AddImage(lay2,"ds:/Sys/Img/Pillar.png")
    i4.SetImage( "ds:/Sys/Img/Pillar.png")

This is because the "ds:" scheme is for HTML elements, as the doc says:

Support for ds:/* style paths in HTML elements (eg. ds:/Sys/app.js).

Removing "ds:" seems to fix your issue.

HI,

Whoops copied it from elsewhere.

The original aim was to try and load an image from the web.

That gives me the error.

I tried to app.Uri2Path, and that failed too.

I get confused enough about what paths work where that  I now keep in my pastebin a function checkPath to see if the lath I'm using is valid

I suspect this may not be guaranteed to work in future versions but in the past I've caught all sorts of stupid mistakes with it

function OnStart() {
   lay = app.CreateLayout("Linear", "VCenter,FillXY")

   txt = app.AddText(lay,"?", null, null, "Left,Multiline")

   //Add layout to app.
   app.AddLayout(lay)
   path1 = checkPath("ds:/Sys/Img/Pillar.png")
   path2 = checkPath("/Sys/Img/Pillar.png")

   txt.SetText(path1+"\n\n\n"+path2)

}

function checkPath(path) {
   var sep = "\n------\n"
   var rp = app.RealPath(path)
   var exst = app.FileExists( rp )?"exists":"does not exist"
   var ret = path + sep + rp + sep + exst
return(ret)
}

HI,

Is it possible to use a web URL in a DS Image?

I tried         "https://upload.wikimedia.org/wikipedia/commons/thumb/9/90/Hapus_Mango.jpg/220px-Hapus_Mango.jpg"

and Uri2Path

Currently working around it by opening a webview, I'd like to get the proportions correct.

Hi,

To show a picture on the internet, I think it can be done with the SetData parameter of the Image object by taking the picture with fetch in JS and converting it to arrayBuffer.

There is a plugin for this: https://play.google.com/store/apps/details?id=com.candlelight.picasso

Probably a better idea to download from DroidStore but I couldn't get to the page right now.

HI,

This phone isn't compatible with this app.

You can find it by searching for Picasso on the DroidStore (https://ds.justplayer.de/).
