Android Question Create Circle Imageview After Download images

[PumaCyan]

I have a list of data using CLV
and there is a downloaded image
but I have difficulty in making the image into a circle after the image download process is complete.

Does every picture that is downloaded must first be saved in memory to make a circle? then called locally?
I have also used the XUI round image module.
but i am still confused to apply it ...

I have already implemented it from This thread
but it might be quite troublesome if every image must be saved locally first

What does it mean "saved in memory"?

Code to make a round image: https://www.b4x.com/android/forum/threads/b4x-xui-create-a-round-image.85102/#content
Note that it is better to reuse the canvas if you plan to deal with many images.

What does it mean "saved in memory"?

I mean, like this :

Sub DownloadAndSaveFile (Link As String)
    Dim j As HttpJob
    j.Initialize("", Me)
    j.Download(Link)
    Wait For (j) JobDone(j As HttpJob)
    If j.Success Then
        Dim out As OutputStream = File.OpenOutput(File.DirInternal, "temp.png", False) ' <--- does this is save in phone ?
        File.Copy2(j.GetInputStream, out)
        out.Close
    End If
    j.Release
End Sub

then load into :

Dim img As B4XBitmap = xui.LoadBitmap(File.DirAssets, "temp.png")
Dim xIV As B4XView = ImageViewCircularImage
xIV.SetBitmap(CreateRoundBitmap(img, xIV .Width))

So.. i think it's must be download image then save images, then we load it into imageview to make circle?
Corret Me if i'm wrong...
thank's...

For example in this picture with the red block...
Can I immediately make a circle without saving the image like I was doing before ?

Yes. Use Job.GetBitmap.

Place an ImageView inside a Panel. Set Panel background drawable to circle shape. Load image to ImageView it will automatically clip the image.
