[b4x][XUI] Imageslider ios blurry image tweak / tip

I have been using image slider and I noticed that the images on iOS were a bit blurred.

​

I tried using the tip here https://www.b4x.com/android/forum/t...ed-if-the-image-scale-down.100068/post-629511, but this resulted in images that were too large and still blurred.

​

It seems that the code within ImageSlider needs a bit of a tweak as well.

The tweak is to update the code inside the imageslider class.

Change the following line in ShowImage from

    NextPanel.GetView(0).SetLayoutAnimated(0, WindowBase.Width / 2 - bmp.Width / 2, _
        WindowBase.Height / 2 - bmp.Height / 2, bmp.Width, bmp.Height)

to

    NextPanel.GetView(0).SetLayoutAnimated(0, Max(0,WindowBase.Width / 2 - bmp.Width / 2), _
        Max(0,WindowBase.Height / 2 - bmp.Height / 2), _
         Min(WindowBase.Width,bmp.Width), Min(WindowBase.Height,bmp.Height))

and you will get nice sharp images !

​

NOTE: the GetImage Callback needs to be changed as well.

Sub isImages_GetImage (Index As Int) As ResumableSub

    Private myFile As String = $"splash${NumberFormat(Index + 1,1,0)}.png"$
   ' scale image for non blurry rendering on iOS
    Dim scale As Float
    #if B4a or B4j
      scale = 1
    #else if B4i
     scale = GetDeviceLayoutValues.NonnormalizedScale
   #end if
    Return xui.LoadBitmapResize(File.DirAssets,myFile , isimages.WindowBase.Width*scale, isimages.WindowBase.Height*scale, True)
End Sub
