B4A Library [B4X] [XUI] AS Tab Menu - sizing of icons

in the following example code from the main thread, where does the 30 (size of rendered font bitmap) comes from?
B4X: 
ASTabMenu_horizontal.AddTab(xui.Color_ARGB(255,39, 174, 97),"",ASTabMenu_horizontal.FontToBitmap(Chr(0xF015),False,30,xui.Color_White),"")
height in the layout are expressed in dip, while for fonts are not
how do you make sure your icon is at the correct size, on different density displays?

because this was the perfect size on my device. The finished image is adjusted to the size of the imageview anyway.

here is the function:

Unlike an older "TextToBitmap" sub that you can find in the forum, this code vertically centers the icon. It can also be used in B4J and B4i (only need to change the font line). Sub Activity_Create(FirstTime As Boolean) 'usage example Activity.AddMenuItem3("Android", "Test"...

FontToBitmap looks blurry

When I use FontToBitmap the text or icon looks blurry, in B4A it doesn't, there is a way to improve the sharpness and change the size (I see it a bit small) https://www.b4x.com/android/forum/threads/fontawesome-to-bitmap.95155/#post-603250
www.b4x.com

B4X: 
Sub SetBitmapDensity(b As Bitmap) As Bitmap
    Dim jo As JavaObject = b
    Dim den As Int = Density * 160
    jo.RunMethod("setDensity", Array(den))
    Return b
End Sub
