Bitmap.GetPixel color format

I cannot understand what is the format of GetPixel. I get Int color -16745317 , what does it mean ? Thanks

It's a 32 bit number which represents the byte values of the Alpha, Red, Green and Blue components of the colour. You can deconstruct it with

Sub GetARGB(Color As Int) As Int()
    Dim res(4) As Int
    res(0) = Bit.UnsignedShiftRight(Bit.And(Color, 0xff000000), 24)
    res(1) = Bit.UnsignedShiftRight(Bit.And(Color, 0xff0000), 16)
    res(2) = Bit.UnsignedShiftRight(Bit.And(Color, 0xff00), 8)
    res(3) = Bit.And(Color, 0xff)
    Return res
End Sub

and construct it from the components with the keyword ARGB(Alpha As int, R As int, G As int, B As int) As int.

Hi agraham,

How can one gets the color of a table cell in a scrollview?

Thanks

A table cell in a ScrollView is a Label.
So you need to get the Label view and get its color with the code you find here Get Color(of a label).
Are you filling the table ?
If yes, you should know the color you give the cell.
If you are using the Table class, you can get the colors with
- getRowColor1 for the odd rows
- getRowColor2 for the even rows
- getSelectedRowColor for a selected row
