How to read transparency level ?

[GauSte]

Hello,
I open a picture with several shapes with several transparency colours.

I would like to pick the colour and the transparency level.
If I use the colour picker tool, I can read the RGB levels for the color, but I can't find the transparency level.

Where can I find it for this pixel ?

Thanks

Use the "Pointer" dialog, it tells you everything about the pixel under the pointer (whatever the active tool):

   

Tells you RGB, alpha, actual pixel data (useful when in "Linear" mode) for the active layer or the whole image (with Sample merged).

In the same vein you also have the "Sample points" dialog.
