GIMP tools - BDA

We already know the first three options (Mode, Antialiasing, Feather edges) from the
Rectangular Select Tool.
The Select transparent areas option offers you the ability to select areas that are
completely transparent.
The Sample merged option becomes relevant only when you have several layers in your
image: the active layer that is either semi-transparent or fully transparent. The colours
present in the active layer will be different from the colours in the composite image. If
this option is unchecked, the Fuzzy Select Tool will react to the colours in all the possible
layers.
The slider of the Threshold scale determines the range of colours that will be selected at
the moment you click on the initial point. The lowest value is 0, the highest value – 255,
the default value – 9.1. If you enter a low value, the points, the colour of which is the
same as the point you clicked on, will be selected. Increasing the value expands the
selection area by connecting the points with a larger range of colours.
a) Threshold = 2 b) Threshold = 5
In the Select by drop-down list you can choose how to select colours.
Select by Color Tool
The tool above selects the image areas based on the colour similarity, while
selects the areas that are in the chosen range of colours. It has the same options as the
Fuzzy Select Tool.
