Hi,
Is there a way to select all pixels in an image that are below
certain color value, even if they are not adjacent?
Basically, I have an image that I display in an outside program. Black
is the color key (displays as transparent), becuase the image contains
some very dark colors that are not really black (for example R=5, G =
0, B = 5 and so on), they appear as black, whilst I want them not to
appear at all.
Is there a way to select all those seemingly dark pixels (even if they
are not adjacent) so that I can turn them to black?
Thank you very much in advance
Adjust threshold and pick similar colours (Shift+O). When selected,
press Ctrl+, (control plus comma) to replace selected areas' color to
foreground one (black by default)
or
Layer>Colors>Level... choose top left eye-dropper („Pick black point“)
and choose brightest region you want to appear black.
