Plage de couleur Pixel contigu

[kimlicrea]

Bonjour,

Lorsque que j'utilise la plage de couleur , pour supprimer une couleur, il me supprime , la couleur avec une valeur alpha partilement en fonction de la proximité de la couleur repère.

J'aimerai qu'il supprime à 100% les pixel , comme peut le faire baguette magique lorsque la case pixel contigu est déchoché

merci

The fuzziness slider is supposed to be like the Threshold setting in the Magic Wand, but like it's counterpart, it's difficult to determine the setting that will get what you want. Instead, use the eyedroppers to add to your original selection, or delete from it. So, select one color - then drag around your additional colors using the eyedroppers (OR, use the Shift to add to selection, or Option to delete from the selection). You can even use the tools inside the Preview window.
Avoid touching colors that are close to those outside what you want, or you may select way too much. Use Eyedropper to Add to Selection with Select>Color Range

Hi,

Either I misunderstood, or that's not what I'm asking.

I would like to know how to transform a "Color range" selection with contiguous pixels into a selection without contiguous pixels.
This is for print on mirror, and i need net value, color pixel or not print

not possible?

You must use the eye droppers in the color range dialog box to add them to your selection. Did you watch the video?  Color Range selects all of the same color in an image - doesn't matter if they are contiguous or not. Honestly, it's a crap tool. Maybe post a screenshot of what you are trying to achieve and we can give you some suggestions?

In fact if it matters, I would like to use the color range tool without contiguous pixels, or transform the selection into pixels without alpha value afterwards.

If the pixels have an alpha between 1 and 99 when printing, the print on a mirror has trouble behaving. I would like the vlauer to be either full or absent

Okay - now I understand...
The Select Color Range too is not intended to work as you request. It really is about selecting contiguous colors, and there's no good way to make absolute selections - UNLESS the original colors are very distinctly different, in which case, Melissa's suggestion above will work.
