Re: [Gimp-user] Does Gimp support more than 8 bits per color channel?

["Joao S. O. Bueno" <gwidion mpc com br>]

more bits per pixels on the monitor/graphics card are actual
independent of what your image editing software supports.

8bits per color component is more than you eye can distinguish
already, so if these 10 bit components cost extra, don't go for them.

Contrast is another thing: you should aim for good monitor contrast
,where black is black.

So, detailing the display parts: I don't know if x11 or Wayland
support 10bpp for display use. Anyway, GIMP uses GTK2 + Cairo for
doing the interface, and those sure are 8bpp only.

GIMP 2.9 however can manipulate images with comparatively arbitrary
color depths (32bits per color, or 32bit floating point). That will
just work on "regular" 8bpp hardware, and the extra depth, while
making difference in several situations in an image manipulation
pipeline, does not translate to direct physical "view" depth in any
device> the extra depth is good when transforming lightness conditions
in parts of the image and preserve a smooth local color gradient.

So, again: this 10bpp of monitors and video boards have nothing to do
with GIMP's ability of manipulating 32bit float per component, and it
does not make the least difference.
