G'MIC fun with afre

Joan_Rake1 · November 27, 2018, 10:30pm

Edit: it turned out that my earlier implementation was faster on my machine, not sure why. I’m using 2.4.1. Here’s what I’ve built around that:

#@gui 8-Bit planes : fx_bitplane8, fx_bitplane8_preview(1)
#@gui : Mode = choice("Decompose","Recompose")
#@gui : Split mode = choice("Z layers","Separate images")
#@gui : Scale mode = choice("True","1","255")
fx_bitplane8 :
if $1
##recompose
if {!$2} s z fi
repeat {int($!/8)} l[$>-{$>+7}]
repeat 8
iter=$>
l[$>]
if {$3==0}
/ {2^$iter} cut 0,1 round 0,1 * {2^$iter}
elif {$3==1}
cut 0,1 round 0,1 * {2^$iter}
elif {$3==2}
/ 255 cut 0,1 round 0,1 * {2^$iter}
fi
endl done
+
endl done
else
##decompose
repeat 8
[0]
&[-1] {2^$>} 
if {$3==1}
/[-1] {2^$>}
elif {$3==2}
/[-1] {2^$>/255}
fi
if {!$2} a[^0] z fi
done
rm[0]
fi
#n 0,255
fx_bitplane8_preview :
fx_bitplane8 $*

Whatever works for you. As I said before, I prefer simple and elegant, short and sweet.

I admit that it’s a bit of a mess but it seems to work exactly as I feel it should:

An option to keep true values, set values to either 0 or 1 or set them to either 0 or 255
Repeats on every 8 slices, doesn’t do anything else
Rounds values for idiotproofing (but being G’MIC code, it’s easily-hackable).
Options to keep 8 separate images or merge them along the Z axis

Given that in hindsight some of my commands have very questionable design choices (like that extra ‘recompute’ option which the commands require as arguments despite it only having a use to easily refresh any randomising things through the GUI without resetting parameters), I suppose I’ll need to redesign some of the commands I’ve made.

I was having some G’MIC fun yesterday and came up with something interesting. See post #307 of G’MIC exercises for more info. As usual, it is just something that I stumbled upon and so might not be compelling to you.

More edge fun.

It seems interesting to say for the least. Is there a color version? I found out about that I could replicate PS Emboss to a extent though I’m not back with G’MIC as you know why.

That’s emboss toward 3 channel on high depth image.

More fun. This time with a broken afre_dehaze.

Just having fun, officer. Messing with the transmission. A few broken car windows here and there.

That never worked for me, but it looks like corrupted segments or something. @Joan_Rake1 could describe that better since she’s the resident glitch expert.

Fun with afre_cleantext.

With multiplication.

Result looks like a hybrid of photorealism and manga or pen art.

Vote for the ones you like. I apologize for the low quality GIF.

I would like to have the lc series, they look rather interesting.

More fftfun!

Fg1 series are better in my opinion.

EDIT: Actually, can’t decide here.

Joan_Rake1 · June 12, 2019, 11:07pm

I’d love to have the lot with some extra parameters for each.

afre_fft* make good animations (which could benefit from an ease-in speed curve but G’MIC doesn’t have those fine controls from ImageMagick).

Power

Too much power

… Power tends to corrupt, and absolute power corrupts absolutely. Great men are almost always bad men, even when they exercise influence and not authority, still more when you superadd the tendency or the certainty of corruption by authority. …
