Took the image from yesterday and applied a bevel. I’m liking that!
Here are the settings. Highlight colour is #999.
That’s after a couple blurs and thresholds.
50 Wing Pairs #
Alright, I generated a bunch of wings that I can use to document this project.
Now some ImageMagick to switch them to black on white, since that’ll look better on the website.
mogrify -negate output/*
And another to generate a montage.
montage output/wing_*.png -background DimGrey -tile 5x -geometry +2+2 output/montage.png
Problem with my montage is that some of the similar wings are right next to each other. I’d like to shuffle the images first.
shuf to the rescue!
montage `ls output/wing_*.png | shuf` -background DimGrey -tile 5x -geometry +2+2 output/montage.png ; open output/montage.png
And since the resulting image is huge:
convert -resize 1080 output/montage.png output/montage1080.png
Unforch the wings don’t show up that well at such a small scale. Hrm.
Blur and threshold to widen the lines.
Nope, there’s a better way. -morphology Dilate Octagon
That gives me this transformation:
And the resulting montage looks muuuch much better.
Got the above effect using:
convert wing_001.png -emboss a.png
convert a.png wing_001.png -alpha Off -compose CopyOpacity -composite amasked.png
That does an emboss effect and then masks it so the background isn’t grey.
The lines look really angular and jagged. Not as good as the first image in this post, I don’t think. Maybe I should blur and threshold?
Here’s another version using -shade instead of -emboss
convert wing_001.png -shade 45x45 a.png
Is that actually exactly the same?
