I´m not sure so I understand your question....

I use the commands from anthony viewtopic.php?f=1&t=18337#p70354 with a small adaption...

I crop from a big image (original image) a smaller square image (extract image) with a offset to x and y.

I crop this image to a triangle from top-left-corner -> top-right-corner -> upper-right-corner and return.

This triangle come to "field 1" viewtopic.php?f=1&t=18337&start=15#p73850

mirror this to field 2

mirror square field to 3+4 or 7+8

mirror a last one...

have the extract image e.g. 647x647px so have the result image the double width and height (1294x1294px)

thats all...

then what is the question or problem? why do you say your result is not correct? can you make a correct result in python? if so, then provide an example image from python and one from IM command line to show us the difference.

see my note above. but you can try swapping the black and white as you reversed it from what Anthony's example had.

convert \( -define jpeg:size=646.875x646.875 -depth 8 test2_orig.jpg -extract 646.875x646.875+17.1875+301.5625 \) \
\( -clone 0 -transpose \) \
\( -clone 0 -sparse-color voronoi "%w,0 black 0, %h white" \) \
\( -clone 0 -clone 1 -clone 2 -compose Src -composite -rotate 180 \) \
\( -clone 3 -flop -chop 1x0 \) \
-delete 0-2 +append \
\( +clone -flip -chop 0x1 \) -append \
caleidoscope_test2_orig.jpg.png

try

convert \( -define jpeg:size=646.875x646.875 -depth 8 test2_orig.jpg -extract 646.875x646.875+17.1875+301.5625 \) \
\( -clone 0 -transpose \) \
\( -clone 0 -sparse-color voronoi "%w,0 white 0, %h black" \) \
\( -clone 0 -clone 1 -clone 2 -compose Src -composite -rotate 180 \) \
\( -clone 3 -flop -chop 1x0 \) \
-delete 0-2 +append \
\( +clone -flip -chop 0x1 \) -append \
caleidoscope_test2_orig.jpg.png

Does that help?

Also try without the -rotate 180?

What a pity...

your command is not the soution - the result looks like a "patchwork", is to big and have black stripes

Her come the the commands like "anthony-version" from the Python thats bring a corret result:
you can test this with http://www.e-spin.de/privat/test2_orig.jpg and look at the result in viewtopic.php?f=1&t=18337&start=15#p73872

I test the first row

convert \( -define jpeg:size=646.875x646.875 -depth 8 test2_orig.jpg -extract 646.875x646.875+17.1875+301.5625 \) extract-test.png

=> extract-test.png is the same as test2_orig.jpg ??

Using zelda3.png for testing, I get exactly the same thing from your commands and mine as follows:

yours:


infile="zelda3.png"
convert $infile -sparse-color voronoi "%w,0 black 0, %h white" zelda3_mask.png
convert $infile \( +clone -transpose \) zelda3_mask.png -compose Src -composite zelda3_mirror.png
convert zelda3_mirror.png -rotate 180 zelda3_rotate.png
convert zelda3_rotate.png \( +clone -flop -chop 1x0 \) +append \( +clone -flip -chop 0x1 \) -append zelda3_caleidoscope.png




Mine:

infile="zelda3.png"
convert $infile \
\( +clone -transpose \) \
\( +clone -sparse-color voronoi "%w,0 black 0, %h white" \) \
-composite -rotate 180 \
\( +clone -flop \) +append \
\( +clone -flip \) -append \
zelda3_kaleidoscope_180.png



P.S. Why are your images ending in both .jpg.png


This reproduces your result with your image:


convert \( -size 646.875x646.875 -depth 8 -extract 646.875x646.875+17.1875+301.5625 test2_orig.jpg \) \
\( +clone -transpose \) \
\( +clone -sparse-color voronoi "%w,0 black 0, %h white" \) \
-composite -rotate 180 \
\( +clone -flop \) +append \
\( +clone -flip \) -append \

Wow - this works fine!!!!!!

I dont understand why my picture have 1293x1293px an your command produce 1294x1294px...

I shold round the values to integer 646.875 => 647...

the ".jpg.png" extension is a small "bug" at my python script

Thank you very mutch!!!!!!!!!!!!!!!!!!! for your help - I wish, I can revanche to you...

Based upon all this testing and Anthony's concept, I have embellished it and made a new script, kaleidoscopic, at the link below. Note this is totally different from my kaleidoscope script.
