Oh thank you!
-sample and -scale are faster, much more faster

Quality is good enough i think too!

Ok with this it works. But resizing is still very slow.
And it would be nice if i could do this in one command/Batch script!


convert 7296.jpg \
\( +clone -resize 100% -write thumb_1.jpg +delete \) \
\( +clone -resize 75% -write thumb_2.jpg +delete \) \
\( +clone -resize 50% -write thumb_3.jpg ...

convert 7296.jpg -crop 1024x1024 -set filename:tile "%[fx:page.y/1024]_%[fx:page.x/1024]" 0_%[filename:tile].jpg

Original.jpg = 7296x5472px

First row:
0_1.jpg
0 ...
