Ah yes it works! Thanks!

Thanks for the reply. No luck with that:


$ convert MSVG:mvg_circles2.mvg mvg_image.gif
convert: Document is empty
`No such file or directory` @ error/svg.c/SVGError/2919.
convert: no images defined `mvg_image.gif' @ error/convert.c/ConvertImageCommand/3275.



$ ls -l mvg*

Thanks! Maybe I'll try building when I'm feeling especially brave...

I'm trying to reproduce the third example in this section under Reading MVG Files:

https://www.imagemagick.org/Usage/draw/#reading


The example shows this .mvg file contents:

Is there a build time switch or setting for enabling integral images then? I don't normally tackle building IM but I could give it a shot. Running a beta OS (macOS Mojave) at the moment so I could have some problems but I could try.

Haven't looked at the new links yet but looking forward to that ...

Thanks!

Also I am going to chew on that other technique you documented in that web page. Integral images. Looks promising but the challenge for me will be to boil it down to a script that returns a single comparable value (or maybe it's not hard... haven't tackled the whole page yet, it looks a bit past my ...

Running on some test images:


$ cd blurry/
sagaraga :blurry$ for n in *.jpg; do magick $n -statistic StandardDeviation 15x15 -format %[fx:maxima] info:; echo ""; done
0.360601
0.374182
0.385077
0.347387
0.302251
sagaraga :blurry$ cd ../non_blurry/
sagaraga :non_blurry$ for n in *.jpg; do magick $n ...

Oh I see what it was; I had an extra space before "maxima".

Wow yes it is slow! But a great thing to start with, thanks!

Wow that is a very nice web page! Great work.

Thanks for the reply. I'm trying it out, with some hiccups so far.

Tried your command and got this:


magick: unable to open image 'maxima]': No such file or directory @ error/blob.c/OpenBlob/3457.


Playing around with quotes around the format ...

I'm working with photo data and need to split the images into two sets: focused and unfocused.

Without getting into complications like depth of field where images can have some regions focused and others non-focused... just keeping it simple and assuming the entire image is unfocused due to either ...

That parens trick is new to me. Very useful, thanks. And -geometry versus -size always confused me. I'll get it one of these days!

Also btw it seems stuff still works on my system without the magick preface, but I take it things are heading that direction so I'll start updating scripts to use that.

Thanks! That works great for me too.

EDIT: Platform macOS

I'd like to use the montage command to create a single image where each panel has its own different text label.

I'm more familiar with the -draw "text.." command than the -label command, but I dismissed the -label command as ...
