IM7: subimage specification returns no images

Hi there,
this has worked for years in IM6, I've changed
montage to
magick montage for IM7:
Code: Select all
magick montage "02_%04d.png[1-63]" -tile 9x7 -geometry 256x256+0+0 test.png
But now I'm getting tons of these:
Code: Select all
magick: subimage specification returns no images `02_0030.png' @ error/constitute.c/ReadImage/637.
magick: invalid image index `02_0031.png' @ error/list.c/CloneImages/281.
magick: subimage specification returns no images `02_0031.png' @ error/constitute.c/ReadImage/637.
magick: invalid image index `02_0032.png' @ error/list.c/CloneImages/281.
magick: subimage specification returns no images `02_0032.png' @ error/constitute.c/ReadImage/637.
magick: TooManyExceptions (exception processing is suspended) @ warning/exception.c/ThrowException/978.
magick: invalid image index `02_0033.png' @ error/list.c/CloneImages/281.
Of course, the files are existing and valid,
identify doesn't show any problems.
my build is:
Code: Select all
Version: ImageMagick 7.0.8-25 Q8 x64 2019-01-28 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2018 ImageMagick Studio LLC

Visual C++: 180040629
Features: Cipher DPC Modules OpenMP
Delegates (built-in): bzlib cairo flif freetype gslib heic jng jp2 jpeg lcms lqr lzma openexr pangocairo png ps raw rsvg tiff webp xml zlib
Seems like a bug to me
Best regards,

Are you sure you have 64 images? If so, the indices should be [0-63] if you want all of them. Seems like it is not finding anything starting and following [32]. What is your OS?
This works for me on IM 7.0.8.25 Q16 Mac OSX Sierra
Code: Select all
magick rose: rose_00.png
magick rose: rose_01.png
magick rose: rose_02.png
magick rose: rose_03.png
magick montage "rose_%02d.png[0-3]" -tile 2x2 -geometry +2+2 result.png

No, more than 64. That's why I'm not using an asterisk for globbing.

No, it starts at "..._0001.png"

Verified, this works.
Ahhh, have a look!
Code: Select all
# delete rose_00.png
magick rose: rose_01.png
magick rose: rose_02.png
magick rose: rose_03.png
magick rose: rose_04.png
magick montage "rose_%02d.png[1-4]" -tile 2x2 -geometry +2+2 result.png
Tadaa:
Code: Select all
montage: invalid image index `rose_01.png' @ error/list.c/CloneImages/281.
montage: subimage specification returns no images `rose_01.png' @ error/constitute.c/ReadImage/637.
montage: invalid image index `rose_02.png' @ error/list.c/CloneImages/281.
montage: subimage specification returns no images `rose_02.png' @ error/constitute.c/ReadImage/637.
montage: invalid image index `rose_03.png' @ error/list.c/CloneImages/281.

Agreed. If it starts with [0, it works fine even if it does not go to the last index. But if it starts with any other index, it fails.
This works:
Code: Select all
magick rose: rose_00.png
magick rose: rose_01.png
magick rose: rose_02.png
convert rose: rose_03.png
magick montage "rose_%02d.png[0-1]" -tile 2x1 -geometry +2+2 result.png
This fails:
Code: Select all
magick rose: rose_00.png
magick rose: rose_01.png
magick rose: rose_02.png
convert rose: rose_03.png
magick montage "rose_%02d.png[1-2]" -tile 2x1 -geometry +2+2 result.png
Tested with IM 7.0.8.25 Q16 Mac OSX
