My images

Command

magick mogrify -resize x600 *.jpg

result

What version of IM, on what platform? It seems to work fine on v7.0.7-27 on Windows 8.1:

Code: Select all

f:\web\im>%IMG7%magick -size 2322x4128 xc: -resize x600 info:

xc: XC 338x600 338x600+0+0 16-bit sRGB 2.906u 0:00.562

last version 7.0.8-11 on Windows 10

but I can not specify the height that there are several folders with different sizes

Post one of the images that fail

This command works fine for me on IM 7.0.8.11 Q16 Mac OSX.

Code: Select all

magick mogrify -resize x600 temp.jpg

Here you have the images to prove what happens

https://mega.nz/#!tl41WJgD!FR9jPsfDD4K7 ... u-wAVeuM_Q

I tested all your images using Imagemagick 7.0.8.11 Q16 Mac OSX Sierra with

Code: Select all

magick mogrify -resize x600 -format jpg -path ../images2 *

All your landscape format images ended up with height = 600. The two portrait image ended up with width = 600.

This is the same whether I use IM 6.9.10.11 or simply magick or convert rather than mogrify.

Is this not what you get?

It is unclear to me if there is a bug or not depending upon what was meant at https://imagemagick.org/script/command- ... p#geometry for xheight. But I would have interpreted that such that portrait mode images also should end up with a height of 600 and the width adjusted to preserve the aspect.

I suspect that your issue is the way your file explorer shows the file information due to exif information. The following happens with a resize:

I can't download and work my way through a 20 MB rar. Perhaps the "portrait" format images are so only because they have that orientation metadata, and IM sees them as "landscape".

Dirk,

I get your same values. But Mac Preview shows two portrait mode images with width=600.

I think the issue is that there is EXIF orientation information for lgeqsv2v.jpg which is RightTop. It looks like Imagemagick identify is reading the file size without reoriented and my Mac PREVIEW is reorienting it. That may be why identify shows all files as height 600, but PREVIEW shows the ones that get reoriented to portrait as width=600.

So if I do

Code: Select all

convert -auto-orient * info:
b3skpyik.jpg[0] JPEG 1067x600 1067x600+0+0 8-bit sRGB 0.000u 0:00.039

vphupvfs.jpg[9] JPEG 1067x600 1067x600+0+0 8-bit sRGB 0.010u 0:00.029

Now two images show width=600.

Note that IM 7 fails to allow the -auto-orient.

Code: Select all

magick -auto-orient * info:

magick: no images found for operation `-auto-orient' at CLI arg 1 @ error/operation.c/CLIOption/5251.

This would seem to be an oversight bug.

That's not a bug. V7 doesn't allow image operations before reading images. So this works fine:

Code: Select all

magick *.jpg -auto-orient info:

My misunderstanding. I thought it was a setting that had to be before reading the image. Thanks

Thanks to all!! I already found the solution

I used

Code: Select all

magick mogrify -auto-orient -resize x600 *.jpg

and it worked

Code: Select all
