"auto-orient" + "flatten"

[doublemax]

Testcase (result should be 'landscape'):

Code: Select all

wget https://raw.githubusercontent.com/recurser/exif-orientation-examples/master/Landscape_5.jpg
/usr/local/bin/convert -auto-orient "Landscape_5.jpg" -flatten "result.png"

Other examples from this list work fine.
ImageMagick 6.9.2-7

Thanks!

Are the good images and bad images from the same camera etc. Different cameras can write different data to the image or none at all.

Have you checked the image data with -identify -verbose?

What happens without the -flatten?

[fmw42]

try putting -auto-orient after the input image.

Same, orientation-flag-example is wrong:

Code: Select all

wget https://raw.githubusercontent.com/recurser/exif-orientation-examples/master/Landscape_5.jpg
/usr/local/bin/convert "Landscape_5.jpg" -auto-orient -flatten "result.png"

From this list all the images work but the "5s" and the "7s":

Thanks a lot

Why do you need the -flatten? It works perfectly without that extra unnecessary option.

[doublemax]

Input images are user-uploaded image files.
They can have layers - and I want a generic commandline (any uploaded image should become a PNG/JPG image)

[dlemstra]

Adding +repage after -auto-orient seems to resolve the issue.

You are right - sorry for disturbing.
