EXIF orientation bug

[peugas]

The last available binary version 6.3.1 doesnt recognise
canon orientation EXIF, so i cannot use auto-orient or
even orient options:

EXAMPLE
- with jhead:
Exif header 10238 bytes long
Exif section in Intel order
(dir has 9 entries)
Make = "Canon"
Model = "Canon PowerShot S80"
Orientation = 6
XResolution = 180/1
YResolution = 180/1
ResolutionUnit = 2
DateTime = "2006:10:24 12:04:45"
YCbCrPositioning = 1
ExifOffset = 196
Exif Dir:(dir has 31 entries)

Which ImageMagick binary are you using. We tried your image with the latest ImageMagick release, 6.3.1-7 and got this:

But have you tried auto orient to correct the right orientation of the image?

I am using the latest window binary, and i have tried with different images (orientation) and it cannot be detected! the orientation is always zero (irfanview and others correctly detect the orientation

for the same image:
Make: Canon
Model: Canon PowerShot S80
Orientation: 0

that should be (with jhead / www.sentex.net/~mwandel/jhead)
Make = "Canon"
Model = "Canon PowerShot S80"
Orientation = 1

[magick]

Post a URL to one or two images where you think ImageMagick is not properly reading the orientation parameter. Let us know what ImageMagick reports and what you think it should be. We'll try to reproduce the problem and come up with a fix.

[peugas]

The two small files cannot be resized with mogrify or they loose the orientation exif information (must be rotated 90º clockwise)

PS:convert and mogrify cannot read the orientation exif tag properly

After rotation with irfanview (automatically)

Thanks for your help

Try ImageMagick 6.3.2-1. It reports the correct EXIF orientation.

ok now it is working correctly
