How to detect orentation of an image inan action
|

| I want to write an action that works on and can detect if the image is
landscape or portrait.
The Break down is
If portrait then set the image height to 400px
If portrait then set the image width to 400px
Set the canvas size = 410 X 410
Then there is other processing to be done…
The rest I can do no Problems

Assuming you meant "If landscape" for the last one...
File->Automate->Fit Image... and set each dimension to 400px.
> Set the canvas size = 410 X 410
Image->Canvas Size... - you may need to set the canvas extension background
colour.

Hmm... for me, I just avoid rotating "portrait"-oriented pictures.
That way, all my pictures are always oriented in the same direction in
Photoshop and all my actions just work.
If I'm printing, it never matters anyway. If I want it for web
viewing, I can always rotate the portrait-oriented ones myself as a
final step (e.g., put all of them in a separate folder and have an
action that rotates all of the images in that folder and outputs to a
new folder).

| If you are talking about Dig. camera images... I have been thinking about this
too - what is REALLY required is for the camera software to write a bit to the
EXIF information for each file. This bit ought to be 0 if the camera is held in
landscape mode and 1 if in portrait mode, for example.
To ascertain which is which - I would suggest a simple tilt device in the
camera body which could detect the rotation angle - in fact a more complex
piece of kit could tell exactly what angle the camera is being held at and then
that information oughtt to go in the Files EXIF info..
The Application software would of course then have to read this data from the
EXIF information to determine whether the image was portrait or landscape.
This would save an awful lot of tilting ones head when viewing images on a TV
screen, for instance, where image rotation may not be available...
Would help in other ways too of course..
Just a thought!!

This is nothing new, many cameras already utilize this. Many software suites
also use this.

Almost every modern digital camera has this option already, and in fact,
that is exactly why the OP has his problem. Because the images are
rotated already, he needs to use 'Fit Image' to resize them because
there are portrait and landscape images.

| Are you saying some digital cameras' embedded software writes a status word to
the files exif information so that application software can tell whether its a
portrait or landscape image? If so - which cameras and what is the status word/bit?

My Canon digitals have always had this ability. They use a sensor in the
camera to detect which way is up (I understand it's a small metal ball
in a curved tube)and my downloading software - Breeze Systems Downloader
Pro - can orient the picture correctly. Don't ask me which EXIF bit it
is, though. I'm a photographer, not a programmer :)

Yep, that's what I'm saying. Not 'some' cameras, almost every modern
camera has this ability. Perhaps the very cheap ones don't, but the rest
do. It's not a word, it's two bits in the EXIF data. The first bit tells
if an image should be rotated or not. The second bit tells in which
direction (+90° or -90°).

Thanks for that information - I have fuji Digital cameras - 6500 and S7000
(and an ld 4900) - I will take a look - though I don't appear ever have been
given the option when opening a file is PS (or PSP), of rotating an image..
Maybe PS does not have this functionality (I have PS7)
cheers

Hi - thanks for the offer - but I looked in the EXIF information for 3 images
from the 3 different cameras - there is nothing in there I can see
Cheers

I just checked 4 cameras, all have the orientation sensor and this shows on
the exif data. Whether or not software uses it is another matter.

Seems a little wasteful to me. With 2 bits of info they could have 0,+/-90,=
_and_ 180 degrees (just in case you were=20
holding the camera upside-down).

Except that I don't think that the orientation sensor records that...

| Hi again
Ok - thanks for that link - will take a look.
Another poster suggested this isn't what the orientation sensor records, if
not, what IS it?
