PHP :: Request #66516 :: getimagesize() should cater to orientation flag

[2014-01-19 16:01 UTC] milpas999 at gmail dot com

Description:
------------
My objective is to upload an image and then to create a new image with some other 'width X height' resizing parameters. Original image has uploaded successfully, but when i am using getimagesize('local path of original uploaded image') it is returning wrong values.

And this function is not working only for images of dimension '1836 X 3264' 

original image dimension : 1836 X 3264
and when using getimagesize() for the image it returns

Array
(
    [0] => 3264
    [1] => 1836
    [2] => 2
    [3] => width="3264" height="1836"
    [bits] => 8
    [channels] => 3
    [mime] => image/jpeg
)

Same as  Bug #29424. but i am unsing PHP 5.4.3 and bug reporter was using PHP 5.0.0

Test script:
---------------
$source_image_path = '../sysimages/origimage/20131109_151445.jpg';

$arrrrr = getimagesize($source_image_path);

print("<pre>arrrrr :: ");
print_r($arrrrr);
print("</pre>");

Expected result:
----------------
Array
(
    [0] => 1836
    [1] => 3264
    [2] => 2
    [3] => width="1836" height="3264"
    [bits] => 8
    [channels] => 3
    [mime] => image/jpeg
)

Actual result:
--------------
Array
(
    [0] => 3264
    [1] => 1836
    [2] => 2
    [3] => width="3264" height="1836"
    [bits] => 8
    [channels] => 3
    [mime] => image/jpeg
)

Please provide a link to the image you use.

There is certainly a rotation/orientation meta data which makes some application automatically rotate the image on load.

I have the same issue with PHP 5.4.12.

It looks to mainly happen with pictures taken with a smartphone.


Here is the picture: https://drive.google.com/file/d/0B2PDHMmm8JwMbkVESkU5STZtVjA/view?usp=sharing

Note that this picture has been resampled.

Here is the original one:

I tried with it, and I get inverted width and height value too.

What @pajoye said is correct: the image itself is sideways but the camera added EXIF data that specifies the "correct" orientation. GIMP, for one, presents a dialog to that effect when you try to open the file.
Since getimagesize() is behaving the way it was intended to, I'm changing this to a feature request.

If it returned the re-oriented dimensions then that could cause problems if code relies on them while trying to process the image. Maybe it could continue returning the true dimensions but also include a new value in the array indicating the orientation?

However the exif extension is also available to handle this kind of problem. See some of the user comments in the exif_read_data() doc for examples:
http://php.net/exif-read-data#usernotes

Ok, I understand now.
It makes sense.

So if my picture has exif data, I will rely on them, otherwise, I will take the getimagesize result as it is.

Thank you for your quick reply.
