AUTOMATIC ATTACHMENT ROTATION (AND RESIZE) v6.11
By Dougiefresh -> Link to Mod


Introduction
This mod allows the automatic rotation and/or flipping of images ONLY IF the EXIF information contained within (if such exists) indicates that such processing is required in order to show the picture in the correct orientation.

IMPORTANT NOTE FORM SMF 2.0: In order to fully support the Post and PM Inline Attachments mod you must install this mod after you install that mod!!
Also, if you subsequently need to uninstall the Post and PM Inline Attachments mod you must uninstall this mod first.

NOTE: SMF contains an option called Re-encode potentially dangerous image attachments, which is enabled by default.  This re-encoding removes the orientation information from attachments (amongst other things), which means attachments uploaded prior to this mod being installed will NOT be able to rotated properly, as the EXIF information is missing from the re-encoded attachment file!!

Major changes introduced in v6.10
o Support for SMF 2.1 RC4 (official release only - not GitHub releases).
o Support for ImageMagick/Imagick image processor.
o Added options for rotating images and thumbnails separately when modifying a message (and for Admins when browsing files via the Admin center).
o Added code to display a thumbnail-sized copy of each attached image (and a smaller version of the real thumbnail if it exists) when editing a message (and for Admins when browsing files via the Admin center).

Major change introduced in v6.00
o - Support for SMF 2.0.18 and PHP 7.4.

Major change introduced in v5.0
o Option to automatically, manually or batch resize/reformat existing images using 'Attachment Settings' options (non-JPEG images will only be reformatted to JPEG if the Reformat non-JPEG images to JPEG option is enabled).

Major changes introduced in v4.0
o Option to enable/disable automatic image rotation.
o Code update to enable automatic image resizing/reformatting in posts (and PMs if the PM Attachments mod is installed).

Post Screen Changes
Beside each image attachment a dropbox will be displayed listing the following rotation options for the Image/Thumbnail, Image Only and Thumbnail Only:
o No Change
o Rotate 90o Right
o Rotate 90o Left
o Rotate 180o
o Horizontal Flip
o Vertical Flip
o Horizontal Flip, Rotate 90o Right
o Vertical Flip, Rotate 90o Right

Automatic Resizing of Existing Images
When a post is displayed, and if the Attachment Setting Resize existing images option is enabled, images in the post will be automatically resized (and reformatted to JPEG if the Attachment Setting option Reformat non-JPEG images to JPEG is enabled) using the same Attachment Setting options (ie, Reformat non-JPEG images to JPEG, JPEG quality factor and/or maximum width/height) that are applied to new image attachments in posts.  In addition, if the Attachment Setting option Create backup of original image file when resizing is also enabled the original image file will be saved to the attachments directory with the extension '.rei'.
Note: Images posted by members who belong to a membergroup that has specific JPEG quality and/or maximum width/height values configured will be resized according to the values configured for that membergroup.

Manual Resizing of Existing Images
This feature, which can be accessed via Admin => Forum => Attachments and Avatars => Browse Files => Resize Existing Images, can be used to selectively resize/reformat existing images using the same Attachment Setting options (ie, Reformat non-JPEG images to JPEG, JPEG quality factor and/or maximum width/height) that are applied to new image attachments in posts.
Note: Images posted by members who belong to a membergroup that has specific JPEG quality and/or maximum width/height values configured will be resized according to the default configured values.

Batch Resizing of Existing Images
This feature, which can be accessed via Admin => Forum => Attachments and Avatars => File Maintenance => Batch Resize Existing Images, will resize/reformat all existing images using the same Attachment Setting options (ie, Reformat non-JPEG images to JPEG, JPEG quality factor and/or maximum width/height) that are applied to new image attachments in posts.
Note: Images posted by members who belong to a membergroup that has specific JPEG quality and/or maximum width/height values configured will be resized according to the default configured values.

The forum should be configured as follows prior to commencing batch resizing:
o Admin => Configuration => Server Settings => General => Enable Maintenance Mode should be enabled.
o Admin => Configuration => Security and Moderation => General => Disable administration security should be disabled.
o Admin => Forum => Posts and Topics => Topic Settings => Number of posts per page in a topic page should be configured to between 15 and 25 via (make a note of the current value).
o Admin => Forum => Attachments and Avatars => Attachment Settings - Maximum size per attachment, Reformat non-JPEG images to JPEG, JPEG quality factor, Maximum width of attached images and Maximum height of attached images should be configured.
o Admin => Forum => Attachments and Avatars => File Maintenance => Attachment Integrity Check should be run and issues corrected.

Important notes for batch resizing:
o Non-JPEG images will only be reformatted to JPEG if the Reformat non-JPEG images to JPEG option is enabled.
o Existing 'attachments' database table will be copied to 'attachmentsPreREI' database table. *
o Original image files are saved to the 'attachmentsPreREI' directory/folder. *
o File timestamp for resized image file is set to match timestamp of original image file.
o Batch processing progress information is displayed and updated.
o The results of the batch resizing process will be displayed on completion and also written to the forum error log file.

* The 'attachmentsPreREI' database table and directory/folder can be removed after checks have been done to confirm successful resizing - this will free up additional disk space on the server.

The forum should be configured as follows after batch resizing has finished:
o Admin => Configuration => Security and Moderation => General => Disable administration security should be enabled.
o Admin => Configuration => Server Settings => General => Enable Maintenance Mode should be disabled.
o Admin => Forum => Posts and Topics => Topic Settings => Number of posts per page in a topic page should be configured to previous value.

Admin Changes
In Admin => Forum => Attachments and Avatars:
o Browse Files: There is a new column (and associated button) for rotating/flipping images - the options for rotating/flipping images are only shown for image attachments.  There is also a new horizontal tab labelled 'Resize Existing Images' that can be used for manually resizing/reformatting existing images.
o Attachment Settings: Options to enable/disable the mod, configure a specific memory limit for image rotation/resizing, configure automatic image rotation and automatic resizing of existing images, enable/disable reformatting/resizing, option to reformat non-JPEG images to JPEG and options to set JPEG quality factor and max width/height values for attached images.  Also option to configure different JPEG quality factor and max width/height values for some membergroups and to enable/disable this feature.
- **File Maintenance**: There is a new section for *Batch Resize Existing Images*.  There is also a new section for *Reset Orientation Flag*.
o File Maintenance: There is a new section for Batch Resize Existing Images.  There is also a new section for Reset Orientation Flag.

o Improved Attachment Error Handling

For SMF 2.0 - The following mod must be uninstalled before installing this mod:

Special Credit
This mod relies on the phpExifRW class, which is licensed under the GNU Lesser General Public License, in order to read the EXIF information from image files.  This class makes the requirement of having EXIF support built-in, which some servers do not have, not important to the task of successfully pulling the orientation out of the image file.  The exifReader.inc file was renamed to Class-exifReader.php in order to name the file in accordance with the naming convention of SMF and included in this mod.

Test images with EXIF orientation values embedded in them are available at Galloway.me.uk, at the Image Orientation thread over at the ElkArte forum, and on GitHub - Recurser.
