Media rotating, cropping, resizing etc in 2.9.

[JohnMyr]

Im not sure if its appropriate to post this ticket, but I didnt find any tickets for media rotation, cropping etc.

Adding some basic editing functions like 90-degree rotation, cropping and resizing was considered an obvious winner in the dev chat, and as several plugins handle this functionality, we’re hopeful it will be included soon.

I propose including of the Scissors plugin by Stephan Reiter:
​http://wordpress.org/extend/plugins/scissors/

Its matured and well tested and has nice usability features and uses jQuery.

You changed the component, So the owner changed. Dont worry about it.

I believe Andrew was going to be working on this feature.

The challenge here is that imagerotate() is "...only available if PHP is compiled with the bundled version of the GD library". There are replacement functions but they are very slow especially for large images as they copy the source image pixel by pixel.

Perhaps we can do image rotation only when the function is available. Image flip can be done with imagecopyresampled() (the same function used for resizing) and cropping with Jcrop.

Image rotation is also available through another commonly-provided/easily-installed suite, ImageMagick. There is already a php class that is extremely simple to use and can be substituted in case the GD imagerotate is unavailable. See ​http://us2.php.net/manual/en/function.imagick-rotateimage.php for details. I think it would be nice to fall back on the imagick version of rotation and whatever else imagick supports that can't be accomplished without a bundled GD library, rather than leaving such functions unavailable. ImageMagick can be easier to install in cases where the bundled GD library is not readily available as a package.

Yes, was looking at ImageMagick too. It seems less web hosts offer it and generally it's available in addition to GD. Still the proper way would probably be to check for imagerotate and Imagick, then disable rotation if neither is present. Will also need to compare them (less server resources, better quality, faster).

Plugin that implements an image editor - GUI needs work, code needs to be intergrated into WP code

First run in [11911].

This is far from ready, still need to separate the image meta in at least 3 different rows and implement some way to delete unneeded backup images. Also have to add support for ImageMagick when GD rotate is not available and auto-rotation of the uploaded image when EXIF orientation is set.

-1, core bloat.

Sorry, but I do not understand sentence "Previously edited copies of the image will not be deleted." When I restore original image then all changes are deleted ("Discard any changes and restore the original image."), I guess.
