Can't rotate image. Ver 2.1.11

[bbfriend]

I can't rotate image.

Ver 2.1.11

http://...../elfinder/elfinder.html , all defaut Setting.(Nothing has been set) upload image ･･ OK resize ,crop , rename ･･ OK

But can't rotate. example ,rote_tab -> rotate 90 -> Click Apply I get message to Error Unable to connect to backend "Invalid backend response. Data is not JSON."

What do configuration and operating conditions I need? Github Demo http://studio-42.github.io/elFinder/ is rotate OK.

~~*addition) now I checked by Firebug. "NetworkError: 500 Internal Server Error - http://..../elfinder/php/connector.minimal.php?cmd=resize&target=l1_MTIyLmpwZw&width=228&height=328&degree=90&quality=100&mode=rotate&_=1462804481335~~

@bbfriend Have you more infomation about php errors from server log?

[ghost]

@nao-pon on this subject, what PHP libraries need to be installed to allow image resizing, rotating, and so on with the editing options?

[nao-pon]

@bbfriend I fixed notice error in rotate function @b98d582b785fb4211e6f0b1a79025dda37adcebc.But it was Notice error, It may not be the cause of this problem

[nao-pon]

@StudioJunkyard elFinder use php imagick extention, GD, or server command convert(imagimagick). And rotate function use server command exiftran or jpegtran if it is possible.

Ah ok, I've stayed away from imagick as there's currently an open security issue with it (might be patched now), that was posted about in /r/netsec in Reddit. I've got GD2 installed on the live server, but the edit, for resize and rotate isn't working according to client reports, I haven't had time to test it myself. Is there something that needs to be enabled in the connector settings, or elsewhere?

[nao-pon]

@StudioJunkyard Use GD(2) to image libs with connector root config 'imgLib' => 'gd'.

Thanks @nao-pon, much appreciated. Client's have been loving using your project in my CMS, it's made things so much easier. Using it as an addon for Summernote WYSIWYG editor, and as a Media Manager embedded in a page.

@nao-pon　私は、日本人です。　Error message was different. エラーを間違ってました。 ”Invalid backend response. Data is not JSON.”　 and Firebug does not have an error.

*Apache/2.2.15 CentOS 6.2 libjpeg-turbo.x86_64 1.2.1-3.el6_5 php-gd.x86_64 5.3.3-46.el6_7.1

And ,Strange phenomenon? elfinder.html changes in PHP execution form.

Apache Module

Apache CGI ,FastCGI

[bbfriend]

Oh! Find! elFinderVolumeDriver.class.php　About line4495 Line4460

protected function imgRotate($path, $degree, $bgcolor = '#ffffff', $destformat = null, $jpgQuality = null) {  
    debug($path, $degree);  
    if (($s = @getimagesize($path)) == false || $degree % 360 === 0) {

to

protected function imgRotate($path, $degree, $bgcolor = '#ffffff', $destformat = null, $jpgQuality = null) {  
//    debug($path, $degree); 
    if (($s = @getimagesize($path)) == false || $degree % 360 === 0) {

Comment out debug($path, $degree);

”rotate image”　work fine! Thanks for the tip.@nao-pon

[ghost]

For me it was at line 4460.

[ghost]

Actually, for me the radio buttons are disabled.

[bbfriend]

Hi! @StudioJunkyard. you're right. Line 4460.

[nao-pon]

@bbfriend @StudioJunkyard This bug was already fixed in master branch. Please check with nightly build.

Thanks!

[ghost]

Cheers @nao-pon keep up the great work.

I just update everything, even cleared my browser cache to be sure the updated code is being used. I can resize image, but the crop and rotate radio buttons are still disabled. Is there maybe some setting I need to enabled, or apache/PHP library that needs to be installed?

[ghost]

Actually, I just noticed all three radio buttons are disabled. But the resize still works.

[ghost]

I should check things a bit more closely. When I actually go to perform the resize on an image, I get back a dialog with an error: Invalid parameters for command "resize".

I'm going to publish as a plugin CMSimple,stable(regular) version is required. ありがとう。

[nao-pon]

@StudioJunkyard Perhaps ... It seems there are problems in the JavaScript or theme side. Please create a new issue, if necessary.

[nao-pon]

@bbfriend OK. 2.1.12 coming soon.

@nao-pon, currently client's just upload a thumbnail image they wish to use, as I use elF in three ways. As a plugin to Summernote for media management, as a file uploader and selector within an input field for main and thumbnail images for products, blog cover images, and as a stand alone media manager on it's own page. It would be handy to for client's to edit a single upload image by duplicating it, renaming it, and cropping or rotating to use a thumbnail.
