Image direct pasting feature

[tigergm]

Please consider the feature of direct paste for image from clipboard. Thanks. Great plugin.

Hello.

First of all, thank you very much for providing the software for GPL free. I appreciate that very much. Thx.

I'm running redmine 3.3 and also would like to have direct copy from clipboard. The problem: It works in the editor (I can copy an image from clipboard, can save it, edit the text field again with the image present), but it's not shown on the rendered text. 'img' and 'src' are included in ckeditor.yml

Is it possible at all? Is it an issue with core redmine or with the plugin or with other plugins? Maybe redmine has a tag filter for img with base64 encodes images. The img tag and the 'alt' attribute is present but not 'src' attribute.

Hello, ulrichmueller. It is not easy to paste directly in the editor in rm on account of the image which can't be upload to the image server. Your image pasted is only shown on the web client instead of the server. But there must be solutions for it such as the ckeditor's plugins and ckfinder which is commercial unfortunately. I know the redmine_ckeditor uses the rich_fille gem which need a lot of effort to fulfil the image-direct-past.

I tried to use ckeditor plugin to implement the feature... but not successful. Anyone could tried how to config it?

the plugin is upload image, it contains paste the image from clipboard with ckeditor in 4.5.X or higher version. http://ckeditor.com/addon/uploadimage

Thanks.

Hi @archonwang,

I'm almost there: I needed to add a few other plugin to have uploadimage working: uploadwidget, widget, notificationaggregator, lineutils, widgetselection, filetools.

I updated CKeditor to 4.7.0 following these instructions https://github.com/a-ono/redmine_ckeditor#upgrading-ckeditor-for-development

The problem now is that I need to configure uploadUrl. We can set this variable in a ckeditor.yml placed in REDMINE_ROOT/config.

I tried /uploads and /rich/files but I get errors in both cases.

Completed 422 Unprocessable Entity in the first case and ActionView::Template::Error (undefined method signin_path'inlib/redmine/menu_manager.rb:192`

I also see a Can't verify CSRF token authenticity in both cases.

If anyone can help !

Hi

Nobody has the solution ?

I just tried to install the uploadimage ckeditor plugin in the plugins\redmi‌​ne_ckeditor\assets\c‌​keditor-contrib\plug‌​ins folder but it breaks ckeditor (all icons gone)

Moreover I uste Redmine 3.4.3 and ckeditor redmine plugin 1.1.5.

Thanks

The plugin uploadimage need server side program to work, CKFinder is provided for such purpose.

I found that @xiaoli provide Ruby solution at project: https://github.com/xiaoli/redmine_ckeditor And it works very well.

I just upgrade it to CKEditor 4.13.1 and upload to my repo: https://github.com/Henry586/redmine_ckeditor

Now list key parts of image upload:

1. the well know ckeditor plugin uploadimage; http://ckeditor.com/addon/uploadimage
2. server side ruby; https://github.com/xiaoli/redmine_ckeditor/blob/master/app/controllers/ckeditor_controller.rb
3. ckeditor config.js like below: config.uploadUrl = '/ckeditor/upload'; refer: https://github.com/Henry586/redmine_ckeditor/blob/master/assets/ckeditor/config.js

All in all, you can get my Repo and run it immediately!

And please also note that ONLY one image should be pasted once a time in Chrome. Multiple image paste are supported by Firefox.

The default content length is 64KB, so you can only save small image file with Base64 format, but no limitation if image is uploaded to server.

There is a solution to this problem! 🚀 Base64 will solve the problem.

Add to file /plugins/redmine_ckeditor/init.rb:

Loofah::HTML5::WhiteList::ALLOWED_PROTOCOLS.replace RedmineCkeditor.allowed_protocols
Loofah::HTML5::WhiteList::ALLOWED_PROTOCOLS.add('data')

This is necessary to display images with a base64 data type.

Then add https://ckeditor.com/cke4/addon/pastebase64 to /plugins/redmine_ckeditor/assets/ckeditor-contrib with all plugin dependencies and restart redmine.

It works flawlessly! 🤩

Works perfectly!

[tazus]

I used pastebase64 it work great!! However, I got a problem that the function only shown in Wiki's editor but not issue/task editing area. Anyone know what's wrong?
I used 3.49 with ckeditor plugin for Redminehttp://github.com/a-ono/redmine_ckeditor | Akihiro Ono | 1.1.7。 And followed, https://www.redmine.org/boards/2/topics/58357 to install pastebase64,base64image to ckeditor plugins.

my redmine/plugins/redmine_ckeditor/assets/ckeditor/config.js is

CKEDITOR.editorConfig = function( config ) {

    config.extraPlugins = 'pastebase64,base64image';

};

and plugins/redmine_ckeditor/init.rb as:

require 'redmine' require 'redmine_ckeditor'

Rails.application.config.to_prepare do RedmineCkeditor.apply_patch end

Redmine::Plugin.register :redmine_ckeditor do name 'Redmine CKEditor plugin' author 'Akihiro Ono' description 'This is a CKEditor plugin for Redmine' version '1.1.7' requires_redmine :version_or_higher => '3.0.0' url 'http://github.com/a-ono/redmine_ckeditor'

settings(:partial => 'settings/ckeditor')

wiki_format_provider 'CKEditor', RedmineCkeditor::WikiFormatting::Formatter, RedmineCkeditor::WikiFormatting::Helper end

Loofah::HTML5::WhiteList::ALLOWED_PROTOCOLS.replace RedmineCkeditor.allowed_protocols Loofah::HTML5::WhiteList::ALLOWED_PROTOCOLS.add('data')

[adrianobr]

Do you need add the plugins: 'pastebase64' and 'base64image' In config.js add: config.extraPlugins = 'pastebase64'; config.extraPlugins = 'base64image';

And init.rb add: (Loofah::VERSION >= "2.3.0" ? Loofah::HTML5::SafeList : Loofah::HTML5::WhiteList)::ALLOWED_PROTOCOLS.add('data')

Working perfect!

Pasting images directly works @ my end - simply by adding data protocol to the allowed protocols in the config file, without additional plugins or anything: REDMINE_ROOT/config/ckeditor.yml

this is after copying the config sample as per the instructions in the readme: cp plugins/redmine_ckeditor/config/ckeditor.yml.example config/ckeditor.yml

Then simply add data to allowed protocols:

allowedProtocols:
  - data
  - afs
  - aim
  - callto

@a-ono Maybe this could be added to the readme?
