MuK Thumbnails |
|||
============== |
|||
|
|||
Technical module to provide some utility features and libraries that can be used |
|||
in other applications. This module has no direct effect on the running system. |
|||
|
|||
Requirements |
|||
============= |
|||
|
|||
Unoconv |
|||
------------- |
|||
|
|||
Universal Office Converter (unoconv) is a command line tool to convert any |
|||
document format that LibreOffice can import to any document format that |
|||
LibreOffice can export. It makes use of the LibreOffice's UNO bindings for |
|||
non-interactive conversion of documents. |
|||
|
|||
To install unoconv please follow the instructions (`here <https://github.com/dagwieers/unoconv>`_). |
|||
|
|||
Make sure that unoconv can be executed from the console and the conversion |
|||
is done correctly. |
|||
|
|||
To set an individual path for the LibreOffice installation, the config |
|||
variable ``uno_path`` can be set accordingly in the Odoo config. |
|||
|
|||
Under Windows you should rename the ``unoconv`` file to ``unoconv.py`` and set |
|||
the corresponding path for the ``uno_path`` variable. Since it does not work |
|||
reliably with the environment variable ``UNO_PATH``. |
|||
|
|||
FFmpeg |
|||
------------- |
|||
|
|||
FFmpeg is a complete, cross-platform solution to record, convert and stream audio and video. |
|||
|
|||
To install FFmpeg please follow the instructions (`here <https://www.ffmpeg.org/download.html>`_). |
|||
|
|||
Ghostscript |
|||
------------- |
|||
|
|||
Ghostscript is a suite of software based on an interpreter for Adobe Systems PostScript and |
|||
Portable Document Format (PDF) page description languages. Its main purposes are the |
|||
rasterization or rendering of such page description language files, for the display or printing |
|||
of document pages, and the conversion between PostScript and PDF files. |
|||
|
|||
To install Ghostscript please follow the instructions (`here <https://www.ghostscript.com/download.html>`_). |
|||
|
|||
ImageMagick |
|||
------------- |
|||
|
|||
ImageMagick can be used to create, edit, compose, or convert bitmap images. It can read and write |
|||
images in a variety of formats (over 200) including PNG, JPEG, GIF, HEIC, TIFF, DPX, EXR, WebP, |
|||
Postscript, PDF, and SVG. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and |
|||
transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, |
|||
ellipses and Bezier curves. |
|||
|
|||
To install ImageMagick please follow the instructions (`here <https://www.imagemagick.org/script/download.php>`_). |
|||
|
|||
Wand |
|||
------------- |
|||
|
|||
Wand is a ctypes-based simple ImageMagick binding for Python. It is used to interact with ImageMagick via a Python interface. |
|||
|
|||
To install Wand please follow the instructions (`here <http://docs.wand-py.org/en/0.4.1/guide/install.html>`_). |
|||
|
|||
Imageio |
|||
------------- |
|||
|
|||
Imageio is a Python library that provides an easy interface to read and write a wide range of image data, including animated images, volumetric data, and scientific formats. |
|||
|
|||
To install Imageio please follow the instructions (`here <https://pypi.org/project/imageio/>`_). |
|||
|
|||
MoviePy |
|||
------------- |
|||
|
|||
MoviePy is a Python module for video editing, which can be used for basic operations (like cuts, concatenations, title insertions), video compositing (a.k.a. non-linear editing), video processing, or to create advanced effects. It can read and write the most common video formats, including GIF. |
|||
|
|||
To install MoviePy please follow the instructions (`here <https://zulko.github.io/moviepy/install.html>`_). |
|||
|
|||
Installation |
|||
============ |
|||
|
|||
To install this module, you need to: |
|||
|
|||
Download the module and add it to your Odoo addons folder. Afterward, log on to |
|||
your Odoo server and go to the Apps menu. Trigger the debug mode and update the |
|||
list by clicking on the "Update Apps List" link. Now install the module by |
|||
clicking on the install button. |
|||
|
|||
Another way to install this module is via the package management for Python |
|||
(`PyPI <https://pypi.org/project/pip/>`_). |
|||
|
|||
To install our modules using the package manager make sure |
|||
`odoo-autodiscover <https://pypi.org/project/odoo-autodiscover/>`_ is installed |
|||
correctly. Then open a console and install the module by entering the following |
|||
command: |
|||
|
|||
``pip install --extra-index-url https://nexus.mukit.at/repository/odoo/simple <module>`` |
|||
|
|||
The module name consists of the Odoo version and the module name, where |
|||
underscores are replaced by a dash. |
|||
|
|||
**Module:** |
|||
|
|||
``odoo<version>-addon-<module_name>`` |
|||
|
|||
**Example:** |
|||
|
|||
``sudo -H pip3 install --extra-index-url https://nexus.mukit.at/repository/odoo/simple odoo11-addon-muk-utils`` |
|||
|
|||
Once the installation has been successfully completed, the app is already in the |
|||
correct folder. Log on to your Odoo server and go to the Apps menu. Trigger the |
|||
debug mode and update the list by clicking on the "Update Apps List" link. Now |
|||
install the module by clicking on the install button. |
|||
|
|||
The biggest advantage of this variant is that you can now also update the app |
|||
using the "pip" command. To do this, enter the following command in your console: |
|||
|
|||
``pip install --upgrade --extra-index-url https://nexus.mukit.at/repository/odoo/simple <module>`` |
|||
|
|||
When the process is finished, restart your server and update the application in |
|||
Odoo. The steps are the same as for the installation only the button has changed |
|||
from "Install" to "Upgrade". |
|||
|
|||
You can also view available Apps directly in our `repository <https://nexus.mukit.at/#browse/browse:odoo>`_ |
|||
and find a more detailed installation guide on our `website <https://mukit.at/page/open-source>`_. |
|||
|
|||
For modules licensed under OPL-1, you will receive access data when you purchase |
|||
the module. If the modules were not purchased directly from |
|||
`MuK IT <https://www.mukit.at/>`_ please contact our support (support@mukit.at) |
|||
with a confirmation of purchase to receive the corresponding access data. |
|||
|
|||

|||
and log on to your Odoo server. Select the Apps menu and upgrade the module by |
|||
clicking on the upgrade button. |
|||
|
|||
If you installed the module using the "pip" command, you can also update the |
|||
module in the same way. Just type the following command into the console: |
|||
|
|||
``pip install --upgrade --extra-index-url https://nexus.mukit.at/repository/odoo/simple <module>`` |
