Image content type for Kotti

Kotti

Kotti is a high-level, Pythonic web application framework based on Pyramid and SQLAlchemy. It includes an extensible Content Management System called the Kotti CMS (see below).

Kotti is most useful when you are developing applications that

• have complex security requirements,
• use workflows, and/or
• work with hierarchical data.

Built on top of a number of best-of-breed software components, most notably Pyramid and SQLAlchemy, Kotti introduces only a few concepts of its own, thus hopefully keeping the learning curve flat for the developer.

Kotti CMS

Kotti CMS is a content management system that's heavily inspired by Plone. Its main features are:

• User-friendliness: editors can edit content where it appears; thus the edit interface is contextual and intuitive
• WYSIWYG editor: includes a rich text editor
• Responsive design: Kotti builds on Bootstrap, which looks good both on desktop and mobile
• Templating: you can extend the CMS with your own look & feel with almost no programming required
• Add-ons: install a variety of add-ons and customize them as well as many aspects of the built-in CMS by use of an INI configuration file
• Security: the advanced user and permissions management is intuitive and scales to fit the requirements of large organizations
• Internationalized: the user interface is fully translatable, Unicode is used everywhere to store data

kotti_image's Issues

Images where not scaled correctly

Adding custom scales results in incorrectly scaled images when the scales where used.
The scaling function scaleImage/scalePILImage in plone.scale (used in version 2.1.1) knows 3 keywords . Up, down, thumbnail.

However, the function scaleImage from the image view called with the keyword thumb which results in incorrectly scaled images where parts are cropped. I assume it resizes and crops as if the keyword down was given.

Stack trace for image view

When calling
http://127.0.0.1:5000/about/someimage/image/span3
http://127.0.0.1:5000/about/someimage/image
but not:
http://127.0.0.1:5000/about/someimage/image/span3/download

I get a stack trace on the command line below. In the browser the image is rendered OK.
