-------------------

- ZON-3363: Some UI/form field tweaks for infographics.

- ZON-3363: Hide thumbnails in content listing of ``ImageGroup``.

- Be defensive about zero-sized images.


2.17.0 (2016-09-28)
-------------------

- Deprecate automatic image link rewriting (VIV-263)

- Add nofollow flag to image links (ZON-3375)


2.16.3 (2016-09-26)
-------------------

2.16.2 (2016-09-12)
-------------------

- Handle non-ASCII uniqueIds in ``variant_url``.


2.16.1 (2016-09-05)
-------------------

- Be defensive about falling back to image metadata.


2.16.0 (2016-08-18)
-------------------

- Proxy image reference attribute access to its target and ignore
  copied metadata (unless, of cause the attribute is overriden locally).
  We still copy the XML on creation and update for compatibility. (Re ZON-1586)


2.15.1 (2016-08-11)
-------------------

- Have master_image_for_viewport() fall back on "the largest image" it
  can find if a nonexistent name is configured.


2.15.0 (2016-08-10)
-------------------

- Add ``IImageGroup.master_image_for_viewport()``.

- Determine ratio for "original" Variant from the actual source image
  during transform, so it is viewport-sensitive. This also means
  ``Variant.ratio`` for "original" is now None instead of a float,
  since at that point we do not have the viewport information.


2.14.4 (2016-08-04)
-------------------

- Bugfix: actually create thumbnail source when an imagegroup is added.


2.14.3 (2016-08-02)
-------------------

- Be defensive about invalid master image properties.


2.14.2 (2016-08-02)
-------------------

2.14.1 (2016-08-01)
-------------------

- Pass IImageMetadata of synthesized images through to the image group.


2.14.0 (2016-07-26)
-------------------

- Be defensive about zoom=0 settings.

- Allow viewport modifier inside URL of image variants. (ZON-3171)

- Store multiple master images and which viewport they should be used for,
  rather allowing a single master image for everything. (ZON-3171)

- Render variants using the master image for given viewport. (ZON-3171)

- Remove dependency to `zeit.imp`. (ZON-3171)

- Adjust image templates to preview them more similar to Friedbert. (ZON-3216)


2.13.5 (2016-06-27)
-------------------

- Be defensive about imagegroups with no master image.

- Be defensive about zero-sized images.


2.13.4 (2016-05-03)
-------------------

- Be defensive about invalid variant requests.


2.13.3 (2016-04-25)
-------------------

- Allow materialized images with legacy names to serve as source for
  size and fill color transformation. (ZON-2029)

- Apply maximum image size only for the requested size, not the size
  of the source/master image.


2.13.2 (2016-04-18)
-------------------

- Don't load Zope/UI specific ZCML in the model ZCML


2.13.1 (2016-04-18)
-------------------

- Set a maximum image size to protect against overload


2.13.0 (2016-04-07)
-------------------

- Deprecate image spoof protection signature (ZON-2878).

  ``cinema__100x200__0000ff`` (ZON-2878).
  * Add parameter ``fill_color`` to ``variant_url()``
  * Add property ``IImages.fill_color``


2.12.0 (2016-02-29)
-------------------

- Deprecate image alignment setting (ZON-2782).


2.11.8 (2016-02-25)
-------------------

  extension (BUG-357).


2.11.7 (2016-02-22)
-------------------

- Move ``MemoryFile`` to zeit.cms.


2.11.6 (2015-11-17)
-------------------

- Be more defensive about missing meta files when creating variant images.


2.11.5 (2015-10-30)
-------------------

- Use `libmagic` instead of hand-coded zope.app.file heuristics, it supports
  a wider range of mimetypes (e.g. ico which z.c.cp uses for rss feeds).


2.11.4 (2015-10-30)
-------------------

- Use simple heuristic instead of PIL.image.open to determine mime-type
  (since reading PSD files with PIL has been seen to hang indefinitely).


2.11.3 (2015-10-29)
-------------------

  ``nofollow`` set).

  original images to legacy clients (which don't know to ask for a specific,
  smaller size). (ZON-2236)


2.10.1 (2015-09-17)
-------------------

- Clean up temporary image blob files on abort as well as commit. (ZON-2237)


2.10.0 (2015-09-12)
-------------------

- Use variant image of `default` configuration as master image in frontend to
  preview image enhancements while ignoring cropping due to zoom. (DEV-826)

- Add UI and backend support to adjust variant images regarding their
  brightness, contrast, saturation and sharpness. (DEV-826)

- Disable transparency of variant previews when displaying the master (DEV-910)

- Increase the size of cropper handles, to make it easier to grab the edge of
  the canvas to resize a variant. (DEV-910)

- Automatically switch back to the master image, when the background of the
  variant editor was clicked. (DEV-910)

- Show that the focuspoint can be dragged by changing cursor to grab. (DEV-910)


2.9.0 (2015-09-08)
------------------

- Add ``fallback_size`` setting for variants, also available as
  ``fallback_width`` and ``fallback_height`` (ZON-2145).

  missing from the XML config and are only present in the DAVProperty (DEV-910)

------------------

------------------

- Variants UI Styling updates by jpfn.


2.6.0 (2015-07-30)
------------------

- Ignore invalid image size specifications. (ZON-1586)

- Adjust variants and groups to friedbert's needs, e.g. limit default sizes
    to largest max_size, always produce a master_image, configure pillow
    encoder settings. (ZON-1586)


2.5.2 (2015-07-06)
------------------

- Set zoom and focuspoint of Variant sizes using a rectangular UI. (DEV-827)


2.5.1 (2015-06-23)
------------------

- Change name of thumbnail traverser so it does not conflict with the
  ``thumbnail`` view used by zeit.find.

------------------

- Add bw-compat for CP editor: return old on-disk variants for new syntax
  (DEV-783).

  * New product config setting ``zeit.content.image:variant-secret``. If given,
    variant URLs are generated and require a signature (to prevent URL
    spoofing).

- Resize (and reposition if target size has a different ratio than the variant)
  the generated variant image according to the target size parameter in the URL
  (DEV-796).

- Support bw-compat mapping of old cropped image names to variants (DEV-783).
  * New config file: ``/data/image-variants-legacy.xml``, for
    ``zeit.content.image:legacy-variant-source``

- Read attributes for ``z.c.image.variant.Variant`` from XML using it's schema
  rather relying on manual type conversion. (DEV-786)

- Generate thumbnail images (for variants editor, cp editor etc.) from a
  smaller image instead of the master image for better performance (DEV-797).

------------------

- Introduce new cropping UI with focus points (UI has feature toggle
  ``zeit.content.image.variants``) (DEV-779).
  * New config file: ``/data/image-variants.xml``, for ``zeit.content.image:
    variant-source``

- Add validation rules for ImageGroup to check on publish that important
  image sizes were created. (DEV-790).

------------------

- Display original caption in reference details (VIV-365).

- Rewrite links from www.zeit.de to xml.zeit.de (VIV-263).
  NOTE: This functionality is still disabled, since the frontend
  does not interpret rewritten links correctly yet.
