Image field for ``Archetypes`` with different behavior at time of scaling.
============
Introduction
============
Archtypes default ``ImageField`` scales down the image until the whole image
fits into the given scale. It keeps it aspect ratio. I.e. scaling down a 400x300
image to a 200x200 scale result in a 200x150 image.
Same with ``ClippingImageField`` results in a 200x200 image! It centers the
image horizontal or vertical and tries to keep as much as possible from the
original.
Tested with Plone 3.3.x and Plone 4.
======
Usage:
======
Field
=====
Specify the sizes as documented for the classic Archetypes ImageField. If you
want specific scales to get clipped, add a field-property
``crop_scales=['image_large','other_scale']``. It expects a list of scale
names to include into clipping.
Patch
=====
By including ``patch.zcml`` in your package ``archetypes.clippingimage`` will
patch ``Products.Archetypes.Field.ImageField`` so it is able to generate
cropped scales.
You can define which scales shall be cropped by adding a property ``crop_scales``
to your ImageField::
ImageField('image',
sizes= {'large' : (768, 768),
'preview' : (400, 400),
'listing' : (16, 16),
},
crop_scales = ['listing'],
...
Note that if you want to use clipped images within ATCTImage and have
``plone.app.imaging`` installed you need to set a property ``crop_scales`` at
``plone.app.blob.subtypes.image.SchemaExtender.fields[0]``.
Blob
====
In case of using the patch everythings fine. No further action needed. If you
use the field, you need to include the ``blob.zcml`` to make the fields scales
blobs.

Changelog
=========
2.1
===
- use the format of original image for computing the crop. the field
used to convert everything to png which resulted in relatively large files
[fRiSi]
2.0
===
- make plone.app.imaging and plone.app.blob aware. Works now with Plone 4.
[jensens]
- sizes can be a callable or a dictionary (instance method not supported)
background: plone.app.imaging uses the sizes defined in imaging_properties in case sizes is a dictionary.
so you need to define sizes via a callable to make your custom sizes take effect.
[fRiSi]
- added monkeypatch for ImageField.scale to add croppingsupport to any ImageField
