Tests imports

Only used for testing

>>> import os
>>> from Products.Archetypes.tests.utils import mkDummyInContext
>>> from Products.Archetypes.tests.utils import Dummy
>>> from Products.Archetypes.atapi import *

This one must be imported in the type’s module

>>> from collective.croppingimagefield import fields as cif

Sample schema definition

>>> schema = BaseSchema + Schema((
...     cif.CroppingImageField('image',
...         original_size=    (800,600,
...                            cif.RESIZE_CROP),
...         sizes={'mini' :   (80,80), # default : scale (AT original behavior)
...                'normal' : (200,200,
...                            cif.RESIZE_SCALE),
...                'big' :    (300,300,
...                            cif.RESIZE_ZOOM),
...                'maxi' :   (500,500),
...                'header' : (500,150,
...                            cif.RESIZE_CROP)}),
... ))

Setting up testing datas

Creating a dummy object using the schema

>>> instance = mkDummyInContext(
...     Dummy, oid='dummy',
...     context=self.portal,
...     schema=schema)

Check that the image has been correctly loaded in the test case

>>> self._image[:5]
'GIF89'

Set the image and check that it has been stored in the image field

>>> instance.setImage(self._image, mimetype='image/gif')
>>> instance.getImage()
<Image ...>

Image scales

image is 800x600 (cropped so not 600x600)

>>> instance.image.width, instance.image.height
(800, 600)

There is an image_mini scale

>>> instance.image_mini
<Image ...>

It is 80x60 (Default (SCALE)image is resized to fit in the rectangle)

>>> instance.image_mini.width, instance.image_mini.height
(80, 60)

There is an image_normal scale

>>> instance.image_normal
<Image ...>

It is 200x150 (SCALEimage is resized to fit in the rectangle)

>>> instance.image_normal.width, instance.image_normal.height
(200, 150)

There is an image_big scale

>>> instance.image_big
<Image ...>

It is 300x300 (SCALEimage is resized so the smallest side fit in the rectangle, and image overflow is kept)

>>> instance.image_big.width, instance.image_big.height
(400, 300)

There is an image_header scale

>>> instance.image_header
<Image ...>

It is 500x150 (SCALEimage is resized so the smallest side fit in the rectangle, and image overflow is cropped)

>>> instance.image_header.width, instance.image_header.height
(500, 150)
