[Archetypes-users] plone.app.blob image sizes

[Andreas S. <and...@xh...>]

Hi!

I've run into trouble using the ImageField of plone.app.blob. It seems that
it does not support image sizes, or at least I cannot access it via an URL
in the browser. I'm using following code (incomplete snippet):

from plone.app.blob.field import ImageField as BlobImageField

MyTypeSchema = folder.ATFolderSchema.copy() + atapi.Schema((

    BlobImageField(
        'myimage',
        languageIndependent=True,
        storage=atapi.AttributeStorage(),
        widget=atapi.ImageWidget(
            label=_(u"Image"),
        ),
        sizes={
            'icon'     : (32,32),
            'mini'     : (64,64),
            'small'    : (128,128),
            'preview'  : (256,256),
            'medium'   : (512,512),
            'banner'   : (1024,1024),
            'original' : (1024,1024),
        },
        original_size=(1024,1024),
        pil_quality=90,
        required=True,
        validators=('isNonEmptyFile'),
    ),

))

Proof me wrong, but shouldn't I be able to access the image via an URL like
http://localhost/mysite/mytype/myimage_preview. Is this really not
supported by the blobstorage product, or am I missing something important?
