ResizeImageField

(extension of RemovableImageField) =================================

by Wim Feijen, Go2People.

What does it do?

ResizeImageField is a replacement for django's ImageField. It has two major benefits: 1. Creation of thumbnails and scaled images. 1. Extends the image upload form and adds a preview and a checkbox to remove the existing image.

It's easy to use: - Replace ImageField by ResizeImageField - No further changes are necessary

Requirements:

Working installation of PIL, the Python Imaging Library

Usage

• add resize_image to your app
• add resize_filters.py to your templatetags
• in settings.py, set a PHOTO_DIR, f.e. photos/original
• in models.py, add:
  • from settings import PHOTO_DIR
  • from resize_image import ResizeImageField
  • photo = ResizeImageField(upload_to=PHOTO_DIR, blank=True)

Scaled images will be stored in 'photos/scaled', thumbnails will be stored in 'photos/thumb'.

Access your images from your template. Add:

{% load resize_filters %} 
{{ address.photo.url|thumb }} 

or:

{{ address.photo.url|scaled }} 

Defaults -------- Scaled images are max. 200x200 pixels by default - Thumbnails are 50x50 pixels.

Override the default behaviour in settings.py

Scaling is done by PIL's thumbnail function, transparency is conserved.
