Description

Using this syntax:

class ThumbnailImage(EmbeddedDocument):
    element = ImageField(size=(200, 250, True), thumbnail_size=(50, 60, True))

What I would like is the ability to re-size the image to a maximum of 250px high and set the thumbnail size to maximum 60pixels high but for the re-sizing that occurs to maintain the aspect ratio.

Thoughts?

Research direction

Start by locating the ImageField handling for the size and thumbnail_size options. Check how resizing currently interprets those dimensions, then define tests using images with differing aspect ratios to verify maximum heights and preserved proportions.
