Checks if file uploaded through file input was saved in one of selected image formats and has dimensions (width and height) within given boundaries. Does *not* check for maximum file size (use IS_LENGTH for that). Returns validation failure if no data was uploaded. Supported file formats: BMP, GIF, JPEG, PNG. Code parts taken from http://mail.python.org/pipermail/python-list/2007-June/617126.html Args: extensions: iterable containing allowed *lowercase* image file extensions ('jpg' extension of uploaded file counts as 'jpeg') maxsize: iterable containing maximum width and height of the image minsize: iterable containing minimum width and height of the image Use (-1, -1) as minsize to pass image size check. Examples: Check if uploaded file is in any of supported image formats: INPUT(_type='file', _name='name', requires=IS_IMAGE()) Check if uploaded file is either JPEG or PNG: INPUT(_type='file', _name='name', requires=IS_IMAGE(extensions=('jpeg', 'png'))) Check if uploaded file is PNG with maximum size of 200x200 pixels: INPUT(_type='file', _name='name', requires=IS_IMAGE(extensions=('png'), maxsize=(200, 200))) |

Abstract classes can override this to customize issubclass(). This is invoked early on by abc.ABCMeta.__subclasscheck__(). It should return True, False or NotImplemented. If it returns NotImplemented, the normal algorithm is used. Otherwise, it overrides the normal algorithm (and the outcome is cached). |
