Description


<type 'builtin_function_or_method'>








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).


Attributes


IS_IMAGE.__subclasshook__.__call__ <type 'method-wrapper'> belongs to class <type 'method-wrapper'>
x.__call__(...) <==> x(...)

IS_IMAGE.__subclasshook__.__class__ <type 'type'> extends (<type 'object'>,) belongs to class <type 'type'>
<attribute '__doc__' of 'builtin_function_or_method' objects>

IS_IMAGE.__subclasshook__.__cmp__ <type 'method-wrapper'> belongs to class <type 'method-wrapper'>
x.__cmp__(y) <==> cmp(x,y)

IS_IMAGE.__subclasshook__.__name__ <type 'str'> belongs to class <type 'str'>
str(object='') -> string Return a nice string representation of the object. If the argument is a string, the return value is the same object.

IS_IMAGE.__subclasshook__.__ne__ <type 'method-wrapper'> belongs to class <type 'method-wrapper'>
x.__ne__(y) <==> x!=y

IS_IMAGE.__subclasshook__.__reduce__ <type 'builtin_function_or_method'> belongs to class <type 'builtin_function_or_method'>
helper for pickle

IS_IMAGE.__subclasshook__.__reduce_ex__ <type 'builtin_function_or_method'> belongs to class <type 'builtin_function_or_method'>
helper for pickle

IS_IMAGE.__subclasshook__.__repr__ <type 'method-wrapper'> belongs to class <type 'method-wrapper'>
x.__repr__() <==> repr(x)

IS_IMAGE.__subclasshook__.__self__ <type 'type'> extends (<class 'gluon.validators.Validator'>,) belongs to class <type 'type'>
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)))

IS_IMAGE.__subclasshook__.__setattr__ <type 'method-wrapper'> belongs to class <type 'method-wrapper'>
