Class Bitmap

source code

Wrapper class for the PIL Image class.

The main purpose for this base class is to provide a consistent interface for defining bitmaps constructed in various different ways. The resulting bitmap is a PIL Image object that can be accessed using the normal PIL interface.

If subclasses use the _arrayToImage() function provided, any pixels larger than the maximum that can be displayed will be counted before they are clipped; these are stored in the clipped_pixels attribute.

Method Details [hide private]

__init__(self, image)
(Constructor)

source code 
x.__init__(...) initializes x; see x.__class__.__doc__ for signature
Overrides: object.__init__
(inherited documentation)

__getstate__(self)

source code 
Return the object's state (as in the superclass), but replace the 'image' attribute's Image with a string representation.
Overrides: param.parameterized.Parameterized.__getstate__

__setstate__(self, state)

source code 
Load the object's state (as in the superclass), but replace the 'image' string with an actual Image object.
Overrides: param.parameterized.Parameterized.__setstate__

zoom(self, factor)

source code 
Return a resized Image object, given the input 'factor' parameter. 1.0 is the same size, 2.0 is doubling the height and width, 0.5 is 1/2 the original size. The original Image is not changed.

_arrayToImage(self, inArray)

source code 

Generate a 1-channel PIL Image from an array of values from 0 to 1.0.

Values larger than 1.0 are clipped, after adding them to the total clipped_pixels. Returns a one-channel (monochrome) Image.


Class Variable Details [hide private]

clipped_pixels

int(x[, base]) -> integer

Convert a string or number to an integer, if possible. A floating point argument will be truncated towards zero (this does not include a string representation of a floating point number!) When converting a string, use the optional base. It is an error to supply a base when converting a non-string. If base is zero, the proper base is guessed based on the string content. If the argument is outside the integer range a long object will be returned instead.

Value:
0
