Class Bitmap

              Bitmap

Bitmap class. Based on Image, but has methods for blobs, etc.

Method Summary
	`__init__(self, width, height, init_val)`
	`avgColor(self, img)` Return an n-tuple of the average color of the image where the bitmap is true, where n is the depth of img.
	`display(self)` Display bitmap ASCII art.
Inherited from PyrobotImage
	`convolve(self, convmask, bit, threshold)`
	`cropPixels(self, l, t, r, b)` cropPixels() ------------ crops pixels in the amount specified from left, top, right, and bottom if unspecified, right is assumed to be the same as left and bottom the same as top.
	`get(self, x, y, offset)` Get a pixel value.
	`getBitmap(self, cutoff, cutoff2, mode)` getBitmap()...
	`getCol(self, x)` Get the entire col, in tuples...
	`getColorFilter(self, r, g, b)` returns a filtered image r,g,b values indicate percentage of each color to keep eg.
	`getDim(self)`
	`getGrayScale(self)` Method to convert depth 3 color into depth 1 grayscale...
	`getPlane(self, colorPlane)`
	`getRow(self, y)` Get the entire row, in tuples...
	`getScaledImage(self, xscale, yscale, mode)` return a scaled version of the current image...
	`getVal(self, x, y)` Get the entire color value of the pixel in quetion, returned as a tuple.
	`histogram(self, cols, rows, initvals)` Creates a histogram.
	`incr(self, x, y, offset)` Method to increment a pixel value.
	`loadFromFile(self, filename)` Method to load image from file.
	`reset(self, vector)` Reset an image to a vector.
	`resetToColor(self, r, g, b)` reset the image to a specified color...
	`saveToFile(self, filename)` Method to save image to a file.
	`setVal(self, x, y, val)` Method to set the entire RGB value of a pixel.
	`swapPlanes(self, plane1, plane2)`

Method Details

avgColor(self, img)

Return an n-tuple of the average color of the image where the bitmap is true,
where n is the depth of img.  That is, using the bitmap as a mask, find the average color of img.
img and self should have the same dimensions.

display(self)

Display bitmap ASCII art.
