Member Function Documentation

void FloodFilledImage::addFloodFill	(	ImageTraversal &	traversal,
		ColorPicker &	colorPicker
	)

Adds a flood fill operation to the FloodFillImage.

This function must store the operation, which will be used by animate.

Parameters

traversal	ImageTraversal used for this FloodFill operation.
colorPicker	ColorPicker used for this FloodFill operation.

[Part 2]

Animation FloodFilledImage::animate

(

unsigned

frameInterval

)

const

Creates an Animation of frames from the FloodFill operations added to this object.

Each FloodFill operation added by addFloodFill is executed based on the order the operation was added. This is done by:

1. Visiting pixels within the image based on the order provided by the ImageTraversal iterator and
2. Updating each pixel to a new color based on the ColorPicker

While applying the FloodFill to the image, an Animation is created by saving the image after every frameInterval pixels are filled. To ensure a smooth Animation, the first frame is always the starting image and the final frame is always the finished image.

(For example, if frameInterval is 4 the frames are:

• The initial frame
• Then after the 4th pixel has been filled
• Then after the 8th pixel has been filled
• ...
• The final frame, after all pixels have been filed)
