Member Function Documentation

RGBAPixel rainbowColorPicker::operator() ( int  x, int  y  )

virtual

Picks the color for pixel (x, y).

This function must be defined in the subclass! It chooses a color for the given point (x,y) and returns it.

For example, the gridColorPicker::operator()() function is defined so as to return a color if x or y is divisible by the grid spacing, and white otherwise. In this way, if you colored each pixel in an image whatever color the gridColorPicker chose, you would end up with a grid.

For the other patterns, you will have to figure out how to "pick" the colors.

Parameters

x	The x coordinate of the pixel we want to pick a color for.
y	The y coordinate of the pixel we want to pick a color for.

Returns

The color that the pixel at (x, y) should be.

Implements colorPicker.
