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.
Implemented in gradientColorPicker, gridColorPicker, solidColorPicker, and rainbowColorPicker.
