Constructor Detail

Palette

public Palette(int size)

Creates a new palette

Parameters:

size - The number of colors in the palette.

Method Detail

addColor

public boolean addColor(byte red,
                        byte green,
                        byte blue)

Adds a color to the PCX's palette.

Parameters:

red - - The red value of the new color (unsigned byte).

green - - The green value of the new color (unsigned byte).

blue - - The blue value of the new color (unsigned byte).

Returns:

True if the color can be added, false if there are already the maximum number colors.

makeTransparent

public boolean makeTransparent(int index)

Makes a certain color in the palette transparent. TODO: Ensure that this actually works. Going by setColor, it looks like we'll have to manually change all the pointers in the bitmap array to point to the new color. It'd be nice if they just pointed to the place in the palette rather than at the actual color.

Parameters:

index - - The color that is to become transparent.

Returns:

- True if the index was valid, false otherwise

setColor

public void setColor(int index,
                     Color color)

Changes the color that was at position index in the palette to a new color, color.

Parameters:

index - - The index in the palette of the color to be replaced.

color - - The new color.

getColor

public Color getColor(byte index)

Returns the color of a color within the PCX's palette.

Parameters:

index - - The index within the palette (unsigned byte).

Returns:

- The color corresponding to that index

toString

public String toString()

Overrides:
