Colour functions

setTextColor(uint_16 FG, uint_16 BG);

• FG >> FOREGROUND required
• BG >> BACKGROUND optional Adding background colour overwrites existing text automatically

pushColor(uint16_t COLOUR, uint32_t LEN);

Push a single pixel.

• COLOUR >> Standard colour.
• LEN >> Optional push to more than one pixel.

pushColors(uint16_t *data, uint32_t LEN, bool SWAP);

Push an array of pixels. Assumed that setAddrWindow() has been called.

• *data >> Array
• LEN >> Number of bytes.
• SWAP >> Optional byte order ??
  REF setAddrWindow()

writeColor() KEYWORD2

color565(R,G,B); ?

• 5 bits for Red from #FF
• 6 bits for Green from #FF
• 5 bits for Blue from #FF

color8to16(uint_8 COLOUR);

Convert 8 bit colour to 16 bit.

• 8 Bits > 3 bits red, 3 bits green, 2 bits blue
• 16 Bits > 5 bits red, 6 bits green, 5 bits blue

color16to8(uint_16 COLOUR);

Convert 16 bit colour to 8 bit.

• 8 Bits > 3 bits red, 3 bits green, 2 bits blue
• 16 Bits > 5 bits red, 6 bits green, 5 bits blue

color16to24(uint_16 COLOUR);

Convert 16 bit colour to 24 bit.

• 16 Bits > 5 bits red, 6 bits green, 5 bits blue
• 24 Bits > 8 bits red, 8 bits green, 8 bits blue

color24to16(uint_32 COLOUR); ?? Does this handle Alpha ??

Convert 24 bit colour to 16 bit.

• 16 Bits > 5 bits red, 6 bits green, 5 bits blue
• 24 Bits > 8 bits red, 8 bits green, 8 bits blue

alphaBlend(int a, uint_16 FG, uint_16 BG);

• a >> Alpha 0 = 100% Background, 255 = 100% Forground
• FG >> Foreground colour
• BG >> Background colour

alphaBlend24(int a, uint_32 FG, uint_32 BG);

• a >> Alpha 0 = 100% Background, 255 = 100% Forground
• FG >> Foreground colour
• BG >> Background colour
