Detailed Description

Represents a 16-bit 5:6:5 color, the native format used by our display.

This is a C++ Plain Old Data (POD) type.

RGB565 colors can be converted to and from 8-bit RGB, and this class can perform simple color blending.

Member Function Documentation

static RGB565 Sifteo::RGB565::fromRGB ( uint32_t rgb )

inlinestatic

Create an RGB565 color from a packed-pixel 24-bit RGB color.

Blue is in the least significant byte, making this convenient for specifying colors in the common hexadecimal format 0xRRGGBB.

inline

Linear interpolation between this color and another color.

When alpha=255, this returns the "other" color. When alpha=0, we return this color. Values in-between will result in a correspondingly blended color.

uint32_t Sifteo::RGB565::packedRGB ( ) const

inline

Return the color as a packed 24-bit RGB value.

Blue is in the least significant byte. The resulting color, in hexadecimal, has the form 0xRRGGBB.
