Detailed Description

An accessor for the colormap, with up to 16 colors.

This colormap is used by the SOLID_MODE, FB32, FB64, and FB128 modes.

Colors are stored in 16-bit RGB565 format.

Note that, due to details of the radio compression protocol, even-numbered colormap indices will compress better in the FB32 mode. This means it can give better performance if you allocate the most common color values to even-numbered slots.

Member Function Documentation

ColormapSlot Sifteo::Colormap::operator[] ( unsigned  index )

inline

Return a ColormapSlot which references a single colormap entry on a single VideoBuffer.

You don't need to store this reference typically; for example:

vbuf.colormap[16].set(1.f, 0.f, 0.f);

void Sifteo::Colormap::setEGA ( )

inline

Set the entire palette to the traditional EGA 16-color palette.

void Sifteo::Colormap::setMono ( RGB565  color0, RGB565  color1  )

inline

Set a monochrome palette, in entries [0] and [1].

This is common in the two-color modes, FB64 and FB128.

void Sifteo::Colormap::setMono ( uint32_t  color0, uint32_t  color1  )

inline

Set a monochrome palette, in entries [0] and [1].

This is common in the two-color modes, FB64 and FB128.

Colors are specified as packed RGB values, in the format 0xRRGGBB.
