Detailed Description

This class provides color remapping support for SCI32 games.

Member Function Documentation

remapOff()

void Sci::GfxRemap32::remapOff

(

const uint8

color

)

Turns off remapping of the given color. If color is 0, all remaps are turned off.

remapAllOff()

void Sci::GfxRemap32::remapAllOff

(

)

Turns off all color remaps.

remapByRange()

void Sci::GfxRemap32::remapByRange	(	const uint8	color,
		const int16	from,
		const int16	to,
		const int16	delta
	)

Configures a SingleRemap for the remap color color. The SingleRemap will shift palette colors between from and to (inclusive) by delta palette entries when the remap is applied.

remapByPercent()

void Sci::GfxRemap32::remapByPercent	(	const uint8	color,
		const int16	percent
	)

Configures a SingleRemap for the remap color color to modify the brightness of remapped colors by percent.

remapToGray()

void Sci::GfxRemap32::remapToGray	(	const uint8	color,
		const int8	gray
	)

Configures a SingleRemap for the remap color color to modify the saturation of remapped colors by gray.

remapToPercentGray()

void Sci::GfxRemap32::remapToPercentGray	(	const uint8	color,
		const int16	gray,
		const int16	percent
	)

Configures a SingleRemap for the remap color color to modify the brightness of remapped colors by percent, and saturation of remapped colors by gray.

blockRange()

void Sci::GfxRemap32::blockRange	(	const uint8	from,
		const int16	count
	)

Prevents GfxRemap32 from using the given range of palette entries as potential remap targets.

Was DontMapToRange in SSCI.

remapEnabled()

bool Sci::GfxRemap32::remapEnabled ( uint8  color ) const

inline

Determines whether or not the given color has an active remapper. If it does not, it is treated as a skip color and the pixel is not drawn.

Note

SSCI uses a boolean array to decide whether a pixel is remapped, but it is possible to get the same information from _remaps, as this function does. Presumably, the separate array was created for performance reasons, since this is called a lot in the most critical section of the renderer.

remapColor()

uint8 Sci::GfxRemap32::remapColor ( const uint8  sourceColor, const uint8  targetColor  ) const

inline

Calculates the correct color for a target by looking up the target color in the SingleRemap that controls the given sourceColor. If there is no remap for the given color, it will be treated as a skip color.

remapAllTables()

bool Sci::GfxRemap32::remapAllTables

(

const bool

paletteUpdated

)

Updates all active remaps in response to a palette change or a remap settings change.

paletteChanged is true if the next palette in GfxPalette32 has been previously modified by other palette operations.
