Member Function Documentation

GetColorID() [1/2]

bool JXColorManager::GetColorID ( const JString &  name, JColorID *  id  ) const

overridevirtual

Returns true if it was able to allocate the requested read-only color. Accepts both names from the color database and hex specifications. (i.e. "red" or "#FFFF00000000")

Implements JColorManager.

GetColorID() [2/2]

JColorID JXColorManager::GetColorID

(

const unsigned long

systemColor

)

const

Converts a system color value into a ColorID

GetDisplay()

JXDisplay * JXColorManager::GetDisplay ( ) const

GetVisual()

Visual * JXColorManager::GetVisual ( ) const

inline

GetVisualClass()

int JXColorManager::GetVisualClass ( ) const

inline

GetXColor()

unsigned long JXColorManager::GetXColor

(

const JColorID

id

)

const

We scale each component to fit inside the number of bits in its mask. This means multiplying by (2^(mask length)-1)/(2^16-1). By ignoring the -1's, it becomes a bit shift. The bit shift produces cleaner levels of gray with 16-bit color and negligible difference on 24-bit color. Both produce inaccurate results when writing GIFs on 16-bit color.

GetXColormap()

Colormap JXColorManager::GetXColormap ( ) const

inline

GetXVisualInfo()

XVisualInfo JXColorManager::GetXVisualInfo ( ) const

inline

Nobody wants a "const XVisualInfo*", but it is too dangerous to return a non-const pointer to our data.
