virtual Display::ColorModel casa::QtPCColorTable::colorModel

(

)

const [inline, virtual]

The non-indexed 'true' color depth that Qt supports, and the number of bits in a Qrgb.

This includes room for the alpha channel (yay). FYI, component byte order in Qrgb (most- to least-significant) is A-R-G-B.

Called by corresp.

Implements casa::PixelCanvasColorTable.

virtual void casa::QtPCColorTable::mapToColor	(	const Colormap *	map,
		Array< uInt > &	outArray,
		const Array< uInt > &	inArray,

	)		const [virtual]

Translate Array of colormap indices into graphics platform's colors.

Implements casa::PixelCanvasColorTable.

virtual void casa::QtPCColorTable::mapToColor	(	const Colormap *	map,
		Array< uChar > &	outArray,
		const Array< uChar > &	inArray,
		Bool	rangeCheck = True
	)		const [inline, virtual]

map [0,N-1] into colorpixels, where N is the current colormap size The values are returned as unsigned integers in their respective array.

Tip: The choice of what type to use should be guided by the number of graphics bitplanes available; For most systems with 8-bit color, uChar is optimal; Some systems with 12 bits per pixel with an alpha channel may require using the uLong;

Warning: uChar type may not have enough bits to hold the pixel index on some high-end graphics systems

Warning: uShort type may not have enough bits to hold the pixel index on some high-end graphics systems
