Detailed Description

Color palette is simple array of unsigned longs (color cells).

Constructor & Destructor Documentation

ZPalette::ZPalette

(

const ZConnect &

zconnect

)

Create empty palette

ZPalette::ZPalette

(

const ZPalette &

zpal

)

Create copy of the palette

virtual ZPalette::~ZPalette ( )

virtual

Just to make compiler happy

Member Function Documentation

virtual void ZPalette::add_color ( ColorPixel  theColorPixel )

virtual

Add color in palette (at the end)

Reimplemented in ZScaledPalette.

virtual void ZPalette::append_palette ( const char *  szPalName )

virtual

Append list of colors with palette of pointed name. Leading '-' means reverse order of colors. "c1:c2:...:cN" may be used for obtaining smooth palette.

ColorPixel ZPalette::color

(

unsigned

index

)

const

Get color by index

unsigned ZPalette::colors_count

(

)

const

Return count of colors in palette

Pixmap ZPalette::draw_palette	(	const ZSize &	zs,
		Logic	bReverse = FALSE,
		ZDimension	dim = zdHorizontal
	)		const

Create pixmap of given size with horizontal or vertical palette image (color bars)

ColorPixel& ZPalette::fetch_color

(

unsigned

index

)

Get or change color by index

virtual void ZPalette::insert_color ( unsigned  index, ColorPixel  theColorPixel  )

virtual

Insert color before pointed index

Reimplemented in ZScaledPalette.

virtual void ZPalette::load_palette ( const char *  szPalName )

virtual

Load palette with pointed name. Leading '-' means reverse order of colors. "c1:c2:...:cN" may be used for obtaining smooth palette.

virtual void ZPalette::remove_color ( unsigned  index )

virtual

Add several colors to fit the gradient from one given color to another. Delete color at pointed index

Reimplemented in ZScaledPalette.

virtual void ZPalette::reset_colors ( )

virtual

Delete all colors

Reimplemented in ZScaledPalette.

virtual void ZPalette::revert_order ( )

virtual

Revert order of colors

Reimplemented in ZScaledPalette.

virtual void ZPalette::set_smooth_rate ( int  n = 100 )

virtual

Set number of smooth colors (100 by default). Should be set before load_palette()/append_palette().

Member Data Documentation

int ZPalette::nSmooth

protected

      Number of resulting color after building

smooth palette.
