Detailed Description

A data interface for the color bar widget in the color picker panel.

Member Enumeration Documentation

enum ISpectrumData::LocationType

LocationType specfies where the click occurred in the color bar.

Enumerator
kNotInSpectrumBar	kNotInSpectrumBar indicate that the click is not in the color bar.
kInColorBar	kInColorBar indicate that the click is in the color bar.
kInMinSwatch	kInMinSwatch indicate that the click is in the minimum swatch proxy at the end of the color bar.
kInMaxSwatch	kInMaxSwatch indicate that the click is in the maximum swatch proxy at the end of the color bar.

Member Function Documentation

virtual uint8* ISpectrumData::GetTable1 ( ) const

pure virtual

Returns the pointer to Table1

virtual uint8* ISpectrumData::GetTable2 ( ) const

pure virtual

Returns the pointer to Table2

virtual void ISpectrumData::InitializeTables ( const int32  colorspace, const int16  width, const int16  height, bool16  doHiRes, bool16  doBWSwatch  )

pure virtual

Initialize two tables internally required to setup the default color bar bitmap. Four color spaces are suppported: CMYK, RGB, LAB, and Grayscale. Table1 contains the ramps column-wise. Table2 contains the ramps row-wise.

Parameters

colorspace	specifies the color space to set up the tables for.
width	specifies the pixel width of the table.
height	specifies the pixel height of the table.
doHiRes	whether or not we are operating in hi-res mode (affects position-to-color calculations).
doBWSwatch	is true if color bar setup includes the minimum and maximum swatch proxy.

virtual void ISpectrumData::InitializeTransition ( const int32  colorspace, const ColorArray &  components, const int16  width, const int16  height, bool16  doHiRes, bool16  doBWSwatch  )

pure virtual

Initialize the transition table internally required to setup the tint transition.

Parameters

colorspace	specifies the color space to set up the transition table for.
components	specifies the color values for the transition table.
width	specifies the pixel width of the transition table.
height	specifies the pixel height of the transition table.
doHiRes	whether or not we are operating in hi-res mode (affects position-to-color calculations).
doBWSwatch	is true if color bar setup includes the minimum and maximum swatch proxy.

virtual ColorArray ISpectrumData::MapPositionToColor ( const PMPoint &  where, bool16  wantTransitionFract = kTrue  )

pure virtual

Map a position in the color bar to a color value represented by the point.

Parameters

where	specifies the point in the color bar.
wantTransitionFract	is true if mapping for transition table.

Returns

a color value in the color space of the color bar.

virtual LocationType ISpectrumData::MapPositionToLocation ( const PMPoint &  where )

pure virtual

Map a position in the color bar to location type represented by the point.

Parameters

where

specifies the point in the color bar.

Returns

a location type in the color color.
