public IndexColorModel getIndexColorModel(int bits)
public ColorTable Clone()
public int GetPaletteInterpretation()
The returned value is used to interprete the values in the GDALColorEntry.
public int GetCount()
public Color GetColorEntry(int entry)
entry
- entry offset from zero to GetCount()-1.public void SetColorEntry(int entry, Color centry)
The passed in entry must match the color interpretation of the table to which it is being assigned.
The table is grown as needed to hold the supplied offset.
entry
- entry offset from zero to GetCount()-1.centry
- value to assign to table.public void CreateColorRamp(int nStartIndex, Color startcolor, int nEndIndex, Color endcolor)
Automatically creates a color ramp from one color entry to another. It can be called several times to create multiples ramps in the same color table.
nStartIndex
- index to start the ramp on the color table [0..255]startcolor
- a color value to start the rampnEndIndex
- index to end the ramp on the color table [0..255]endcolor
- a color value to end the ramp
