Detailed Description

SkColorPalette holds an array of SkPMColors (premultiplied 32-bit colors) used by 8-bit bitmaps, where the bitmap bytes are interpreted as indices into the colortable.

SkColorPalette is thread-safe.

Constructor & Destructor Documentation

SkColorPalette()

SkColorPalette::SkColorPalette	(	const SkPMColor	colors[],
		int	count
	)

Copy up to 256 colors into a new SkColorPalette.

                                                                  {
    SkASSERT(0 == count || colors);
    SkASSERT(count >= 0 && count <= 256);
 
    fCount = count;
    fColors = reinterpret_cast<SkPMColor*>(sk_malloc_throw(count * sizeof(SkPMColor)));
 
    memcpy(fColors, colors, count * sizeof(SkPMColor));
}

Member Function Documentation

count()

int SkColorPalette::count ( ) const

inline

Returns the number of colors in the table.

Definition at line 31 of file SkColorPalette.h.

{ return fCount; }

operator[]()

SkPMColor SkColorPalette::operator[] ( int  index ) const

inline

Returns the specified color from the table. In the debug build, this asserts that the index is in range (0 <= index < count).

Definition at line 36 of file SkColorPalette.h.

                                          {
        SkASSERT(fColors != nullptr && (unsigned)index < (unsigned)fCount);
        return fColors[index];
    }

readColors()

const SkPMColor * SkColorPalette::readColors ( ) const

inline

Return the array of colors for reading.

Definition at line 42 of file SkColorPalette.h.

{ return fColors; }
