Methods
-
addImage(
Image image) → void - Add an image to the quantized color table.
-
color(
int index) → int - Get a color from the colorMap.
-
getIndexMap(
Image image) → Uint8List -
Convert the
imageto an index map, mapping to this colorMap. -
getQuantizedColor(
int c) → int -
Find the color closest to
cin the colorMap. -
lookup(
int c) → int -
Find the index of the closest color to
cin the colorMap. -
lookupRGB(
int r, int g, int b) → int -
Find the index of the closest color to
r,g,bin the colorMap. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
