public static IColorPalette getCloseImagePalette(RasterImage image, Rectangle destBounds, int entriesCount, boolean useImagePalette)
Gets color palette from raster image (palletizes image) in case the image does not have one. In case palette exists it will be used instead performing calculations.
Parameters:
| Parameter | Type | Description |
|---|---|---|
| image | RasterImage | The raster image. |
| destBounds | Rectangle | The destination image bounds. |
| entriesCount | int | The desired entries count. |
| useImagePalette | boolean | If set, it will use its own image palette if available |
Returns: IColorPalette - The color palette which starts with the most frequent colors from the image and contains entriesCount entries.
getCloseImagePalette(RasterImage image, int entriesCount)
