IColorPalette customPalette)
Parameter | Type | Description |
---|---|---|
ditheringMethod | DitheringMethod | The dithering method. |
bitsCount | Int32 | The final bits count for dithering. |
customPalette | IColorPalette | The custom palette for dithering. |
Examples
The following example loads a TIFF image and performs threshold and floyd dithering using different palette depth.
[C#]
string dir = "c:\\temp\\";
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.tif"))
{
Aspose.Imaging.FileFormats.Tiff.TiffImage tiffImage = (Aspose.Imaging.FileFormats.Tiff.TiffImage)image;
// Perform threshold dithering using 4-bit color palette which contains 16 colors.
// The more bits specified the higher quality and the bigger size of the output image.
// Note that only 1-bit, 4-bit and 8-bit palettes are supported at the moment.
tiffImage.Dither(Aspose.Imaging.DitheringMethod.ThresholdDithering, 4, null);
tiffImage.Save(dir + "sample.ThresholdDithering4.png", new Aspose.Imaging.ImageOptions.PngOptions());
}
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.tif"))
{
Aspose.Imaging.FileFormats.Tiff.TiffImage tiffImage = (Aspose.Imaging.FileFormats.Tiff.TiffImage)image;
// Perform floyd dithering using 1-bit color palette which contains only 2 colors - black and white.
// The more bits specified the higher quality and the bigger size of the output image.
// Note that only 1-bit, 4-bit and 8-bit palettes are supported at the moment.
tiffImage.Dither(Aspose.Imaging.DitheringMethod.FloydSteinbergDithering, 1, null);
tiffImage.Save(dir + "sample.FloydSteinbergDithering1.png", new Aspose.Imaging.ImageOptions.PngOptions());
}
