示例1: Bitmap
public Bitmap(int width, int height, int stride, PixelFormat pixelFormat, IntPtr scan0)
{
_width = width;
_height = height;
_stride = stride;
_pixelFormat = pixelFormat;
_scan0 = scan0;
_freeScan0 = false;
if (pixelFormat.IsIndexed())
Palette = new ColorPalette(new Color[pixelFormat.GetColorCount()]);
}示例2: Clone
public Bitmap Clone(PixelFormat pixelFormat)
{
List<Color> palette = null;
// indexed formats require 2 passes - one more pass to determines colors for palette beforehand
if (pixelFormat.IsIndexed())
{
Quantizer.Prepare(this);
// Pass: scan
ImageBuffer.ProcessPerPixel(this, null, 4, (passIndex, pixel) =>
{
var color = pixel.GetColor();
Quantizer.AddColor(color, pixel.X, pixel.Y);
return true;
});
// determines palette
palette = Quantizer.GetPalette(pixelFormat.GetColorCount());
}
// Pass: apply
Image result;
ImageBuffer.TransformImagePerPixel(this, pixelFormat, palette, out result, null, 4, (passIndex, sourcePixel, targetPixel) =>
{
var color = sourcePixel.GetColor();
targetPixel.SetColor(color, Quantizer);
return true;
});
return (Bitmap)result;
}示例3: Clone
public Bitmap Clone(PixelFormat pixelFormat)
{
if (pixelFormat == this._pixelFormat)
{
return new Bitmap(this);
}

// indexed formats require 2 passes - one more pass to determines colors for palette beforehand
if (pixelFormat.IsIndexed())
{
