Examples
Primjer pokazuje kako odabrati jednostavno područje slike na temelju tona i boje bilo kojeg piksela pomoću alata Magic Wand.
var imageFilePath = "input.png";
using (RasterImage image = (RasterImage)Image.Load(inputFilePath))
{
// Create a new mask using magic wand tool based on tone and color of pixel (120, 100) with custom threshold equal to 150
MagicWandTool
.Select(image, new MagicWandSettings(120, 100) { Threshold = 150 })
// Apply mask to the image
.Apply();
// Save image with forced transparency color type option
image.Save(outputFilePath, new ImageOptions.PngOptions()
{
ColorType = PngColorType.TruecolorWithAlpha
});
}Primjer pokazuje kako odabrati složeno područje slike pomoću Magic Wand alata i sposobnost za interakciju s maskama (invert, union, substrata).
var imageFilePath = "input.png";
using (RasterImage image = (RasterImage)Image.Load(inputFilePath))
{
// Create a new mask using magic wand tool based on tone and color of pixel (845, 128)
MagicWandTool.Select(image, new MagicWandSettings(845, 128))
// Union the existing mask with the specified one created by magic wand tool
.Union(new MagicWandSettings(416, 387))
// Invert the existing mask
.Invert()
// Subtract the specified mask created by magic wand tool with specified threshold from the existing one
.Subtract(new MagicWandSettings(1482, 346) { Threshold = 69 })
// Subtract four specified rectangle masks from the existing mask one by one
.Subtract(new RectangleMask(0, 0, 800, 150))
.Subtract(new RectangleMask(0, 380, 600, 220))
.Subtract(new RectangleMask(930, 520, 110, 40))
.Subtract(new RectangleMask(1370, 400, 120, 200))
// Feather mask with specified settings
.GetFeathered(new FeatheringSettings() { Size = 3 })
// Apply mask to the image
.Apply();
// Save image
image.Save(outputFilePath);
}Methods
Process(Sljedeći Članak Int[], Točka i točka)
Proizvodnja punih piksela.
public void Process(Rectangle pixelsRectangle, int[] pixels, Point start, Point end)Parameters
pixelsRectangle Rectangle
Pikseli su pravokugli.
pixels int
[]
32-bitni ARGB pikseli
start Point
Ako nije jednako (levo, vrh) znači da to nije pun pravokugli imamo.
end Point
Ako nije jednako (pravo, donje) znači da to nije pun pravokugli imamo.
Select(RasterImage i MagicWandSettings)
Stvaranje novog Aspose.Imaging.MagicWand.ImageMasks.ImagicBitMask temelji se na Wl17.Settings-u i izvoru _www.wl17.
public static ImageBitMask Select(RasterImage source, MagicWandSettings settings)Parameters
source RasterImage
