Examples
L’exemple montre comment sélectionner une zone simple d’une image en fonction du ton et de la couleur de tout pixel en utilisant l’outil 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
});
}L’exemple montre comment sélectionner une zone compliquée d’une image en utilisant l’outil Magic Wand et la capacité à interagir avec les masques (invert, union, substrat).
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);
