Examples
示例显示如何选择一个简单的图像区域,基于任何像素的色调和颜色,使用Magic Wand工具。
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
});
}示例显示如何使用 Magic Wand 工具选择图像的复杂区域,以及与面具(逆转、联盟、子文)互动的能力。
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);
