Java实现颜色渐变算法
package org.example;import java.awt.Color;
public class ColorGradient {
public enum GradientType {
LINEAR,
HSV
}
public static Color interpolate(GradientType type, Color color1, Color color2, float t) {
switch (type) {
case LINEAR:
return linearInterpolation(color1, color2, t);
case HSV:
return hsvInterpolation(color1, color2, t);
default:
throw new IllegalArgumentException("Unknown gradient type: " + type);
}
}
private static Color linearInterpolation(Color color1, Color color2, float t) {
int r = (int) (color1.getRed() + (color2.getRed() - color1.getRed()) * t);
int g = (int) (color1.getGreen() + (color2.getGreen() - color1.getGreen()) * t);
int b = (int) (color1.getBlue() + (color2.getBlue() - color1.getBlue()) * t);
int a = (int) (color1.getAlpha() + (color2.getAlpha() - color1.getAlpha()) * t);
return new Color(r, g, b, a);
}
private static Color hsvInterpolation(Color color1, Color color2, float t) {
float[] hsv1 = Color.RGBtoHSB(color1.getRed(), color1.getGreen(), color1.getBlue(), null);
float[] hsv2 = Color.RGBtoHSB(color2.getRed(), color2.getGreen(), color2.getBlue(), null);
float h = (hsv1[0] + (hsv2[0] - hsv1[0]) * t);
float s = (hsv1[1] + (hsv2[1] - hsv1[1]) * t);
float v = (hsv1[2] + (hsv2[2] - hsv1[2]) * t);
return Color.getHSBColor(h, s, v);
}
public static void main(String[] args) {
Color color1 = new Color(255, 0, 0); // Red
Color color2 = new Color(0, 0, 255); // Blue
float t = 0.5f; // Midpoint
Color interpolatedColor = interpolate(GradientType.LINEAR, color1, color2, t);
System.out.println("Linear Interpolation: " + interpolatedColor);
interpolatedColor = interpolate(GradientType.HSV, color1, color2, t);
System.out.println("HSV Interpolation: " + interpolatedColor);
}
}以上代码实现了线性渐变和HSV渐变两种算法，HSV渐变看起来会更加平滑
