图像圆角按钮JavaFX

Question

我使用圆形按钮，我想在里面有一个图像。问题是图像位于中心而不是左侧甚至已经调用

loadButton.setAlignment（Pos.BASELINE_LEFT）;

我得到的是上面的按钮，我需要的是下面的按钮。你知道在圆角下显示png的方法吗？

typedef struct
{
    unsigned char data[3];
} rgb;

rgb LUTYUVTORGB[256][256][256];

非常感谢！

而不是：

    import java.util.Scanner;
    public class A3Question1 
    {

public static void main(String[] args) 
{
    Scanner keyboard = new Scanner(System.in);
    boolean loop1 = false;
    boolean loop2 = false;
    boolean loop3 = false;
    int numNouns = 0, numAdjectives = 0;
    String[] nouns = new String[numNouns];
    String[] adjectives = new String[numAdjectives];

    System.out.println("-----------------------------------------");
    System.out.println("           Let's write a poem!           ");
    System.out.println("-----------------------------------------");
    System.out.println();

    while (!loop1)
    {
        System.out.print("How many nouns? (min 3): ");
        numNouns = keyboard.nextInt();

        if (numNouns < 3)
        {
            continue;
        }
        else
        {
            loop1 = true;
        }

        System.out.println("Enter " + numNouns + " nouns: ");
        nouns = new String[numNouns];

        for (int i = 0; i < numNouns; i++)
        {
            nouns[i] = keyboard.next();
        }
    }
    while (!loop2)
    {
        System.out.print("How many adjectives? (min 3): ");
        numAdjectives = keyboard.nextInt();

        if (numAdjectives < 3)
        {
            continue;
        }
        else
        {
            loop2 = true;
        }

        System.out.println("Enter " + numAdjectives + " adjectives: ");
        adjectives = new String[numAdjectives];

        for (int j = 0; j < numAdjectives; j++)
        {
            adjectives[j] = keyboard.next();
        }
    }

    while (!loop3)
    {
        System.out.println("\n-----------------------------------");
        System.out.println("        Here is my Java Poem!         ");
        System.out.println("           **LOOK AROUND**            ");
        System.out.println("-----------------------------------");
        System.out.println();

        boolean[] noDuplicate1 = new boolean[numNouns];
        boolean[] noDuplicate2 = new boolean[numAdjectives];

        for(int i = 0; i < 1000; i++)
        {               
            int num1 = (int) (Math.random() * numNouns); 
            int num2 = (int) (Math.random() * numAdjectives);

            if (noDuplicate1[num1] == false && noDuplicate2[num2] == false)
            {
                for (int j = 0; j < i; j++)
                {
                    System.out.print("\t");
                }
                System.out.println(adjectives[num2] + nouns[num1]);
                noDuplicate1[num1] = true;
                noDuplicate2[num2] = true;
            }
        }

        System.out.print("\nAnother poem? (y/n): ");
        String again = keyboard.next();

        if (again.charAt(0) == 'y' || again.charAt(0) == 'Y')
        {
            continue;
        }
        else
        {
            loop3 = true;
        }
    }

    System.out.println("Thank you for using the POEM GENERATOR! Have a good day!");         

    keyboard.close();
}

使用：

loadButton.setContentDisplay(ContentDisplay.LEFT);
