Question

我真的需要java程序的帮助......我在运行程序时遇到错误。我的目标是将两个图像组合成一个三维图像。将使用红色/蓝色眼镜观看这些图像以提供3D效果。最终图像将尝试成为原始原始图像中对象的灰度。在尝试创建3D图像之前，我必须验证两个图像是否具有相同的宽度和高度。如果图像不匹配，请打印出错误消息并退出程序。

错误：无法解析宽度

    height cannot be resolved

我写的节目如下......

public class 3dImage {

    public static void main(String[] args) {

        // Access and open the picture
        String filename = FileChooser.pickAFile ();
        Picture p1 = new Picture (filename);

        //second picture
        String filename2 = FileChooser.pickAFile ();
        Picture p2 = new Picture (filename);

        //get the width and height from p1 and p2
        Picture p3;
        p3 = new Picture (width, height);

        // call the method to modify the Pictture
        modifyPicture (p1, p2, p3);

        // explore (display) the picture    
        p3.explore();
    }  // end of main


    public static void modifyPicture (Picture p1, Picture p2, Picture p3) {

        // get the width and height of the picture
        int width = p1.getWidth();
        int height = p1.getHeight();

        //shows width and height
        System.out.println ("Width: " + width + ", Height: " + height);

        // loop over the pixels
        for (int xPos = 0 ; xPos < width ; ++xPos) {
            for (int yPos = 0 ; yPos < height ; ++yPos) {         
                //  access the pixel to be modifed
                Pixel pix1 = p1.getPixel (xPos, yPos);
                Pixel pix2 = p2.getPixel (xPos, yPos);
                Pixel pix3 = p3.getPixel (xPos, yPos);  

                // modify the pixel 

                int redAmount = pix1.getRed (255);
                int greenAmount = pix1.getGreen (0);
                int blueAmount = pix1.getBlue (0);                
                int grayAmount1 = (int)(redAmount * 0.299 + greenAmount * 0.587 + blueAmount * 0.114);   

                redAmount = pix2.getRed(0);
                greenAmount = pix2.getGreen(255);
                blueAmount = pix2.getBlue(255);
                int grayAmount2 = (int)(redAmount * 0.299 + greenAmount * 0.587 + blueAmount * 0.114);

                pix3.setRed (grayAmount1);
                pix3.setGreen (grayAmount2);
                pix3.setBlue (grayAmount2);
                // …
            }
        }
    }
}

我被困在这里，我需要帮助..

Answer 1

p3 = new Picture (width, height);

未声明width或height。您需要声明它们并设置为适当的值。正如您在modifyPicture函数中所做的那样。

确保p1，p2和p3具有相同的尺寸，否则modifyPicture将无法正常工作。

请在java帮助中创建一个3d图像
