Question

**** In java matrix(2 dimensional array) size is fixed. so I have taken the new matrix (data2) in below code snippet. new matrix (data2) dimension is equal to transpose matrix's dimension of data. And I have sent each pixel value to the new matrix(data2). ***

    Pixel[][] data = theImage.getData();
   Pixel[][] data2 = new Pixel[theImage.getWidth()][theImage.getHeight()];

   for(int row=theImage.getHeight()-1; row>=0; row--){
       for(int col=0; col<theImage.getWidth(); col++){
           data2[col][(theImage.getHeight()-1)-row] = data[row][col];
       }
   }

   theImage.setData(data2);

This makes it rotate 90 degree clockwise. How would you edit it to go 90 degrees counter clockwise?

PLEASE DO NOT ANSWER IF YOU ARE NOT GOING TO ANSWER MY QUESTION! Thank you in advance!

Answer 1

Pixel[][] data = theImage.getData();
   Pixel[][] data2 = new Pixel[theImage.getWidth()][theImage.getHeight()];

for(int row = theImage.getWidth()-1;row>=0;row--){

    for(int col = 0;col<theImage.getHeight();col++){

     data2[theImage.getWidth()-1-row][col] = data[row][col];

}

}

theImageData.setData(data2);
