Question

This piece of code above is to flip an image horizontally in Java, does anyone know how to write the code that flips image vertically? Thank you

//for each row, swap its contents from left to right for (int row = 0; row the Image. getHeight(); row++) { for (int col = 0; col the Image . getWidth ( ) / 2; col++) { // given a column: i, its pair is column: vidth) - i - 1 /1 e.g. with a vidth of 10 /colunn 0 is paired vith column 9 I column 1 is paired vith column 8 etc. Pixel temp = data[row][col]; data[row] [ col] data[row] [the Image . getWidth () -col -j; data[row] [ the Image. getWidth() - col -j = temp ; update the image vith the moved pixels theImage.setData(data)

Explanation / Answer

Hi, The code to flip vertically is almost similar

for(int col=0;i<theImage.getWidth();col++){
   for(int row=0;row<theImage.getHeight()/2;row++){
       Pixel temp = data[row][col];
       data[row][col] = data[theImage.getHeight()-row-1][col];
       data[theImage.getHeight()-row-1][col] = temp;
   }
}

theImage.setData(data)
