public void vertical_stripes()
{
Pixel[] pixels = this.getPixels();
Pixel pixel = null;
int index = 0;
for (int x=0; x<this.getWidth(); x+=5){
for (int y=0; y<this.getHeight(); y++){
for (int i=0; i<2; i++){
if (i == 0){
pixel = pixels[index];
pixel.setColor(Color.red);
index++;
x=x+5;}
if (i == 1){
pixel = pixels[index];
pixel.setColor(Color.green);
index++;}
}
}
}
}
something isn't right about this. it only does one row of pixels. and the spacing is off too. could you give me an idea of what needs to happen? |
public void vertical_stripes()
{
// get the array of pixels from the current picture
Pixel[] pixels = this.getPixels();
// declare the variable that will refer to the current pixel
Pixel pixel = null;
for(int i = 0; i < pixels.length; i++){
// get the current pixel
pixel = pixels[i];
pixel.setBlue(0);
pixel.setRed(255);
pixel.setGreen(0);
i = i+3;
}
for(int j = 2; j < pixels.length; j++){
// get the current pixel
pixel = pixels[j];
pixel.setBlue(0);
pixel.setRed(0);
pixel.setGreen(255);
j = j+3;
}
} This one worked for me... but i'm worried that it just happened to work because the pic had just the right amount of pixels in its width, is that right? |
public void addVert(){
Pixel[] pixels = this.getPixels();
Pixel pix = null;
int srcy=0; int srcx=0;
while (int y < getHeight()){
while (int x < getWidth()){
pix= this.getPixel(srcx,srcy); pix.setColor(Color.red);srcx+3;
pix= this.getPixel(srcx,srcy); pix.setColor(Color.green);srcx+3;
}srcy++;}this.show;return this;}This one only does the first line.... please help |

This worked for me with several pictures!public void vertical_stripes(){
int stripe = 0;
Pixel pixelA;
Pixel pixelB;
for (int y=0; y < this.getHeight(); y++){
pixelA = this.getPixel(stripe, y);
pixelA.setRed(255); pixelA.setBlue(0); pixelA.setGreen(0);
pixelB = this.getPixel((stripe+2),y);
pixelB.setRed(0); pixelB.setBlue(0); pixelB.setGreen(255);
stripe = stripe + 4;
}
