Hi everybody!
I need to create a program that read the color of two points on an image finding the points with random coordinates and that draw a line between the two points with the middle color between color pixel 1 and color pixel 2! I tried with this, but doesn't work!
PImage img;
PImage destinationimg;
float x1;
float y1;
float x2;
float y2;
float middlecolorpixel;
color colorpixel1;
color colorpixel2;
color linecolor;
String selectImg;
void setup() {
size (600,400);
String selectImg = selectInput();
img = loadImage(selectImg);
}
void draw() {
loadPixels ();
img.loadPixels();
image (img, 0, 0);
float x1 = random (5, width-6);
float y1 = random (5, height-6);
float x2 = random (x1 - 5, x1 + 5);
float y2 = random (y1 - 5, y1 + 5);
color colorpixel1 = get (x1, y1);
color colorpixel2 = get (x2, y2);
middlecolorpixel= ((colorpixel1 + colorpixel2)/2);
linecolor= color (middlecolorpixel);
stroke (linecolor);
line (x1, y1, x2, y2);
}
destinationimg.updatePixels();
image(destinationimg,0,0);
