Hello,
I’m trying to make a pencil sketch from a jpeg image,
I found this code using python libraries, but know nothing about Python.
Is there a way to do this in processing, also is there a way to do it without always showing the images?
I’ve reached this point so far…
```auto
void setup() {
size(800, 754);
// The image file must be in the data folder of the current sketch
// to load successfully
img = loadImage("headshot.jpg"); // Load the image into the program
}
void draw() {
// Displays the image at its actual size at point (0,0)
image(img, 0, 0);
// Displays the image at point (0, height/2) at half of its size
// image(img, 0, height/10, img.width/10, img.height/10);
//image(img, 0, 0);
delay (2000);
blend(img, 0, 0, 800, 754, 0, 0, 800,754, DODGE);
//delay (3000);
//image(img,0,0);
//filter(INVERT);
}
```

The steps are
destaurate the image
Color dodge the blend
Invert the layer
Apply a gaussian blur (of about 1 pixel)
Adjust the black level
I’m not sure how to use the HSL colormode with procesing
And also, how to get control with the gaussian layer
I’ve been able to output a desaturated jpeg from a photo editing package to start from.
```auto
PImage img; // Declare variable "a" of type PImage
void setup() {
noLoop();
size(800, 754);
// The image file must be in the data folder of the current sketch
// to load successfully
img = loadImage("headshotsat1.jpg"); // Load the image into the program
}
void draw() {
// Displays the image at its actual size at point (0,0)
image(img, 0, 0);
// Displays the image at point (0, height/2) at half of its size
// image(img, 0, height/10, img.width/10, img.height/10);
//image(img, 0, 0);
blend(img, 0, 0, 800, 754, 0, 0, 800,754, DODGE);
// image(img,800,0);
filter(INVERT);
// invert applies to the whole canvas
filter(BLUR,5);
// blur aplies to whole canvas
}
```
