fading without tint

in Programming Questions • 4 months ago

Is there a way to fade in an image without tint?

Reason being is that I'm colouring a shape with tint, which stops it working

tint (random(130, 255), random(130, 255), random(130, 255));
image(imagesMed[imageMedIndex], imageSY, imageMX, medS, medS);

more of your code might be good. even better a minimally working example.

the reason why is that offhand i'm not sure why you can't use tint() twice.

One trick is to put a rect fill with a transparency :

import processing.video.*;
Capture video;
int fade;
void setup() {
size(640, 480);
video = new Capture(this, 640, 480);
video.start();
fade = 0;
}
void captureEvent(Capture c) {
c.read();
}
void draw() {
image(video, 0, 0);
fade = (int)map(mouseX, 0, width, 0, 255);
fill(0, fade);
rect(0, 0, video.width, video.height);
}
