Canvas changes not working, page freezes?

Question

JavaScript

Tell me, please, already several people are trying to solve the problem, no one can.
There is a project, uploaded to github
. At the moment I am writing a function to change the image -> red color filter.
When you click on the "red" checkbox, the page freezes terribly, chrome starts to crash, but does not give any errors.
The image is in the same folder with the project.
What is it connected with? How to make everything work properly?

Answer 1

You have a cool condition in the loop: 1 < imageData.data.length. Maybe not after all 1, right i?
