From 95bc9b463b87236d30d86626e1052e6979d6510f Mon Sep 17 00:00:00 2001 From: Berke Kocaoğlu Date: Thu, 22 Dec 2022 11:21:40 +0000 Subject: add brightness and contrast (#396) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Imlib2 supports modifying gamma, brightness and contrast directly while sxiv only supports gamma. Makes sense to extend it to brightness and contrast as well. * Since color corrections need to be aware of each other, they have been refactored into one centralized function. * This also makes the code more hackable as it makes it easier to add more color correction functions without them interfering with each other.
