From ec097d63ef9064cc495d9126b54dc772e83137d7 Mon Sep 17 00:00:00 2001 From: Stefan Klug Date: Mon, 16 Dec 2024 16:40:43 +0100 Subject: libcamera: geometry: Add Rectangle::transformedBetween() Handling cropping and scaling within a complicated pipeline involves transformations of rectangles between different coordinate systems. For example the full input of the dewarper (0,0)/1920x1080 might correspond to the rectangle (0, 243)/2592x1458 in sensor coordinates (of a 2592x1944 sensor). Add a function that allows the transformation of a rectangle defined in one reference frame (dewarper) into the coordinates of a second reference frame (sensor).
