Testing the new site! The focus will be on Project Portfolio Management and Software Development. Hope everyone's having a great day!
Assumptions: Height stays the same (only the width changes) Keep original image aspect ratio and keep the image in the middle of the new size image Add black boxes on the 2 sides to respect the exiting image perspective Calculation for the new 16:9 size New width = 16 / 9 multiply by the height (note: we are trying to keep same height) E.g.: original size is 3840 x 2880 (4:3) New width = 16 / 9 * 2880 = 5120 New image size = 5120 x 2880 (16:9) Instruction using Paint to add 2 black bars on the side of the image Goal: increase image size from 3840 x 2880 to 5120 x 2880 First increase image width to 4480 (File -> Image Properties) Rotate 180 degrees <- this is the main trick :) Increase width to 5120 Use Fill tool to fill the 2 sizes with Black (or whichever color you like) Rotate 180 degrees to get back to the original format ---------------------- Just another note for my future reference :).
