Image Splitter is a simple Qt-based tool to split individual images from a image collage. It can rotate and resize the collage before removing borders that surround the entire collage or individual images in a collage. It initially assumes all images in the collage are of same size and alignment, but cropping, and horizontal and vertical offsets, can be adjusted per image before saving.
Image Splitter should build without changes under Windows with Microsoft Visual C++ 2010-2015 and Qt 5.0-5.6. It should also build with minimal changes under most Linux distributions with Qt5 development packages installed.
