 * Fixed ROIs, annotations and analysis results (centroids, detected peaks, contours...) being shifted by one pixel after a flip or a 90° rotation of an image; after a 90° rotation of a non-square image, or of an image whose coordinates do not start at zero, analysis results even ended up far from the features they describe. They now move exactly with the pixels; for images with non-uniform coordinates, circles, ellipses and polygons are moved approximately when the pixels are reversed along a non-uniform axis (a circle does not stay a circle). ROIs defined in pixel indices are also moved correctly, and inverse ROIs (which mask the inside of their shape) no longer become normal ROIs after these operations, a translation or a distribution of images on a grid
