The rotation is lossless so quality is not affected. To do this, select all your images and select JPG Lossless transformations from the Tools menu or toolbar. This will ensure that the images are oriented properly when viewing in any graphic programs. After rotation, the orientation tag of the Exif header is set to '1' (normal orientation). XnView allows you to process your images with an arsenal of editing tools: Resize, Rotate, Crop Lossless. For windows, you need to get a copy of it. This program is present in most Linux distributions. The program 'jpegtran' is used to perform the rotation. The program would do a guess to supply a missing dot or dash to generate a character based on what it heard and looking up valid Morse code characters. Permanent rotation Also, you can rotate permanently the images based on the EXIF information. Using the 'Orientation' tag of the Exif header, rotate the image so that it is upright. Those who used iambic keyers, vibroplexes and such it would do real well in getting a proper decode. It even calculated the approximate speed in WPM and displayed it. I used a subroutine that checked once a second to see when the characters were actually arriving and the length of dots, dashes and spaces the operator was sending adjusting the sample timing to fit. It started out at 8 WPM using the weights suggested for sending proper CW. Features of XnView MP It supports Film view, Full-screen view, and Thumbnail View.
