align_image_stack: unrecognized option '--version'

align_image_stack: align overlapping images for HDR creation align_image_stack version 2017.0.0.eac5e8cc546e Usage: align_image_stack [options] input files Valid options are: Modes of operation: -p file Output .pto file (useful for debugging, or further refinement) -a prefix align images, output as prefix_xxxx.tif -o output merge images to HDR, generate output.hdr Modifiers -v Verbose, print progress messages. Repeat for higher verbosity -e Assume input images are full frame fish eye (default: rectilinear) -t num Remove all control points with an error higher than num pixels (default: 3) --corr=num Correlation threshold for identifing control points (default: 0.9) -f HFOV approximate horizontal field of view of input images, use if EXIF info not complete -m Optimize field of view for all images, except for first. Useful for aligning focus stacks with slightly different magnification. -d Optimize radial distortion for all images, except for first. -i Optimize image center shift for all images, except for first. -x Optimize X coordinate of the camera position. -y Optimize Y coordinate of the camera position. -z Optimize Z coordinate of the camera position. Useful for aligning more distorted images. -S Assume stereo images - allow horizontal shift of control points. -A Align stereo window - assumes -S. -P Align stereo window with pop-out effect - assumes -S. -C Auto crop the image to the area covered by all images. -c num number of control points (per grid) to create between adjacent images (default: 8) -l Assume linear input files -s scale Scale down image by 2^scale (default: 1 [2x downsampling]) -g gsize Break image into a rectangular grid (gsize x gsize) and attempt to find num control points in each section (default: 5 [5x5 grid] ) --distortion Try to load distortion information from lens database --use-given-order Use the image order as given from command line (By default images will be sorted by exposure values.) --gpu Use GPU for remapping -h Display help (this text)
