Dear all! Until recently, I've been using libvigraimpex to open image files for lux. lux is using strided nD arrays for image data storage (namely, vigra::MultiArrays) , and libvigraimpex can directly read into these data structures. I wasn't too happy with the supported range of image types which libvigraimpex offers - e.g. newer formats are missing. So I was looking for a replacement, but I found no library reading the data into strided nD arrays - until I found OpenImageIO <https://openimageio.readthedocs.io> (OIIO for short). This library is extremely comprehensive, and since it accepts strides, I could just 'slot it in' where I used libvigraimpex before - with a few hundred lines of glue code.
I have built an experimental lux AppImage (so, this is for Linux only) to demonstrate just how versatile this library is. Just to whet your appetite, here are three really cool things you can do: - open videos, viewing single images - open RAW files - open HEIF and HEIC files Because OIIO can open such a wide range of image formats, the lux build I offer shows all possible files and does not pre-select images - the filter list would be too large. When opening videos, note that you can navigate through the single images with the 'subimage' control, at the bottom of the View Control Panel. If you'd like to give the AppImage a spin, here's the link: https://bitbucket.org/kfj/pv/downloads/lux-with-oiio-experimental-x86_64.AppImage Because OIIO plays so well with vigra data structures, it might be an interesting option for hugin and relatives. It's RAW support, for example, uses libraw, which is a wrapper around the code for dcraw, which, in turn, is one of the raw converters hugin can employ as helper programs. lux can process many PTO files, among them PTOs which refer to raw source images. While the hugin process calls dcraw (when so configured) to convert the raw files to TIFF and then takes it from there, lux can now directly open PTOs with raw source images and stitch them with a single keystroke (Shift+E)! Check it out. Just keep in mind lux is doing it all in-memory and you need huge amounts of memory to stitch large panoramas - and for PTOs with raw files, you must have been using dcraw - otherwise the geometry won't quite fit, because most raw converters cut off o bit of margin. The versatility comes at a price: you'll notice that the new AppImage is *much* larger than the ones before. This is because it packs all the helper libraries as well. -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
