I've been working with batches of JPEG 2000 (.jp2) files recently. This would be much more convenient if I had an image viewer capable of displaying JPEG 2000 images instead of having to convert them to TIF files to see their content.
From what I've seen, no image viewing or photo management software found in the Ubuntu 20.04 repositories supports JPEG 2000 files, presumably due to potential patent issues with the format. The version of GIMP provided in 20.04 is capable of natively opening JPEG 2000 files, but it's a full-blown image editor and not fast/convenient enough replacement for an image viewer.
What ways are there of getting a J2K-capable image viewer on Ubuntu 20.04.1? I'd like to avoid Snaps and unofficial PPAs if at all possible. I'm willing to build stuff from source if it's necessary (I'm assuming it will be in this situation), but would like to avoid having to also build a long list of dependencies. Building with only JPEG 2000 support would be OK too, since I'll probably set this viewer to only open .jp2 files.
The nice thing about that is, being a commandline program I can convert hundreds of images quickly and automatically, and resize them, or perform other operations on them, with ImageMagick, and of course, display them with virtually any image viewer. I know this is an unsatisfying solution.
I spent a while trying to get ImageMagick to delegate to OpenJPEG's jpeg2000 converter, so that I could use ImageMagick's display program to show them directly, but I failed. I'm still not sure why, but compiling/installing openjpeg-2.3.0 gave me, among other things, opj_decompress, which let me convert jpg2 files. Unfortunately it only lets me convert to png, pnm, pgm, ppm, pgx, bmp, tif, raw, or tga. Not jpg.For example:
Arcgis Online doesn't provide the export map option in its map viewers (advanced and classic). However, there's a web app builder way in which you can print it, but it doesn't incorporate the changes done in advanced map viewer (such as blending of layers, symbolizations exclusive to the advanced version only). The whole point of introducing an advanced version of web map viewer gets jeopardized here itself.
JPEG viewer helps to view image as well as print the image easily. This tool is developed in such a way that user could easily find the print option by not looking in menu bar. Hence print option is at the bottom and can be seen just by hovering below. You can also set Orientation, Size, Margins, Scaling Mode, Alignment, etc.
I've seen this happen before with CMYK JPEG files - as Windows Picture Viewer is not colour managed these images often open and display for a moment, then switch to a 'black' display as the viewer can't replicate the colours correctly.
JPEGView is a basic image viewer which supports many of the most popular image formats either floating around the web or even RAW formats produced by more advanced digital SLR (or mirror-less) cameras. Some of the types JPEGView supports are those by Canon, Nikon and Sony Alphas.Despite the small size of the program, it doesn't lack in its support of file formats. What's more is its image editor functionality such as cropping, resizing, etc. In terms of image manipulation, it can change the brightness, contrast, hues and saturation.Luckily, JPEGView is also very easy on your system resources. It is lean and performs surprisingly well, even when dealing with RAW files from your digital camera.Overall, a very useful image viewer with many of the basic features most non-professional users would use. Best of all, JPEGView is completely free.Features of JPEGView
A viewer for pictures in JPEG and PNG formats. This add-in will help you avoid the hassle of having to convert pictures to G3P format so you can view them on your calculator! It can also work as an eActivity strip. Multiple zoom levels supported for JPEG viewing, and long file names supported in the file browser. Lossless and Progressive JPEG not supported. Interlaced PNG not supported.
It's easy to get the trusty old Windows Photo Viewer back -- simply open up Settings and go to System > Default apps. Under "Photo viewer" you should see your current default photo viewer (probably the new Photos app). Click this to see a list of options for a new default photo viewer. Assuming you upgraded to Windows 10 from a previous version of Windows, you should see Windows Photo Viewer as an option.
JPEGView is a small and fast viewer/editor for JPEG, BMP, PNG, GIF and TIFF images. On-the-fly image processing is provided - allowing to adjust typical parameters as sharpness, color balance, contrast and local under-/overexposure. JPEGView provides an unobtrusive interface to image viewing with most controls only appearing on mouse-over of the window or the lower section of the window (for image processing controls). It has a simple black-background and an optional full-screen mode enabling you to really look your images without distraction.
Full Frame is a Mac-based image viewer, photo importer and metadata editor with an incredibly clean and intuitive user interface. Released by California-based Inland Sea and available now in the App Store, its potential to speed up one's workflow caught our attention.
With your mouse hovering over an image, a small plus sign will appear in the upper left of the photo. Click on it to expand the view. Once in the single image viewer, users can use the slider at the top to zoom the image in and out, to check for critical focus. Unfortunately, when zooming in and out, there is no display of the percentage you are zoomed to, unlike in Photo Mechanic.
Full Frame is an outstanding option for photographers seeking a powerful EXIF viewer/XMP editor or a quick and easy way to import and rename files. Its spotty Raw support is the main thing holding it back. But at $30, Full Frame is a major bargain compared to Photo Mechanic, which will set you back $150. It is also a much faster way to quickly view and sort JPEG files than Adobe Bridge.
From the site about Viewit:
"OS X native, fast and easy to use image viewer that supports most popular image formats: JPEG, TIFF, PNG, PSD , RAW, DNG, animated GIF and more. Important ViewIt features include: unique, intuitive interface, full screen mode, slide shows, quick image sorting, printing, digital cameras and EXIF tags. Currently includes plugins: convert file format, create web pages, Finder previews, lose less JPEG transformations, shell scripts support, rename sequentially, create contact sheets.
It makes little sense to present/review such an app on a photo site, since these days also phones can output raw files, so almost all photographers, will have some raw files, even if the ones that shoot mainly jpeg.
JPEG Viewer is an application that lets you not only view photos but as well as apply basic edits like resizing and adding text.
