Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. I don't know another way to display and confirm the JXL on this computer, as Photoshop does not support that file format.JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. So as best I can tell, I've created a valid JXL HDR image but neither FireFox nor Chrome is displaying JXL as HDR. I suspect the JXL implementation in these browsers simply does not support HDR at this time, but perhaps they do with other file formats? When I convert my JXL back to TIF, I am seeing an HDR image again. I can see HDR videos on these same browsers, so they display HDR for at least YouTube. The same HDR image after conversion to JXL looks like a 16-bit image when viewed in the browser, it is definitely not displaying as HDR in Chrome or FireFox. My source image in Photoshop (using the tech preview for HDR display) looks awesome and very clearly is HDR (as compared to another non-HDR monitor I've used for testing). I can very clearly see as many as 5 stops above SDR white (typically 3.5 stops under my working settings). Yes, an Apple M1 Macbook Pro (XDR display). AVIF doesn't work for me (IM v7.1.0-42 on Windows 8.1). Running " magick -version" reports " ImageMagick 7.1.0-45 Q16HDRI.", which I believe should support HDR conversions.īeta Was this translation helpful? Give feedback.į:\web\im>%IMG7%magick -size 10x1 gradient: -evaluate Multiply 10 -depth 32 x.jxl Is an HDR-compatible export from ImageMagick not possible? When I reverse it back to a 32-bit TIF, the result is clearly clipped, so I'm pretty confident my AVIF conversion failed. However, when I try to convert using ImageMagic (command line: magick "my source file.tif" - depth 32 "my new file.avif"), the result is a 16-bit channel depth (as reported using: magick identify -verbose). When I reverse convert the JXL back to TIF, I do see the HDR content, so it looks to me like JXL image support in these browsers does not include HDR image content. I've been able to use ImageMagick to convert to JXL, but it shows as clipped (no HDR content) in FireFox and Chrome. Is there a way to use ImageMagick to convert a 32-bit (HDR) TIF into any image format which can still be viewed as an HDR image on any browser?
