Hi @Tom Blake, Having double-checked this with QA, they confirmed our support for JPEG 2000 is currently only for J2K and JP2. So this isn't a bug and would be more of a Feature Request to support JPX. I'll get this moved over to Feature Requests

https://jpeg.org/jpeg2000/ Part 2: Extensions Part 2 defines codestream and file format extensions including: multi-component transformations; more flexible wavelet tranform kernels and decomposition structures; alternate quantization schemes; and non-linear point transforms. The Part 2 JPX file format extends the Part 1 JP2 file format to allow: more comprehensive color space descriptions and HDR sample representations; multiple codestreams; composition, cropping, geometric transforms; rich animations; descriptive metadata; and a rich metadata set for photographic imagery. (Opens fine with GIMP.)

The Help lists J2K and JP2 as supported file types, but not jpx. I'm not sure your file format is supported, @Tom Blake. (I can't try it myself at the moment.)

On Mac, Affinity apps simply offer the OS which file types they are capable of opening. The OS then apparently picks the newest version of an app, based on the file type list in /Applications/Affinity Photo 2.app/Contents/Info.plist (for example): <dict> <key>CFBundleTypeExtensions</key> <array> <string>afdesign</string> <string>afpub</string> <string>affinity_photo</string> <string>affinity_designer</string> <string>persona</string> <string>affinity</string> <string>psd</string> <string>psb</string> <string>svg</string> <string>jpg</string> <string>jpeg</string> <string>jpegxr</string> <string>jxr</string> <string>j2k</string> <string>jp2</string> <string>jxl</string> <string>png</string> <string>wdp</string> <string>hdp</string> <string>tiff</string> <string>tif</string> <string>gif</string> <string>webp</string> <string>lfp</string> <string>eps</string> <string>ps</string> <string>pdf</string> <string>ai</string> <string>fh11</string> <string>fh10</string> <string>bmp</string> <string>exr</string> <string>hdr</string> <string>crw</string> <string>cr2</string> <string>cr3</string> <string>nef</string> <string>pef</string> <string>raf</string> <string>dng</string> <string>mos</string> <string>kdc</string> <string>dcr</string> <string>arw</string> <string>nrw</string> <string>3fr</string> <string>ari</string> <string>srf</string> <string>sr2</string> <string>bay</string> <string>cap</string> <string>iiq</string> <string>dcs</string> <string>drf</string> <string>k25</string> <string>erf</string> <string>fff</string> <string>mef</string> <string>mdc</string> <string>mrw</string> <string>orf</string> <string>ptx</string> <string>pxn</string> <string>r3d</string> <string>raw</string> <string>rw2</string> <string>rwl</string> <string>srw</string> <string>x3f</string> <string>afmigrate</string> <string>afsignal</string> <string>abr</string> <string>tga</string> <string>afextensiondocument</string> <string>heic</string> <string>gpr</string> </array> <key>CFBundleTypeIconFile</key> <string>PhotoDocIcon</string> <key>CFBundleTypeName</key> <string>Affinity Openable</string> <key>CFBundleTypeRole</key> <string>Editor</string> <key>LSHandlerRank</key> <string>Alternate</string> </dict>

Odd. For me the plugin & app are completely independent of one another. In fact, I did not open the app until I had played around with the plugin for an hour or two. So far, the only problem I have found with it is the app version chokes when I try to open a jp2 file with it. Other than that & the less than user friendly UI, the only issue I have seen with either is it can be slow to apply a filter, but not more than 1-3 seconds so not too bad.

Issue solved, thank you all for the super fast and deep analysis!!! my export options were the default digital-small size with no altered options was tested in PDF Xchange Viewer, WPS, and Acrobat Reader did so for future reference, I upload the original my first "erroneous" attempt, and a second version with PDFs including layers @Hangman before posting this topic I read your answer to another, similar topic. Now, + @lacerto it is much more clear to me how "Layers" work. ("3rd degree" test?! - respect!) Thank you ALL! jp1.afdesign jp1.pdf jp2.afdesign jp2.pdf

Exporting with a fully transparent background via the alphachannel has to be supported by the respective bitmap file format. Usually the common plain JPG format doesn't support this (the alphachannel), only advanced Jp2/Jpeg2000 variants of JPEG! - For Affinity you've to use instead PNG/GIF for exports which do support this!

FWIW, all 3 Affinity apps can open it, but in the Mac version of APub it can't be opened from File > Open (it is greyed out) but like with other raster image formats APub will happily open it via the Finder right-click "Open with" option. The same is true for any file I could open in the Mac Preview app & from it used Export to the JPEG-2000 format, even GIFs, PSD's, anything else Preview app can open. This gives the export a jp2 file extension. Also seems to work with JPEG2000 files with the j2k or jpf extension & maybe others -- basically anything I tested that on the Mac has a "Kind" of "JPEG 2000 image."

One more: https://convertio.co/jp2-jpg/ worked about 15 minutes to convert to jpg and came up with the attached.

Main jpylyzer results: statusInfo: True isValid format="jp2": True However, products.groupdocs.app/viewer/jp2 can't open the file, "Server failed to process the request".

Hey @eWeinhold, I tried to open your JP2 file and got the same result as you. Then I tried some sample 16bit JP2 files from the web, and they opened just fine with AP. Maybe there's a problem with your file???

¯\_(ツ)_/¯ The Bug is still there.... 16Bit jp2 support is still Broken on Windows AND Mac Versions

Affinity Photo is not able to correctly open 16 bit jp200 files. It opens them, but the image is missinterpreted and covert with random noise. This error appers on WINDOWS _and_ MAC Versions. 16bit-jpeg2000-picture.jp2

Affinity can not read jpeg2000(jp2) created by SilverFast 8. Only "sandstorm" is shown like broken TV. The image is a confidential material, so I sent it to affinity@serif.com.

Basically I can write a picture tag as per: <picture> <source srcset="img/image.webp" type="image/webp"> <source srcset="img/image.jp2" type="image/jp2"> <img src="img/image.png" alt="woof"> </picture> But also it's also just a matter of time until you upgrade. I would wager you're not going to be on Catalina in 2030, and I've been in this business long enough to care about the long game..

In APub on Macs, File > Open in all 3 personas greys out all jpeg, jp2, png, gif, tiff, etc. files -- I think this includes all pure raster file formats.

Yes - I realized that Silverfast has a config option to add one of a couple of grayscale profiles to the file. So, tried that: TIFF no profile: AP adds a D50 profile and the image looks good TIFF w/profile: AP uses the profile and image looks good JP2 with OR without profile: assigns RGB profile and image is random Example with generic gray 2.2 profile attached. AP v 1.8.6 Thanks! Test-jp2-prof.jp2

Hi @rseals, Welcome to Affinity Forums I believe we already have a similar issue logged but do you mind attaching a sample jp2 from Silverfast to check and add to our report (or fill a new one if none exists) please? Thank you.

Hi - I'm scanning B&W negs from a flatbed in 16-bit using Silverfast, and saving them as jp2. Opening them Affinity Photo results in a warning that it is being assigned an RGB profile because none is assigned; the resultant image is B&W noise. What am I missing?

Firstly, thanks for the reply. I've not seen a good 16bit file format where the images don't take enormous amounts of drive space. JPEG2000 was the best compromise as my scanner software only supports JP2 and TIF output formats in 16bit. I guess a JP2 to TIF conversion will suffice when I need to work the images (which is what I'm doing at the moment with a family photobook). I actually purchased Affinity Photo without first using the trial. My bad for sure but my Photoshop version is getting a little old and doesn't support the raw files from the camera. A time will come when I'm done with the JP2 files for photobooks and this limitation won't phase me.

Hi! Thanks so much for your response. I'm attaching three scans to give you an idea of the type of photos I'll be working with on this project. One is an agricultural field, another is a portrait, and a third is a group portrait. Basically I want to photos to stand out and be as clear as I can make them. I'm looking for suggestions for which tools/settings/filters I should be experimenting with to make and/or what tutorials I should watch to make that happen. I'm afraid I don't have enough of an eye/the technical vocab to describe in more detail what specific effect I'm looking for, so I'm hoping someone can give me some ideas.

I'm new to Affinity photo, and more in depth photo editing entirely for that matter. I'm having an issue with the HSL adjustment not showing the full wheel, only the blue spectrum quarter (see the attached image). I've tried applying the layer from the different menus and always have the same problem and cannot find a way to change the HSL adjustment window layout. Any help or thoughts would be greatly appreciated (I'm running Affinity photo on a Mac, if that makes any difference)! Screenshot 2020-05-18 at 16.42.05.jp2

Hi, I ran unto an odd Bug. Jpeg2000 files with 16bit are opened but rendert wrong. They should look like this: 8bit jp2 files are imported correct though they are imported without the alpha Chanel :( Sample Files: https://www.dropbox.com/t/PTG8RWGO2NGwxCcf http://www.lichtsch.eu/affinity_photo_jp2_bug/jpeg2000_16bit_lossless_with_alpha.jp2 http://www.lichtsch.eu/affinity_photo_jp2_bug/jpeg2000_16bit_lossless_without_alpha.jp2 http://www.lichtsch.eu/affinity_photo_jp2_bug/jpeg2000_8bit_lossless_with_alpha.jp2 http://www.lichtsch.eu/affinity_photo_jp2_bug/jpeg2000_8bit_lossless_without_alpha.jp2 the Files are created with Blackmagic Fusion using the ffmpeg extension so i guess it would also apply to any files that use the ffmpeg or openjpeg 2000 library best regards, Elmar

Please can you make a post about this in questions with a sample that does not work as JP2/JPF is newly added and may need some tweaks.

Thanks, it is the file that I cannot place in Publisher. SD_02_T33_6328_U2_X_EC_90.jp2
