JPEG 2000 Filetype (2016-10-01)

27 posts in this topic

This plugin loads and saves JPEG 2000 images, superseding the old JPEG 2000 plugin.

The plugin should be able to load and save most JPEG 2000 images, although loading large images may be slow.

The Visual C++ 2010 SP1 runtime is required to run this plugin (x86 for a 32-bit OS, or x64 for a 64-bit OS).

Could you tell us, at least, what a Jpeg 2000 does?

Why is it different and why would we use it?

Nice job null54. Thank you.

I'll flag the old plugin as obsolete and link to this thread - done.

Installation instructions:

1. download the zipped file attached to the first post in this thread.

2. Unzip it.

3. Copy or move the three *.dll files to the Paint.NET/Filetypes/ folder.

4. There may be a conflict between this plugin and the one it superseded. To avoid this you should delete the old plugin - you'll find it in the same folder.

5. Restart Paint.NET.

As this is a filetype plugin it will only show up as additional file extensions in the load/save dialogs.

Superb, thanks for the excellent plugin. Wish Paint.NET would have a plugin store where you just tick which ones you want to downoad/buy as this would be a no-brainer for many web artists. (Thinking eclipse like..) anyhow, excellent plugin and will give it a try now.

Hmmm, still not working for me. I got unspecified errors with the 1.0.0.0 version and now it is now saying unrecognized file type with 1.0.0.1

Cheers

Do you have a link to a file that fails to load?

Hmmm, now it is back to unspecified error. Here is one of the files that is giving problems. From Archive.org:

https://dl.dropbox.c...r_orig_0002.jp2

Thanks for your diligence, not sure why these jp2 files are giving trouble. Some others are fine.

That file loads fine for me, the only thing I can think of is it may be running out of memory.

What OS do you have, how much RAM?

In the "Save configuration" box,

Preview, file size: (error)

After I click on the "OK" button, it says,

There was an unspecified error while saving the file.

Any help with this problem?

Hi,

 

@null54, I was wondering, could this plugin support resolution information in the JP2 headers? I know this is optional, and libs such as openjpeg (or FreeImage which embeds it) do not support this yet.Though, you seem to use the jasper implementation; I've downloaded v1.900.1 source code, and it seems to support resolution information (through the JP2_BOX_RESC and JP2_BOX_RESD boxes defined in jp2_cod.h).

 

 

Or, is there a possibility you publish your plugin's source code?

 

Regards, Olivier

That should be simple enough to implement.

 

Do you have any example files with DPI information?

JPEG 2000 is more standard really. It isn't great, but it isn't changing any time soon..

To clarify, it's the most recent standard to be released by the JPEG working group.  The standard JPEG that Paint.NET saves in is still the more commonly used file format.

Would .jpf compatability be possible?

 

You could try renaming the file extension to JP2 and see if the file loads.

 

JPF is an extension of the JP2 format and the JasPer library used by this plugin does not support the extended format, but some files may work.

Fixed in 1.0.0.5.

 

It appears that the behavior of the DLLImportAttribute's ExactSpelling field differs on the 32-bit vs 64-bit CLR.

The 64-bit CLR searches for the stdcall mangled names when ExactSpelling is true and the 32-bit CLR does not. :/

Now I want to know, wether this plugin is affected or not.

 

This plugin uses JasPer not OpenJPEG.
