Hi MareroQ,

Thanks!

I have been investigating and it seems a little more of an issue than I originally thought. The problem is that during compilation of file-apng.c, the datadir is passed in and the ui_file location gets sort of hardcoded into file-apng.exe. If you have access to strings and you examine file-apng.exe then you will see the above location in the executable file. I will continue to investigate whether I can make the exe location independent. This will take time since I have to figure out how the authors coded the whole shebang.

In the meantime, if anyone is interested to use apng, you will have to do what MareroQ did (for 32 bit). For 64-bit check the error and create the appropriate location.

BTW, the "strange" location is my development environment - separate for 32-bit and 64-bit.

Sorry for the "inelegant" solution for the time being.

Thanks,
Partha

i had a update.
change load plug-in-file-apng.ui from user-specific GIMP settings plug-ins directory
"settings/plug-ins" on my build or ".gimp-2.7.3/plug-ins" on Partha's build.

In my build I changed it this way:

ui_file = g_build_filename (gimp_plug_in_directory(), "plug-ins", "file-apng.ui", NULL);

Thanks Partha and Mr. Q it works excellent now.

Hi JamesH & MaxSt,

That was my first try since that is how file-png.c is set up. However, I am still getting GTK errors. You will notice this on a non-developmental machine away from your own machine where you develop.

Using strings, can you check the location coded into fine-apng.exe?

Thanks,
Partha

Edit: Too early in the morning- should have read more carefully.

The file-png.c uses gimp_data_directory() and you can still relocate. So, I will try you solutions and recheck.

Hi JamesH,
You have entered the code - unfortunately I do not know how to use it?

MareroQ,

He is saying to change the code in file-apng.c and recompiling.

Partha

compiled version is here

Any hope for a more user friendly version of this cool plugin (more integrated with the export dialog )?

The problem is that using the saving dialog (in gimp 2.7 the export dialog) as usual, try to save a apng just adding a .apng postfix to the name (as "image.apng" ) lead to error message (unsupported file type ) and failure

the solution is to use instead a more hidden option in the export dialog , but that is not too user friendly, many will just get up after the error message

Instead would be nice if just adding "apng" to the image name in the main "export" dialog would open the apng-plugin dialog

If you use that path PC it works very nicely.
Just place Parthas "plug-in-file-apng.ui" in this directory tree you can create it yourself.
C:\win32\msys\local\share\gimp-apng\ui\plug-ins
The hard coded exe file looks for it there to build the user interface for the animation export dialog.

my comment was about a older version i will try this

I think Partha is going to re-compile it to work in the ui directory tree.

Hey Rod,

I am going to give it one more try.

Can you test the attached version? For the sake of completeness, all the files are included here.

The installation is same as before:

Installation:
1. Copy the dll file to the Gimp-2.7.3\bin directory (typically c:\Program Files\Gimp-2.7.3\bin)
2. Copy the exe file to the Gimp-2.7.3 plugins directory (typically c:\Program Files\Gimp-2.7.3\lib\gimp\2.0\plug-ins)
3. Copy the ui file to the Gimp 2.7.3 ui directory (typically c:\Program Files\Gimp-2.7.3\share\gimp\2.0\ui\plug-ins).
4. For the time being, rename the png plugin to something else (typically found at c:\Program Files\Gimp-2.7.3\lib\gimp\2.0\plug-ins), for example file-png.old.
5. Restart (or start) Gimp.

PC, for the portable version, you can simply do the above.

maybe you can try my compiled version.
it no need to delete orig file file-png.exe
save file, just type file name with the extension apng

Partha it works excellent!

Thanks!




But can we just place the DLL and exe files in the user/gimp-2.7/plugins folder?
Just to make for easier install?(especially for future updates)

So, you didn't have to create the "strange" directory as before, correct? Matter of fact, can you delete that directory and restart Gimp and make sure that APNG is still working?

Well, you can't place them all in plugins folder since they are not plugins.

I personally think that the DLLs should go in the main bin directory since that's where all the DLLs are. In the future when I build Gimp, you will not need the DLL anyway, so don't worry about.

You have to place the UI file in the UI directory since that's the directory structure currently used for PNG and GIF and probably other future UIs unless the directory structure changes again.

Thanks!
Partha

I took the liberty of taking the ui file out of the strange directory before i started Gimp and it worked.
What i actually did was remove the old dll, and exe, and removed the ui file from the strange directory and placed those all on my desktop.Then i followed your install instructions for the new package, and started Gimp.I then loaded Mollys apng file as an png-apng image then exported it as an png-apng with a different name.

Worked fine.

Thanks again.

I just wanted to mention again that i did have to overwrite an existing libpng15-15.dll the first time i downloaded your package.It didn't do any harm to any other plugins (they all seem to work still), and i have no idea why it was there.

If i have any future problems i will let you know.

For XP 32bit location "ui" is still different than the specified c: \ Program Files \ Gimp-2.7.3 \ share \ gimp \ 2.0 \ ui \ plug-ins.

Version Partha:
This is a development version of GIMP. Debug messages may appear here.
Error loading UI file 'C:\Program Files\Gimp-2.7.3\lib\gimp\2.0\plug-ins\share\g

Standardization also requires naming - file *.png (Partha) or *.apng (JamesH)?

Please check the C:\GIMP-2.7\settings/plug-ins folder.
Is there have that file.
Thanks.

Attn: JamesH,
Should the plug-in-file-apng.ui be in gimp-2.0-ui-plug-ins folder
OR
gimp-2.7-settings-plug-in folder
I have it in 2.0-ui-plug-ins and I don't get the (Save as Animation) in the dialog box to save it as a png (apng) extension.
