XnView Software

Hi!
I'm new here and i'd like to develop the addon library to meet my personal need.
I usually archive my picture files via iso disk image.
For me, here's a lot of advantages to use iso disk image format as archive format, such as:
1. Read only. i did not want my stored picture files somehow been accidentally changed.
2. Fast seeking speed. read pictures from iso disk image is almost as the same responsive as stored on hard disk natively.
3. Easy management. like many other archive formats, packing multiple pictures into one archive file is easy for managing and transfer.
And i know it may not be a very common need for users, so i decide to develop a relative addon for iso disk image format support myself.
So could you please provide some header files for developing for additional archive format support? thanks!
like the function defination of ACEReadArchiveData...
Much thanks for the help!

you have the format SDK here

Hi, this SDK seems intended for extra image format support, not for archive format types like zip, rar, etc.

oh sorry, there is no sdk for archive

Oh, is there any chance i could add support for extra archive formats? XnView is relly the best image viewer on the market and i wish to write addons to make it stronger

XnView uses libarchive

Sorry, i means xnview mp. does xnview mp uses libarchive as well?

i means XnView MP

Thanks! that was an exciting news because libarchive supports ISO image format natively.
There's only one problem left, xnview mp does not recongnize *.iso file extension, if i rename my *.iso file's extension to *.zip, xnview mp could open my iso disk image file with out any problems. So is there any settings provided to make xnview mp recongnize such archive format like *.iso that supported by libarchive? I've tried to directly open my *.iso file with xnview my but with no luck, i have to manually rename it to something like *.zip

you can add iso in Settings>Custom filter

Thanks for the assistance, now it works with iso files perfectly.
This software is really mind blowing to me.
Thanks again for creating such awsome software!
More interestingly, i know this software from chat-gpt's recommandation

Hi, I've found another minor issue during daily use:
When I set image to fit window and I zoomed the image after, zoom out and zoom in the image will not able to make the image to fit the window again ,except manually set the image to fit the window again.
Is there anyway to workaround it? It's minor to me so its ok if there's no possible solution at the moment to fix it, thanks!
