Add DIB file extension

Recommended Posts

At least with Windows 10 you find ".dib" as alternative file extension for Bitmaps. These are rendered as normal bitmap in the Windows Explorer.


Current behavior with PDN 4.0.21:

* open file: extension "*.dib" not shown

* manually choose file: error message "image format unknown..."

* manually rename file to *.bmp: file can be opened without any problem


Windows 10 Paint, Paint 3D (and IrfanView) opens all *.dib as *.bmp - is it possible to add the same behavior to PDN (without installing the following plugin)?

What exactly do you need DIB for? Are you just asking for completeness or do you have some task that makes use of it?


And why would you need it built-in if there's already a plugin for it?

The main point is: a DIB is actually a BMP (you can currently edit it if renaming dib->bmp, use Paint.net, save, rename back) and it therefore looks as only the file filter and the internal recognition by file extension has to be added.

Why should one add an additional extension (that adds code which may have performance/stability issues, isn't updated along the main program) if the main program can handle it without big changes?

Additional: " Some file extensions can also be covered by other plugins" - no/less plugins means no/less conflicts
