I was referring to this post about Preview Handlers for other formats:
"old version had working preview handlers for cb7 cbt cbr cbz epub mobi fb2 fb2z … for all supported formats"
So I’m just wondering if the actual “handlers” (dlls???) are floating around here or can be collected from other open sources and resurrected into a separate Handler Installer.
I understand that this Handler Installer doesn’t qualify as “portable” in that it writes to Registry to enhance Explorer. But an UNinstaller could be included to clean the system of these handlers (in the same way I can easily uninstall CBX Shell and Mobi Handler with common Windows uninstallers). …so maybe I’d call it “transportable.”
The same handler installer would be helpful for installed version of Sumatra (forgotten during Sumatra install, handlers get messed up in new Sumatra builds or handlers get messed-up by other program installs).
The whole thing could coexist as a separate “eBook thumbs” installer from Sumatra in the same way Sage Thumbs exists separate from graphics programs. I’ve been researching this around the web for a while and ask here because it seems that a reasonable collection of Handlers existed in Sumatra source at one time and Sumatra itself isn’t updated often with feature requests.
Sadly, I’m only just learning how all this works (though I make and use vbs, bat and reg files to add & remove functions)…just see that the pieces seem to be out there and a simpler, more cohesive way to get eBook covers in Explorer seems doable.
Is it a matter of collecting up the dlls & making vbs, bat and/or reg file to register them and add ShellEx entries in the registry??? (I get clues from notes in Alissa’s MobiHandler)
Does OLDER Sumatra source have thumbnail handler dlls other than PDF as suggested in post link above (its not obvious to me when digging thru various source zips)? I see things like BUILD_DJVU_PREVIEW, BUILD_EPUB_PREVIEW, BUILD_MOBI_PREVIEW, BUILD_CBZ_PREVIEW in rel3.1 pdfPreviewDll.cpp and get curious.
