koreader v2024.04 android img turning w/b on reflow

[Jindam]

* download "A Delicate Choreography"_ https://library.oapen.org/bitstream/...3111014548.pdf
* search_ Fig. 53: Daddys harem
* go to page containing image or figure 53
* notice image is in colour
* "turn on" **Reflow** to "on"
* image is no longer in colour, however,
it is in white and black
* is this correct?

This is probably because Reflow mode depends on K2pdfopt to process the document, which has b/w as its default output option. To my knowledge, it is currently not possible to change that within KOReader.

I believe that an update to the internal K2pdfopt library is currently in development. When it will be available and whether or not color output will then be supported via Reflow I can't answer unfortunately.

I doubt it's explicitly planned in that sense; that's just an update of the code, but in any case it wouldn't make much sense to add it until such a thing is done.

Presumably a switch doesn't make much sense (other than the global b&w vs color switch already in the settings menu); it'll just need to tap into it.

* did you mean_ screen_ color rendering
* it was enabled

Yes, that's what was meant. The color setting currently has no effect on Reflow mode because Reflow uses a different rendering engine under the hood (K2pdfopt).
