Fuji X-Trans files opening slow

I am the developer of librawFX (https://github.com/lanthale/librawfx) and I am using with this way libraw. Generally all is working well and also the speed is good for reading raw files.

Nevertheless if I open Canon/Nikon file it takes 1-2 s to open the file (max. 3s). Opening a Sigma file takes around 3s. But if I open a fuji x-trans file it takes 15 - 20s.

Do I have to ship some extra libs to get here the same speed as with Sigma files ? Or is it a bug actually that it takes so long ?

Thank you in advance for your help.


I am using "libraw_dcraw_make

I am using "libraw_dcraw_make_mem_image". Maybe this is the issue. What should I use instat ?

dcraw_make_mem_image is the

dcraw_make_mem_image is the last step, applied after all postprocessing steps.

I suggest you to play with quality settings and/or half-size output. Also, OpenMP may help with default quality settings.
