Hello list,
using conversion=gray.pdf in lmtx the cached images' names have some string
in their name. I thought it's a name of random sequence of luatex cache,
but the string is the same on other machines and I don't know, where it
comes from. mkiv used to have m_k_i_v_ string there.
hacker.pdf = source image
hacker_jpg_c60ccda70ef92e32d7a6334f31c23259.gray.pdf = cached linux
hacker_jpg_c60ccda70ef92e32d7a6334f31c23259.gray.pdf = cached win
MWE
\starttext
\externalfigure[hacker]
[cache=./,
conversion=gray.pdf]
\stoptext
Is it intended behavior?
Thanks,
Jano

Using this code with lmtx: \starttext \externalfigure[mill][width=40mm,cache=./first,conversion=gray.pdf] % mill... \externalfigure[mill][width=40mm,cache=.,conversion=gray.pdf] % m_k_i_v_mill... \externalfigure[mill][width=40mm,cache=./second] % no visible caching \stoptext *First two figures* Chached image in the ./cache subdirectory has a lmtx name without prefix, the cached image in the current directory has mkiv syntax with m_k_i_v_ prefix. *Third figure* The images are cached to a specified directory, only when some conversion is used. I'd like to cache images without any transformation. Is there any conversion which doesn't alter the figure, just caches it? Is new conversion type needed? Or is there other way to force caching without conversion?

What is the benefit of caching (i.e., simply copying the file to a different directory) when there is no conversion?

Images don't change, changed ones have different ID. Encapsualating jpgs into pdfs might be the right conversion, because pdf inclusion is fast, right? So I probably answered myself: write a conversion jpg -> pdf without any changes to the image.
