Re: [NTG-context] names of cached images

Hello again, likely a bug and one question. 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? Thank you, Jano On Wed, Jun 9, 2021 at 3:23 PM Jano Kula wrote:

Hello list,

usingconversion=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? sure, something like that is always intended; it's an md5 of a hash of all relevant parameters so that when you change one (say the resolution) we now that we need to update

Thank you, wiki updated. J.
