There is certainly slight movement of some structures, but my impression is that it is not nearly as severe as the dramatic shift that one sees in Slim, and not...

@hackermd @Punzo there is an update on this issue at [https://github.com/openlayers/openlayers/issues/12768#issuecomment-1030463105](https://github.com/openlayers/openlayers/issues/12768#issuecomment-1030463105)

I can't use Homebrew because it conflicts with MacPorts. So I tried the static build approach that you pointed to, and provided it with jpegsrc9c as well as the other...

Since this is a matter of API design and consistency, and there is no simple answer, I don't really have anything to add beyond what was already discussed in "https://github.com/pydicom/pydicom/pull/1570"....

Thanks for the quick response - yes, since the ".90" transfer syntax is for mathematically "reversible" encoding, the color transform has to be lossless too, i.e., YBR_RCT, not YBR_ICT, since...
