pictd

89 words on

Some manual pages just create more mystery than they resolve. For example the one for pictd:

NAME

pictd — general helper tool

SYNOPSIS

pictd

DESCRIPTION

pictd is a helper tool for the Cocoa frameworks.

There are no configuration options to pictd. Users should not run pictd manually.

Strings like Unable to register connection for PICT renderer. or _NSPICTRenderer in the tool suggest that it is related to handling old-school PICT images. But it’s not really clear to me what causes the tool to be launched.

Just being curious…

QuickDraw was not ported to be 64-bit clean, so I imagine this gets launched in 64-bit Cocoa when you try to render a PICT.

QTKit does something similar to run 32-bit codecs in an external process.

That sounds like a very good explanation, thanks. I’ll try to keep an eye on which app might need this. I.e. which apps except httpd and iScrobbler actually are 64bit.

I am starting to be fairly sure that iScrobbler launched the pictd thingy. When hovering over its icon in the menu bar the process seems to be launched. I think iScrobbler is supposed to show album cover art when doing that (doesn’t work for me though).

Thinning the binary with lipo to remove the x86_64 architecture (what would be the benefit of having a 64bit binary for such a small utility anyway?) avoids launching of pictd. (I still don’t see any images appearing, but perhaps that’s just some sort of other bug.)
