Sure I already restarted Pd. I compiled Pd(0.46-7) myself, and Gem is
installed by Pd-DEKEN(https://github.com/pure-data/deken). Here is my
information.

Installed Pd ver on my ubuntu 14.04-3
Pd-0.46-7 (compiled myself)
Pd-0.45-4 (by Ubuntu Repo)
Pd-extended 0.43.4 (manually installed by .deb)
Pd-l2ork 20151230 (manually installed by .deb)
Result with Pd-0.46-7 (compiled myself)
1. $ which pd
/usr/local/bin/pd

2. $ pd -stderr -verbose your-patch.pd 2>log.txt
attatched

The log contains:

verbose(6): backend 'magick' unavailable

As far as I can tell, this means it detected ImageMagick plugin, but couldn't proceed - I don't know why, and the code is a maze of twisty plugin factories that I don't yet understand.  Maybe one of the GEM devs can help you debug this - it might be a problem with how it is packaged in Deken, or a missing library dependency on your system, or something else.

Sorry, and good luck,


Claude

many thanks,
jonghyun

You have to restart Pd for GEM to notice the new plugins.  If you did that
already, maybe there is a conflict between self-compiled Pd GEM and
system-installed Pd GEM?  Please send more information:

$ which pd                                     # should be /usr/bin/pd
$ pd -stderr -verbose your-patch.pd 2>log.txt  # attach log.txt to mail

thanks claude, I installed it by "sudo apt-get install gem-plugin-magick",
but it still can't load PNG. Pd says same as before: only "Image loading
support: SGI jpeg". how to solve it?

thanks,
jonghyun

on ubuntu 14.04 linux, [pix_image] handles only JPEG files. No PNG, No

others. How to load PNG or TIFF files? when I make [pix_image], Pd says
"Image loading support: SGI jpeg"

FYI, on Mac OS X, it handles PNG files, but on linux doesn't. Why
linux can't do that?

Linux can do that, don't worry.  GEM uses a plugin system for image
loaders/savers - probably GEM is distributed with them split out into
multiple packages. Try:

$ aptitude search gem-plugin-

which lists many available to my Debian system, not all of which I have
installed.  I think gem-plugin-magick should be enough to load PNG and
other common formats.
