I get this crash too, when loading some textures I created.

[pix_multiimage textures/*.tif 4]

Pd crashes with:

pd: magick/exception.c:948: ThrowMagickExceptionList: Assertion 
`exception->signature == 0xabacadabUL' failed.
Pd: signal 6
pd_gui: pd process exited


I created the .tif files from .png files (that Gem seems unable to 
load), using ImageMagick 'convert 0.png 0.tif' (etc).

$ file *
0.png: PNG image data, 64 x 64, 8-bit/color RGB, interlaced
0.tif: TIFF image data, little-endian
1.png: PNG image data, 64 x 64, 8-bit/color RGB, interlaced
1.tif: TIFF image data, little-endian
2.png: PNG image data, 64 x 64, 8-bit/color RGB, interlaced
2.tif: TIFF image data, little-endian
3.png: PNG image data, 64 x 64, 8-bit/color RGB, interlaced
3.tif: TIFF image data, little-endian

The TIFF files are attached, in the hope that they might be useful in 
analysing/eliminating the problem.  I also tried adding an alpha channel 
to the PNG files and converting again, but have the same crash when 
loading the new TIFF files.


Next I tried converting to JPEG, but that failed in a different way:

I have textures/0.jpg through textures/3.jpg, and I tried sending "open 
textures/*.jpg 4" to [pix_multiimage], and got:

TIFFOpen: /home/claude/maximus/d01234/textures/4.jpg: Cannot open.

And when I try to select textures I get:

error: [pix_multiimage]: GEM: pix_multiimage: selection number too high: 
0 (max num is 0)
error: [pix_multiimage]: GEM: pix_multiimage: selection number too high: 
1 (max num is 0)
error: [pix_multiimage]: GEM: pix_multiimage: selection number too high: 
2 (max num is 0)
error: [pix_multiimage]: GEM: pix_multiimage: selection number too high: 
3 (max num is 0)


Any ideas?  I'm guess I'm misunderstanding something about how 
pix_multiimage expects files to be named, or something?


Gem cvs from a couple of weeks ago, pd-0.40-2


Thanks,


Claude
