The offending code is probably this, from addons/media/imagekit/imagekit.ijs:
NB. conditional flip of bytes
set_cflip=: 3 : 0
if. IFJA do. RGBSEQ=. RGBSEQ_j_ else. RGBSEQ=. RGBSEQ_jqtide_ end.
try.
if. RGBSEQ do. cflip=:|."1 else. cflip=:] end.
catch. smoutput IFJA{::'Requires JQT';'Requires JAndroid' end.
' '
)
set_cflip''
On my machine, cflip is |."1 and this gets used when encoding rgb data
for viewmat.
Anyways, you could work around this by predefining RGBSEQ before
loading the script.
I hope this helps,
