To illustrate my issue with the missing image-processing routines, first
look at my existing J 8.04 running in jconsole:
load '~addons/ide/qt/qt.ijs'
readimg_jqtide_
3 : 0
if. m=. wdreadimg (utf8 ,y);wh=. 2$2-2 do.
d=. _2 ic memr m,0,(*/wh,4),2
wdreadimg 2#<<0
(|.wh)$ fliprgb^:(-.RGBSEQ) d
else.
0 0$2-2
end.
)
$dir '*.jpg'
195 5
3{.0{"1 dir '*.jpg'
+------------------+--------------------+----------------+
|10HumanFigures.jpg|10pctHaveDisease.jpg|5-point ring.jpg|
+------------------+--------------------+----------------+
fsize '10HumanFigures.jpg'
116279
img=. readimg_jqtide_ '10HumanFigures.jpg'
$img
157 522
Compare this with J 8.06:
JVERSION
