- import ~/summer-demo/summer.tif fails with "unable to read embedded
profile", is this a bug? better err msg would be good
trying to catch errors now, but is it working? not sure
WONTFIX for 7.20
================
- some of deprecated.h repeats stuff we do better in image.h, eg. addr()
should just call IM_REGION_ADDR()
- load 500 jpegs, group, shrink, save
VM use is huge, ouch, could we use a bit less?
