note to self - added a bug report describing the reason. it's a corner case 
when GDAL's ecw libs are in the library path as well.

i will try to compare both implementations or create a barebone gdal image 
loader to exclude JAI issues, maybe the lag is something we can fix on our side.

on the first glance i would agree. are there any other OS softwares according 
to you're knowledge that already ship these binaries. that would be assuring to 
know.

ok, checked it. works instantly w/ the latest snapshot. some further 
investigation (5hrs of digging ;) showed

A) make sure you use or enforce a 32bit java in the start batch.

B) make sure to _not_ copy GDAL support to lib/native. it contains the same but 
incompatible dll files like the ECW support, but is preferred in the library 
path leading to 'procedure not issues'

C) if that doesn't work, also make sure you have MS C-runtime 2008 installed.
  https://www.microsoft.com/en-us/download/details.aspx?id=29

if that still doesn't work please send the complete start log. openjump.log or 
copy/paste cmd terminal output.

..ede

PS: not sure how to deal with this. switching java.library.path's before 
loading the dll's might work. will have to have a look at it. Jukka can you 
please test the performance differences for ECW/JP2 between GDAL and ECW sdk, 
so i can make an informed decision if it is worth the effort to make both work 
simultaneously?

PPS: that's the german error, after exposing it w/ some additional logging (OJ 
r5068 w/ '-v debug')

yeah, i guess we can keep it because of it's small footprint, but as we are 
moving into a x64 world, it will not run there anymore. 

will have to have a look why it doesn't activate anymore. ..ede

still better than the native ECW reader in PLUS, which is limited java 32bit on 
MacOSX and Windows. as far as i am aware there is no 32bit java avail anymore 
for MacOSX.

on Linux and MacOSX users may install GDAL in the system and that should work 
as well if we deliver it to be placed under lib/native.

Re: [JPP-Devel] How to activate ECW/JP2?

2016-10-07 Thread Rahkonen Jukka (MML) 
Hi,

Mail reason for potentially keeping the ECW/JP2 driver: it is faster. At least 
I am remembering it was fast and therefore I tried to test it again. There is 
rather a long lag in opening JPEG2000 images through imageio-ext + GDAL while 
with native ecw binaries the initial opening is very fast.  And the size of the 
ecw binaries is about 3 MB only.

About six terabytes of good test images with CC-BY 4.0 license are available 
from http://kartat.kapsi.fi/files/orto/etrs-tm35fin/. They have 12000x12000 
pixels in one tile and OpenJPEG driver can't open them but ECW/JP2 can.

remember we only provide  Win and Linux distros - no MacOSX

Hi,

I am running r5052 Plus with jre8, 32-bit. I guess that I should have ECW/JP2 
support now, but log from the startup says that native ECW/JP2 libraries are
