Rendering rasters without JAI

[Gabriella Turek]

Hello, I've been trying to get my geotools project to compile and run
on my mac and
everything seems to work OK except for the when I try to render
rasters, as there is very limited
JAI support for the mac (no native library components). Now UDig
seems to do just fine, so
there's obviously a workaround.  I am using JMapPane as the basis of
my code, and that's where
all the rendering happens. Does that mean I have to dig into that
code and rework all the JAI calls,
or is there a quicker workaround?
Thanx
gaby

I think you can install JAI and ImageIO into your mac JRE.

Reading the udig documentation it looks like uDig is making do with what
is included with macosx; remember that uDig is shipping with an old
version of geotools prior to all of Simone's nice work.

Here are the udig docs:
-
http://udig.refractions.net/confluence/display/ADMIN/04+Java+Runtime+Environment#04JavaRuntimeEnvironment-MacOSX

I do remember we used to take a liunux download; and stuff the jars
manually into the macosx JRE; I am under the impression there are
installers to do it for you now... here is a really old set of
instructions to that effect.
- http://docs.codehaus.org/display/GEOT/1+Java+Install
-
http://docs.codehaus.org/display/GEOTOOLS/6+Can+Geotools2+be+used+on+Mac+OS+X

I no several mac osx develoeprs (Jesse, Justin etc...) but so I have not
managed to get a good set of install instructions out of them; Jesse
*is* working on a uDig installer that will update your JRE right now; so
perhaps contacting him and asking to help him test will be the easiest
approach.

Hi Jody, the problem is not installing JAI, I have done that. The  
problem is that it's a partial install, ie you can install the jars,  
but not the OS
dependent libraries which do not exist for Mac OS X. Which means that  
you're doing fine as long as you use methods that do not
depend on those libraries, but you're sunk if you do (we had the same  
problem with a project at my previous job).

I'm not aware of any conscious decision to make gt2 dependent on
any native method of JAI. So, if you can report back what's going wrong,
we'd like to hear.

GeoServer is exercising most of the coverage libraries and we do
ship only with the pure java part of JAI, installing the native
one is optional. Yet, I don't remember significant complaints about
lack of functionality. It's slower of course, but should work fine anyways.

So let us know what's breaking in your case
Cheers
Andrea

Hi Gabriella,

Unless you have an old Mac you shouldn't need to install JAI or
ImageIO.  They come pre-installed as part of the OS (I'm running 10.4
on a macbook and it has both).  The jars should be in
/System/Library/Java/Extensions.

http://developer.apple.com/releasenotes/Java/index.html#//apple_ref/doc/uid/TP30000872-TP30000425

The only JAI prob I've had with Geotools on the Mac was getting
nonsense values from convolution when using anything other than a
minimal kernel size.  I talked about that in a recent thread.  And the
problem was actually fixed by turning native lib support *off* like
this:

Properties p = new Properties(System.getProperties());
if (p.getProperty("os.name").compareToIgnoreCase("mac os x") == 0) {
  p.put("com.sun.media.jai.disableMediaLib", "true");
  System.setProperties(p);
}

This is happening because you lack the "JAI Image I/O library". GeoTools
needs both, JAI and the ImageIO extension:
https://jai-imageio.dev.java.net/

Yes.  Wierd - my machine is a couple of years old (it had OS 10.4.4 I
think when I got it, since patched to 10.4.8) but I didn't have to
install any JAI stuff.  Sorry if I gave you misleading info.

Out of interest what version of Mac OS are you running Gabriella ?

Ooops, you're right I did not have jai-image-io installed. But here's  
the funny thing:
I downloaded it (the linux version, I suppose it doesn't matter) and  
installed it in /System/Library/Java/Extensions but I still get the  
same error message.
I then looked at my classpath and I remember having to add the other  
jai jar files expressly to it
to make my demo work (except for this error).  So I also added the  
jai-imageio.jar file expressly  to the classpath, and I still get the  
error.
I am running 10.4.11 in my PPC powerbook, java version 1.5.0_13

Hi folks,

Regarding this ImageIO / Mac problem - Gabriella and I chatted a bit
further about it off the list.  The error comes from a call in
WorldImageReader.java:

   JAI.create("ImageRead"...

to load the coverage raster from file.  The problem is that the
ImageReadDescriptor class isn't in Apple's version of ImageIO.  I
think on other platforms it is part of the native lib stuff (correct
me if I'm wrong) and on the Mac there are only the pure Java
components of ImageIO.

But a bit of testing showed that Gabriella can read her jpeg file
successfully using ImageIO functions directly.  So would it cause any
problems if that were done in the WorldImageReader class and the
analagous code in the WorldImageWriter class ?

Hi there.

I'm a mac developer for the gvSIG project, which used to install jai_imageio.jar as  discussed in this thread (that is, as extracted from some other platform's distribution). But recenty we found serious side effects: java applets cause mozilla-based browsers to crash.

If you don't put the jar in the Extensions directory but use it in the classpath when needed, you will avoid those problems.

For more details,

Super - many thanks for this info

Hi

Sorry to dig up an old thread but I'm getting this problem on both
windows and a linux. I'm deploying with maven and have the pure java
jars as dependencies (jai_core, jai_codec, jai_imageio).
I've been using geotools version 2.4.4 (possibly the problem has already
been resolved in the development version). Anyway, in each case I can
only perform the read if I've deployed the native libraries. The code I
use is below, I think it's based on code from a tutorial.

ImageMosaicFormatFactory imfFact = new ImageMosaicFormatFactory();
ImageMosaicFormat fmt = (ImageMosaicFormat) imfFact.createFormat();
if (fmt.accepts(dataIndex)){
    ImageMosaicReader reader = (ImageMosaicReader) fmt.getReader(dataIndex);
    coverage = (GridCoverage2D) reader.read(null);
    reader.dispose();
}

Is there a pure java workaround for this?


Cheers Alistair

I also had problems with different configurations of JRE with or without
native support and recorded my findings here:
- http://jira.codehaus.org/browse/GEOT-1862

Near as I can tell the default ImageReader that comes with one of the
JRE bundles is bad; and we do better to make use of the pure java
reader; or we do better to make use of a replacement installed by the
ImageIO extension.
