[Openexr-user] Woen't Compile no matter what.

[Thomas Lock]

Hi Everyone

I would like to expose the reading and writing of EXR files
to other languages that i use, but nothing i have tried works as of yet. So
here is my problem. I'm using Visual C++ 2005 EE. As i am still pretty new
to C++ what headers do i need to call, i'm just guessing cause i can't find
a single document that tells me this. All i want to do is be able to read
and write Rgba files for now, and make it a simple as possible.

my code for reading. Writing is simple the reverse function of this.

extern "C" void WINAPI writeOpenEXR (char *filename, int width, int height,
float* Bits128)
{
using namespace Imf;
using namespace Imath;

int i=0;
const char fileName[]=&filename[0];
int bitcount=width*4*height;
int LineWidth=width*4;
Array2D<Rgba> p2 (width, height);
for(int h=0;h<height;h++)for(int b=0;b<width;b++)
{
i=h*LineWidth+(b<<2);
p2[b][h].b=half::half(Bits128[i]);
p2[b][h].g=half::half(Bits128[i + 1]);
p2[b][h].r=half::half(Bits128[i + 2]);
//Still have to fix alpha to be precalculated but don't care about
that at this time since i can't do anything yet.
p2[b][h].a=half::half(Bits128[i + 3]);
}

// ALL CODE FROM THIS POINT ON JUST CAUSES APPS TO CRASH TEST BY REMING
OUT THE LAST THREE LINES
RgbaOutputFile file ("c:\foo.exr", width, height, WRITE_RGBA); // 1

//EVEN WHEN THESE LAST FUNCTION ARE REMOVED IT STILL FAILS
file.setFrameBuffer (&p2[-height][0], 1, width); // 2
file.writePixels (height); // 3
}

Thomas, we haven't really vetted the code for Visual Studio 2005 yet,
but that's part of our upcoming release. Other people have reported
issues with it, too, so it might not be anything that you're doing
wrong.

We'll be preparing the new release in the next month or two.

Can you try your application with VS2003 in the meantime?

thanks

Hi all,

Hope this isn't too frivolous but I am looking for a general purpose
image viewer that supports exr as well as the other common image
formats. Anything out there I have missed?

Thanks,

I don't believe there's one out there yet that supports OpenEXR ...
exrdisplay won't do the trick?

On a slightly related note ... has anyone got magic numbers (for use with
file(1)) for EXR images?

Hi all,
Hope this isn't too frivolous but I am looking for a general purpose
image viewer that supports exr as well as the other common image
formats. Anything out there I have missed?

from ImfHeader.h and ImfHeader.C:


//
// The MAGIC number is stored in the first four bytes of every
// OpenEXR image file. This can be used to quickly test whether
// a given file is an OpenEXR image file (see isImfMagic(), below).
//

const int MAGIC = 20000630;



bool
isImfMagic (const char bytes[4])
{
return bytes[0] == ((MAGIC >> 0) & 0x00ff) &&
bytes[1] == ((MAGIC >> 8) & 0x00ff) &&
bytes[2] == ((MAGIC >> 16) & 0x00ff) &&
bytes[3] == ((MAGIC >> 24) & 0x00ff);
}

Here's the entry in /usr/share/misc/magic on my machine:

The following viewers support OpenEXR. Most likely there are more.

Commercial

* framecycler (http://www.framecycler.com/)

* P3dO Explorer (http://www.senosoft.com/softp3do.php)

* rv, a new image viewer from from Tweak Films, supports OpenEXR;
I don't know if the product has already been officially released.
You may want to contact Tweak (ttp://www.tweakfilms.com/).

Free

* KSquirrel (http://ksquirrel.sourceforge.net/)

* possibly Gwenview -- "Gwenview can load and save all image formats
supported by KDE" (http://gwenview.sourceforge.net/overview)

As far as I know, newer versions of Quicktime and OS X support
OpenEXR, so Quicktime viewers and viewers that use Apples' image I/O
frame work should be able to display .exr images.

If these use the kimgio plugin I wrote, then it'll convert to a QImage, which
is 8 bit per channel RGB (and you can't vary the parameters in the
conversion).

However krita (image editting / painting application that is part of KOffice
1.5) can read, edit (in 16 bit) and write EXR images. Well worth a look if
you have a suitable operating system (Linux or other unix, including Macos, I
think) and are looking for a free (as in freedom, and as in free of cost)
tool with some very useful capabilities.

Thanks Florian,

I had come across P3Do in some further googling, I also found XnView
which seems to work nicely. I will definitely look at rv and the free
ones too, they always fit nicely into the budget.

Eric,

Which version of XnView supports EXR in the meantime? We use that all over
our facility ...

xnview has support in it for the last 2 years I believe.

We've been using it for at least three years, and are pretty current
(1.68) and it definitely doesn't support EXR.

1.68 is 2.5 years old, there have been 8 releases since then.

No idea why it's not on the main page, but it is supported for read
only, not write:
http://perso.orange.fr/charries/xnv/extensions.html

I thought I saw a post from you on the xnview forum in the fall about
gamma issues with exr. Maybe not.

Yep, I am viewing exr's in xnview 1.82.4 at this moment. Exr's are Half
float Zip (16 blocks) and view fine. Haven't tried throwing any other
flavors at it yet.
