Hi Larry,
sorry - English isn't my native language. What I want to describe:
I'm reading 3d models inside my application. Some old 3DS files have
references to GIF files as texture references. If I understand the
documentation for ImageCache these files should be ignored by
ImageCache. What I do:
bool loadable = false;
try
{
loadable =
Im_ImageCache::GetInstance()->GetCache()->get_imagespec(tmpName, tmpSpec);
}
catch(...)
{
GetCache() is my reference to ImageCache. LibOpenJPEG is linked only
inside OIIO.
FROM my understanding of OIIO documentation get_imagespec should return
false if OIIO could not read the image format (for example a GIF file).
Is this true?
But I don't get false as a return value, I always get the exeption from
j2k_decode.
Best regards,
Patrik

Could you clarify exactly what you mean by: "Now I've got a link to a gif image for
loading. OIIO should ignore it..."
Do you mean that your application is also, separately, using LibOpenJPG on its
own and is holding an open handle of some sort? Of the same file?

Hi all,
I've started using OpenImageIO as a replacement for FreeImage. Now I've got a
problem with LibOpenJPG, and I'm not sure if its an configuration problem or an
OIIO problem:
OIIO is compiled as a DLL with static linking for most of the plugins.
Inside my application I use the ImageCache. Now I've got a link to a gif image
for loading. OIIO should ignore it, but I always got an exception inside
Jpeg2000Input::open (...) in jpeg2000input.cpp:
opj_image_t* j2k_decode(opj_j2k_t *j2k, opj_cio_t *cio, opj_codestream_info_t
*cstr_info) {
opj_image_t *image = NULL;
....
if (id>> 8 != 0xff) {
opj_image_destroy(image);
opj_event_msg(cinfo, EVT_ERROR, "%.8x: expected a marker
instead of %x\n", cio_tell(cio) - 2, id);
return 0;
OpenImageIO.dll!j2k_decode(opj_j2k * j2k, opj_cio * cio,
opj_codestream_info * cstr_info) Zeile 1798 C
Is this a known problem or a problem with my CMake settings?
OIIO is build for VC2010 64 bit debug version.
Thanks for any info,
Patrik
