Hi all,
sorry to bother you again with my issues, but i'm facing another wall I
can't get over:
following the discussion about file streaming, Ii compiled and used
successfully iconvert and maketx to generate files I could stream. For
my pleasyre it worked perfectly... until I switched from CentOS to
windows 7.
We've been trying for two days to compile a working version for windows
without any success. We've tried several tiff versions ( 3.8.2, 4.01,
4.0.2, 4.0.3), and have two main issues:
We cannot use maketx to write tiled tif files. (Initially the
application crashed, we made a fix so it exits correctly and displays an
error message. I'll make another thread to discuss it, and a possible fix)
The error message being 'TIFFWriteTiles failed'. (first call !)
We tried to change the format to generate exr files, and it is working.
We can generate 32bits exr files, and load them back.
With windows we cannot load correctly tif files that have been generated
with CentOS. Colors are all messed up, in grayscale images which are
recogniable parts of the image are missing.
EXR files generated with windows can be loaded with CentOS.
We downloaded a tiff test image with tiles and mipmaps ( the louvre
photography ). It loads correctly on CentOS, but displays nothing using
windows.
Note: in all tests we made, we used the same code, accessing data with
TextureSystem.
Is there another version of libtiff i should use ? Any known bugs in the
tiff plugin i should be aware of ?
