Hello, A few days ago I posted about problems with ReadImage and WriteImage in the OpenDX 4.1.1 Cygwin version and I did not see any answer in my box (possible e-mail problems at my Office) or in the mailing list archive. I made new tests on ReadImage and WriteImage with rgb and tiff images and I have now a better idea of what my problems could be :
1. Reading sample rgb and tiff images in /usr/local/dx/samples/data : no problem to read these images from the /usr/local/dx/samples/data directory (colorado.tiff and imide.rgb), but I cannot read copies of these images when they are put in a directory lying in /cygdrive/c where my own workspace is. Here are the errors when reading the copies from /cygdrive/c/... : * with imide.rgb : "Bad parameter : cannot read (h=240 x w=300) sized image from file". But the size of the imide.rgb has been recognized ! * with colorado.tiff : "Invalid data : C standard library call, read (), returns error" 2. I used my own net with WriteImage to produce rgb and tiff images in my own directory lying under /cygdrive/c : I can read my rgb image from where it has been saved in my workspace, but I cannot read the tiff image saved in the same directory. Reading the tiff image returns again the same error as above. "Invalid data : C standard library call, read(), returns error" I guess that I may have a problem with environment variables. Here is my installation : * directory C:\cygwin mounted as / * OpenDX 4.1.1 Cygwin binaries installed in /usr/local/dx. No special variable is set, and everything seems to work well with the default variables from the dx script, except ReadImage and WriteImage. * My work space is under C:\(default MS name for user directory, with spaces !) and can be accessed through /cygdrive/c/..... Please could anybody help me to solve this environment problem ? Thanks in advance.
