Firstly, this command works on Windows command prompt well.

kdu_expand -i /home/tmp/1.jp2 -o /home/tmp/1.tif -region 0.1,0.1,0.1,0.1

In Linux, I get the following error:

The `-region' argument requires a set of coordinates of the form, "<top>,<left>,<height>,<width>". All quantities must be real numbers in the range 0 to 1.

If I remove the -region parameter and run like this:

kdu_expand -i /home/tmp/1.jp2 -o /home/tmp/1.tif

it works on Linux too.

Here is the part of the code which parses the parameter:

 static void
 set_region_of_interest(kdu_args &args, kdu_dims &region, siz_params *siz,
 double &width_fraction, double &height_fraction)
 /* Parses the `-region' argument to see if a reduced region of interest
 is required. Returns the region of interest, expressed on the
 original codestream canvas (no geometric transformations) along with
 the fraction of the full image width and height which are represented
 by this region. */

 width_fraction = height_fraction = 1.0;
 if (!(siz->get(Sorigin,0,0,region.pos.y) &&
 siz->get(Sorigin,0,1,region.pos.x) &&
 siz->get(Ssize,0,0,region.size.y) &&
 siz->get(Ssize,0,1,region.size.x)))
 assert(0);
 region.size.y -= region.pos.y;
 region.size.x -= region.pos.x;
 if (args.find("-region") == NULL)
 return;
 char *string = args.advance();
 if (string != NULL)
 
 double top, left, height, width;

 if (sscanf(string,"%lf,%lf,%lf,%lf",&top,&left,&height,&width) != 4)
 string = NULL;
 else if ((top < 0.0) 
 if (string == NULL)
 kdu_error e; e << "The `-region' argument requires a set of coordinates "
 "of the form, "<top>,<left>,<height>,<width>". All quantities "
 "must be real numbers in the range 0 to 1."; 
 args.advance();

The parameter 0.1,0.1,0.1,0.1 is subject to the brace expansion in Linux shell. You can check it with echo:

$ echo 0.1,0.1,0.1,0.1
0.1,0.1 0.1,0.1 0.1,0.1 0.1,0.1

$ echo A0.1,0.1,0.1,0.1B
A0.1,0.1B A0.1,0.1B A0.1,0.1B A0.1,0.1B

To prevent this behavior, enclose the parameter into single quotes ('...').

kdu_expand -i /home/tmp/1.jp2 -o /home/tmp/1.tif -region '0.1,0.1,0.1,0.1'
