[opendx-users] Collect Arrange bitmaps

2001-01-16 Thread Paul Andre
I am working on a MRI viewer and would like to display 3 bitmaps in the same window. But, as I connect my 3 slices (90x130x8bit, 130x80x8bit and 80x90x8bit) to Collect and then to Arrange, I get : ERROR: Arrange: Operation not implemented: transposed images not supported, standard deltas are

[opendx-users] binary output in fortran

binary output in fortran90 with statements like: open (channel_3, file=mesh_xyz.bin, form=unformatted, iostat=ierr) write (channel_3) ((xyz (dir, node), dir=1, Snum_dirs), node = 1, num_out_nodes) work fine in dx-files with a line like: msb binary data

[opendx-users] invalid positions array type

2001-01-16 Thread Sharon Cady
Anybody know of a way to force the invalid positions array which is obtained by Extract to always be given as bytes rather than (which is sometimes the case) integer ? I am doing x/y plots of two fields, and want to plot only points that are valid in both x and y. I believe that the inherent

Re: [opendx-users] invalid positions array type

2001-01-16 Thread David Thompson
When sending something to plot, you should have a set of scalar positions with data values that will become the y. So how do you know if something is valid in y? I think there might be an easier solution that playing with the invalid positions arrays, but I need to know more about what you are

Re: [opendx-users] invalid positions array type

2001-01-16 Thread Sharon Cady
Say I have 2 fields, temperature and humidity (same positions component). Each field initially has its own set of invalid positions, since it independently contains out of range values which have been tagged as such by Include. By saying that I only want to plot points that are valid in x and y,

Re: [opendx-users] invalid positions array type

You can do this with Compute... Since Compute(a+b) returns invalid if either a or b is invalid, just compute a bogus (temp_humidity) field, and then extract the invalid positions from that field and insert it into the original field. Marcus Mendenhall Say I have 2 fields, temperature and

Re: [opendx-users] invalid positions array type

2001-01-16 Thread David Thompson
Since you have two fields both with the same positions and both of scalar data, just run them both into Compute, add the two fields together (a+b) and the result out the other end will have the invalid positions of both fields intersected. You can then extract this new invalid positions and
