0 Replies and 2255 Views Different behavior IDL Runtime versus Development environment  2255  0 Started by  Deleted User Hello everyone, I encountered a problem regarding different behavior of the IDL runtime versus the IDL development environment. This problem can be best explained using the following example code: pro test_iplot iplot, indgen(10) res = dialog_message( 'Back from iPlot', /INFORMATION ) end When I create an executable (.sav file) from this routine and run it within idlde, iplot is started and after this has been initialized, the dialog_message statement is executed. When I start the ...

0 Replies and 2102 Views IDL 6.0, Object Graphics - Aspect Ratio Problem  2102  0 Started by  Deleted User I'm creating a hemispherical model using object graphics that is capable of being rotated, translated, zoomed, etc. When the window dimensions are square, the hemisphere is spherically shaped. I want the final aspect ratio to be 4:3 - when I implement this, the hemisphere becomes squashed. I tried to scale the model in the x-direction to look square again, but then the problem is that the trackball rotation from bottom left to top right makes changes the model from spherical to footballish. ...

1 Replies and 1897 Views PCOMP explanation  1897  1 Started by  Deleted User Hi I am doing some Principal Component Analysis with PCOMP. I haven't found the on-line help of much use. Probably because they seem to use a strange nomenclature than that I am used to in PCA. Does anybody have any links to tutorials or similar where PCOMP has been used and explained in more detail than the online help Thanks Russ

0 Replies and 2030 Views idl and hdf5 (opening dataset)  2030  0 Started by  Deleted User Hi there I'm having trouble opening a dataset in IDL5.6 and IDL6.0. IDL recognizes the file as HDF5 (H5F_IS_HDF5), successfully opens the file (H5F_OPEN), and even gives me the correct information about the datasets in the root group (H5G_GET_NMEMBERS, H5G_GET_MEMBER_NAME). However, opening a dataset in this file (H5D_OPEN) fails, with this error message: H5D_OPEN: dataset not found: (67108864, 'Density') I suspect the problem is due to incompatible versions of HDF5. IDL's library (i...

1 Replies and 2224 Views Using iTools for batch processing  2224  1 Started by  Deleted User I am looking for a way for using the iTools for non-interactive (batch) proccesing. The idea is to use for example iPlot in batch mode to produce a plot, save it both as an image (e.g. jpeg)as well as in *.isv format. If needed a user can later costumize the plot by running iPlot in the interactive mode and openening the *.isv file. Another application is to use iPlot to create an iPlot in a specific layout and save it to *.isv file. Later the batch mode may be used to add or modify the data, r...
