Hi all,
my aim is to use a script written in IDL, into python:
IDL code:
PRO PS_GS
; Start the application
e = ENVI()
;Generate the roi from a vector file
; Open a vector file
file_vec = Filepath('Sic_Trapani.shp', ROOT_DIR = 'E:\mydirectory\')
vettore = e.OpenVector(file_vec)
; Get the task from the catalog of ENVITasks
Task_VtoR = ENVITask('VectorRecordsToROI')
; Define inputs
Task_VtoR.INPUT_VECTOR = vettore
; Define outputs
Task_VtoR.OUTPUT_ROI_URI = Filepath('roi_roi.xml', ROOT_DIR = 'E:\mydirectory\')
;Run the task
Task_VtoR.Execute
END
The above code, launched into IDL command prompt, works correctly.
I want make a python script that:
- option 1) launch the above idl .pro script
- option 2) use the IDL to Python Bridge sintax.
In the first case, using the `subprocess.call("idldirectory\idl.exe")` command, i can open the IDL prompt into the windows command prompt. But i can not execute any IDL function like a simple `PRINT, 'hello'`.
In the second case, i write the following poython code:
import subprocess
from subprocess import call
import idlpy
from idlpy import IDL
e=IDL.ENVI()
msi_file = """IDL.Filepath(mydata.tif", ROOT_DIR = 'mydirectory')"""
msi_raster = IDL.OpenRaster(msi_file)
The instruction `e=IDL.ENVI()` work correctly, in fact an Envi setion starts.
The instruction `msi_file = """IDL.Filepath(mydata.tif", ROOT_DIR = 'mydirectory')"""` work correctly.
My problem is with the OpenRaster instruction. It is an ENVI instruction and not an IDL instruction. So, IDL.OpenRaster does not work, and i do not have any solutions.
I have modified the code like:
msi_raster=IDL.ENVI().OpenRaster(msi_file)
The result is the following error message:
Impossible find the access point
??0LTISceneBuffer@LizardTech@@QEAA@AEBVLTIPixel@1@IIPEAPEAX@ Z
into the dynamic link library lti_DSDK.dll
Googling i have found this site:
Malware scan of gdal110.dll
Any help or suggestion? Thanks

Hi,
regarding Option 1:
Try compiling your file:
resolve_routine, 'PS_GS', /compile_full_file, /either
resolve_all
save, /routines, 'yourDirectory\ps_gs.sav'
Then try calling
subprocess.call("idldirectory\idlrt.exe yourDirectory\ps_gs.sav")
This works on my pc. I don't have Envi to test it though... I made a simple file with just
p = plot(/test)
inside and it works.
I didn't test the call from python, but it works from the command line.
Cheers,
Helder

You have a reference to the ENVI object in your variable "e". Use this syntax instead:
msi_raster = e.OpenRaster(msi_file)

For Jim P.
The sintax msi_raster=e.OpenRaster(msi_file) generate the same lti_dsdk.dll error.

This must be a platform specific bug. The LizardTech library is a 3rd party tool used to handle certain types of image compression.
Is the msi_raster object reference valid, in spite of the error message?
If you haven't done so already, please report this issue to support@exelisvis.com, along with the information about your platform and the format of the file you are attempting to read.
