[vtkusers] The simplest question i guess......vtkShortArray()

[ALIZIER Julien AUSY]

Hi Rohan Naukudkar,


Have you tried :

"void vtkShortArray::SetArray  (short * array, vtkIdType size,  int save)   
 
   This method lets the user specify data to be held by the array. The array
argument is a pointer to the data. size is the size of the array supplied by
the user. Set save to 1 to keep the class from deleting the array when it
cleans up or reallocates memory. The class uses the actual array provided;
it does not copy the data from the suppled array. "

HTH

Hi Everyone,
    I have a image file of 15MB of type short. I want to read this file into
a vtkShortArray. I am using JAVA and VTK. I am doing it this way,
    vtkShortArray arr = new vtkShortArray();
 and then using the arr.InsertNextValue() method for inserting the elements
of the array which is taking a lot more time for me. Since i am using java
each time i insert an element into an array then its making a native call
and is going out of the Java Virtual Machine and so its taking very much
time (almost 6-7 min).
    Does any body have an idea how to pass the java array to a vtkShortArray
as reference so that the bulk of the data can be passed as a chunk data...

Thanks in advance,
cheers ,
Rohan
