Temporary purpose of method is to take in a fixed byte array (Which is
a 8bit grey scale image) only take a region of the byte array, then
return that region. I have successfully used setByteArrayRegion to
take the incoming array(From Java code) and assign it to the outgoing
"imageData" with the correct size(back to Java code). BUT: I desire
to use getByteArrayRegion so i can choose a starting point on the
Incoming array, nto a starting point on the outgoing array. There is
a few bytes of an artifact in the beginning of the image i would like
to avoid.
Errors: When used in this way currently, imageData_out becomes much
larger than originally assigned, 10 to 20 times larger. ALSO, I do
get a Seg fault at the same time (See bottom). this is likely what is
causing the issue. Its been frustrating me for days because it makes
no sense for it to do this when the other method works perfect.
If anyone has any idea or place i could look....Thanks in advance. I
have dug through many sites and forums and i cant understand how i
could be using it wrong. Eventually the byte data will be operated on
in the c code.
