Dear Mathgroup,

I am a new member of Mathematica. I am trying to make communication between
Mathematica and one external image processing broad.   I have a
communcation program which can transfer data between the broad and windows
environment and   I 've made a  test program to link  the C  program with
Mathematica through MathLink. The main problem I encounter now is about
data type conversion when I try to send an image from external program to
Mathlematica..
The data type I received from  broad is BYTE and I only found three data
type which MathLink accepts. They are Integer, Real and String(char*).  I
tried to use MLPutString, since it accept a char*,but I got something else.
Then I tried to convert a BYTE* to int* before I send to MathLink and it's
OK. However   It consumes memory and time.  Can I have a better solution?




Thanks for any help.
