imwrite function in c++ shared library
显示 更早的评论
Greetings,
I am compiling a matlab code which has the imwrite function in it. I want it to create an image file and write it to the disk when the c++ code calls my dll. The problem is it does not output the image file. Is it not possible to use imwrite function in a c++ shared library? If it is so, are there any alternatives to this function that will create an image file in a predefined path the user provides?

Do you use MATLAB Coder or Compiler SDK for creating a dll?

imwrite is supported in Compiler SDK. What is your code for calling your dll?

Yes, and MATLAB function, if possible. Don't you get any error?

Note here the difference between MATLAB Compiler SDK and MATLAB Coder.
MATLAB Coder would be for stand-alone code generation; imwrite() is not supported for that purpose.
MATLAB Compiler SDK would be for generating a DLL that called into the MATLAB Engine to do the work, requiring that MCR be present. imwrite is supported for that purpose.
I interpreted your "compile" as meaning code generation, but Kojiro Saito is correct that you could easily have meant Compiler SDK.

imwrite() is not supported for code generation, for any file type.
(and imread() supports code generation only for reading 8 bit JPEG.)
You can find external libraries to write files, such as libjpeg and libtiff and libpng
