Project Properties

In Visual Studio, the non-default property configuration for the projects are:

• Configuration Properties > General > Output Directory = [executables output file path] e.g. "....\Executables"
• Configuration Properties > Advanced > Character Set = Use Multi-Bye Character Set
• Configuration Properties > Debugging > Command Arguments = [input bmp file path] [output bmp file path] [threhold T] e.g. "..\Data\lenna_mono.bmp ..\Data\out.bmp 100"
• C/C++ > Preprocessor > Preprocessor Definitions = WIN32; _CRT_SECURE_NO_DEPRECATE

Steps to Run

1. Open Visual Studio
2. Open the Project3/Project3.sln
3. Configure the Project Properties as above
4. Run the desired tasks using the command line arguments below:

To run Task 1 give the following command line arguments: [input bmp file path] [output bmp file path] [threshold T]

To run Task 2 give the following command line arguments: [input bmp file path] [output bmp file path] [structuring set location pairs]

To run Task 3 give the following command line arguments: [input bmp file path] [output bmp file path] [radius r]

To run Task 4 give the following command line arguments: [input bmp file path] [output bmp file path] [zero pad = 1 or 0]

To run Task 5 give the following command line arguments: [input bmp file path] [output bmp file path] [structuring set location pairs OR radius r]

To run Task 6 give the following command line arguments: [input bmp file path] [output bmp file path] [structuring set location pairs OR radius r]
