BitMapFilter

This program applies various filters to BMP images. It supports the following filters:

• Blur (b)
• Grayscale (g)
• Reflection (r)
• Sepia (s)

Usage

To use the program, run the following command:

./filter [flag] infile outfile

Replace [flag] with the filter flag (e.g., b for blur, g for grayscale, etc.), infile with the input BMP file, and outfile with the output BMP file.

Example

To blur an image named input.bmp and save the result as output.bmp, use the following command:

./filter b input.bmp output.bmp

Requirements

• Standard C library (stdio.h, stdlib.h)
• getopt.h for command-line argument parsing
• helpers.h for image processing functions
• math.h for round function

Building the Program

To build the program, compile using the Makefile:

make filter

Notes

• The input image must be a 24-bit uncompressed BMP 4.0 file.
• Only one filter can be applied at a time.
