ImageProcessor

ImageProcessor is a CLI program for applying various filters to images (currently only BMP is available).

Program usage

You should run the program with the following arguments:

./image_processor {input_path.bmp} {output_path.bmp} [-{filter name 1} [params ...]] [-{filter name 2} [params ...]] ...

When run without arguments or with --help argument, the program displays help.

Example:

./image_processor input.bmp /tmp/output.bmp -crop 800 600 -gs -blur 0.5

In this example

1. Image is loaded from file input.bmp
2. Image is cropped to the size of 800x600 starting from the point of upper left corner
3. Converted to shades of gray
4. Gaussian blur with sigma = 0.5 applied
5. The resulting image is saved to the file /tmp/output.bmp

Filters are applied in the order they are listed in the command line arguments.

Available filters

1. -crop [int:width] [int:height] crops the image leaving widthxheight image counting from upper left corner
2. -gs makes the image grayscale
3. -sharp slightly increases image sharpness
4. -edge [float:threshold] (0 < threshold < 1) highlights image edges
5. -blur [float:sigma] applies Gaussian blur to the image
6. -median [int:size] applies Median blur to the image (sets each pixel to the median of nearest sizexsize pixels)
