fbgrab

fbgrab is a simple command-line utility for capturing the current frame in the framebuffer and saving it as a .bmp file. It includes an option for optional lossy compression suitable for thumbnailing.

Usage

./fbgrab --input/-i <input_file> --output/-o <output_file> --resolution/-r <resolution>

Options

• --input/-i: Specifies the input file (framebuffer device). This is an optional parameter.
• --output/-o: Specifies the output file where the captured frame will be saved as a .bmp file. This is an optional parameter.
• --resolution/-r: Specifies the fraction of the original captured frame. This is an optional parameter.

Example

./fbgrab -i /dev/fb0 -o output.bmp -r 4

This example captures the current frame from the framebuffer device /dev/fb0, saves it as output.bmp, and saves it as 1/4th of the original frame resolution.
